Hydraulic roller crusher is used for crushing materials with middle and high hardness, such as metallurgy, building materials, refractory materials and other industrial lines The series hydraulic roller crusher is mainly composed of the parts of roller, the roller support bearings, pressing and adjusting device, and driving device etc..The adjustment of output size: there is adjusting device of wedge shaped or gasket between the two rollers, it has the adjusting bolt on the top of the wedge shaped device, when the adjusting bolt make the wedge be pulled up, the mobile roller wheel be forced to be away from the fixed wheel by wedge.

1. It used for crushing of special solid materials, which can be designed according to the material hardness, namely, testing the pressure resistance as per the materials provided by customers, and then designing roller crushers parameters. 2. Mobile Roller, fixed roller and power adopt the hard connection, i.e. coupling device, mobile roller is used the technology of universal joint, which completely avoids the greatest flaw about belt slippage of the outdated type belt (block material). 3. Roller surface is completely adopted cone welding technology of the large hydraulic roller crusher; it can produce more than 80,000 tons after repairing welding once, with the cost about 1000 RMB. The maintenance of whole machine in one year does not exceed 2000 RMB. 4. Feeder adopts the structure of unpowered choosing powder, before the material into the roller crusher, first passing through the device of unpowered choose powder, and less than 3-8 mm of material will be separated and it cannot be into the roller crusher, but the coarse material only be into the vibrating feeder, and evenly and unfolded going into the roller crusher, which can greatly improve the crushing efficiency. 5. Power consumption is one half of hammer crusher 6. When the material is too hard to be crushed, the roller will be back down automatically under the action of the spring, it make the rollers gap increase, the hard material or the material cannot be crushed will be fell down, so as to protect the machine from being damaged. Adjust the rollers gap can control the output size or granularity and then change the capacity per hour.

Hydraulic roller crusher is used of the surface friction making the rollers bite the materials into the broken zone, to make the material be squeezing or splitting. When it is used in coarse crushing or when it needs to increase crushing ratio, which often make teeth or grooves on the surface of the roller to improve fracturing effect.

Jaw crushers are immensely powerful machines, able to process and reduce aggregate and demolition material efficiently. Despite their powerful nature, they are not immune from damage and generally require a safety device called a toggle plate to protect them.

A toggle plate basically operates like a fuse. If any material enters a jaw crusher that cannot be crushed, whether due to its size or composition, the toggle plate is meant to break, relaxing the moving jaw open to allow for the uncrushable material to fall through or be removed manually.

Traditionally, jaw crusher toggle plates are made of metal machined or cast in a way that they are expected to fracture or bend at a certain pressure, indicating something too hard is in the crushing chamber.

However, for many jaw crusher owners and operators, spending time to remove broken toggle plates, spending money to replace them, and spending even more time to reinstall them incurs a substantial cost.

Instead of the toggle self-destructing when an uncrushable material enters the jaw crusher, a hydraulic relief system simply relies on its hydraulic technology to relax automatically, allowing the material to pass through or be removed, and then to reset.

The hydraulic toggle relief system was engineered to serve as a sustainable alternative to its consumable equivalent, eliminating the need to replace fractured toggles. However, traditional hydraulic toggle or relief systems require extremely high pressures in the system to achieve the necessary forces required to hold the jaw in place for crushing.

The Eagle Crusher hydraulic toggle relief system is available to be equipped onto any Eagle Crusher jaw crushers and will reduce unexpected downtime, decrease unnecessary replacement costs, and keep you up and running.

The unique, patent-pending system differentiates itself from other hydraulic systems as it utilizes much lower hydraulic pressures to hold the toggle in place, increasing durability and reducing risk of system failure.

automatic can crushers

Crushing cans can be a long and hard process when you have a bag with empty aluminum soda or beer cans after a party, and although a regular can crusheror a semi-automatic can crusher can make this process a lot more efficient, you can still get tired easily after few dozens of aluminum cans compressed. So to make this process even more effective some handy people have made their own automatic can crushers. These tools are made using various technologies such as electricity, pneumatic or hydraulic cylinders to power crushers from a metal, wood or even a plastic construction. There are also some commercial automatic can crushers, but these devices usually cost a lot more than regular crushers or homemade tools and are used in industrial applications. I tried to find the most practical, creative and interesting automatic can crushers on the internet and have categorised them by the technology they use to compress aluminum cans, either with air or pneumatic cylinders, electric engines or hydraulic cylinders.

Pneumatic can crushers are one of the most popular automatic can crushers because they are easier and cheaper to build than, for example, hydraulic can crushers. Pneumatic can crusher means that the tool has got a pneumatic cylinder which works with air compression, compressed air moves a special crushing plate which stomps a can inserted into a crushing opening. There are many different designs for pneumatic can crushers and you can find DIY plans for making these crushers. Here I have gathered some interesting homemade concepts of pneumatic can crushers.

I choose this pneumatic can crusher as it uses a different material like most other automatic can crushers, the construction of the crusher is made from a PVC plastic, almost any other unit I have found is made either from a metal or wood. Using plastic makes this a very cheap to make tool. On this websiteyou can purchase blueprint for the tool, so you can build it by yourself. The crusher works with a pneumatic cylinder that stomps cans in approx. 1 inch size from the looks. Fast and easy to use tool. One thing I would like to see on this tool is an automatic can feeding system as seen on other homemade pneumatic crushers, which would make the crushing process even more efficient.

The next type of automatic can crusher I found interesting was this kevinkrusher, they make various types of pneumatic can crushers that will crush 12 oz and 16 oz large cans. Two main things I liked about this product, first it has got a very durable metal design and looks like it would last a long time, and second you can actually purchase this automatic can crusher from their websitefor about 130-160 dollars per unit. This is a lot more than for a manual can crusher, but from the other hand, it makes can crushing a lot more easier and faster. I dont know about the shipping prices of the product, but there is a contact page on their website so you can ask them any questions about the product.

EZ Power Crusher has a well-considered design and works with the same pneumatic piston. The crusher has got an all steel body. The clever part of this automatic can crusher is that doors work as an activator for the crushing mechanism, you must open the door, insert an aluminum can into an opening and closing the door will activate the crushing mechanism, the can will get compressed and escalated on the bottom of the crusher. I liked this design because it makes can crushing with automatic crusher safer as most homemade crushers are pretty dangerous devices that must be operated with extra caution, especially if there are children around. Unfortunately, as for now the website where you could purchase the tool is not working and we dont have any information when or if the crusher will be sold again in the future.

The last pneumatic can crusher we found interesting was this wooden can crusher on some forum. This tool has got a wooden frame, where inside a pneumatic cylinder is placed. A can needs to be inserted in the opening with two metal plates on both sides and gets compressed with a pneumatic piston. One thing that this mechanism should have is an opening at the bottom of the crusher where the compressed can could fall out after it has been crushed.

From the design of the tool this is one of my all time favourite aluminum can crusher ever. The person who made this tool certainly has got an experience and knowledge in working with wood. The crusher has got a pneumatic cylinder to compress cans, has a glass on top of the cylinder, so you can see the cylinder working and there also is a hole on the bottom of the crusher, where empty cans drop out, so you can place a trash can directly below the tool.

This is not the best looking automatic can crusher, but is one of the fastest we have seen. It uses a very similar can holder baskets as semi-automatic can crushersto store multiple cans which allow to speed up the crushing process.

This is hands down the best pneumatic can crusher I have seen, it works fully automatic and the author of this tool even has made an interesting video showing the workings of this amazing crusher. Just enjoy!

While most pneumatic can crushers have quite similar design, the electric can crushers look quite different one from each other. There are various unique designs for electric can crushers and we have listed the most interesting ones below. These electric can crushers work automatically using some sort of electric engine and gear system on most crushers. The thing that differs these automatic can crushers from for example pneumatic crushers, is that they work fully automatically and you dont have to press any buttons to crush cans, just turn the machine on, drop some cans in and turn it off afterwards. However, this automatic working also makes most of these homemade tools more dangerous to operate.

This is one of the first electric can crushers I found and it immediately stood out from most other automatic can crushers thanks to the can feeding system. The crusher is made from an old engine, has got both metal and wood parts. What makes it unique is that approx. 7 cans can be inserted into the can feeder, which allows to speed the crushing process quite a lot, because you dont need to place cans in one by one, but can insert 7 cans at a time. We also found that the same person has constructed a pneumatic can crusher so make sure to check out his channels for inspiration to build your own automatic can crusher.

This is also an interesting approach to building an automatic can crusher that we have seen being done by several other people. This person has build the crusher using an old garage opener as engine for crushing cans, with parts from an old bicycle to move the crushing plate and the frame of the tool is made from wood. It also automatically dispenses crushed cans at the bottom. This is not the best looking tool and it takes quite a lot of space, but it works very well and crushes aluminum cans at a decent rate to less than an inch size.

This a very interesting and creative concept for an electric can crusher form a popular YouTube channel The Ben Heck Show, where Ben shows step by step how he plans, designs and makes an electric can crusher out of PVC plastic and aluminum. The video has got two episodes so make sure to check both of them out as they are very entertaining and show a very unique way to build an automatic can crusher with an electric motor.

This again is a very unique electric can crusher that uses an electric engine to compress aluminum cans, but what makes this so interesting is that the engine gets started only when a can gets dropped inside the crushing opening, because there is a laser sensor inside the opening that scans when an object is inserted into the opening, compressed cans drop in the box under the crusher. The laser sensor is an interesting addition to the crusher and other electric crusher on this list could also implement this technology to improve their products.

This is one of the fastest electric aluminum can crushers I have seen. The construction of the tool seems very basic but is clever at the same time. The crusher is made from three main parts, the motor that moves wheel of an old bicycle, which moves cranks with two metal bars and large wooden blocks at the end as crushing plates. Cans are inserted into a special wood box, crusher allows to crush two cans almost similarly, which speeds up the crushing process quite a lot.

Automatic can crushers with hydraulic cylinders are definitely the most hardcore crushing tools that are not only way too powerful for crushing aluminum drink cans, but some of them are also very fast. There arent practically any hydraulic can crushers you can purchase for home use, there are some industrial can crushers that cost couple of thousand dollars and are used for crushing large steel buckets and cans, but these are not exactly efficient for crushing small soda and beer cans. So if you want a hydraulic can crusher, you will probably need to build one by yourself. Here I have made a list of few different hydraulic can crushers I found.

This is one of the most heavy duty automatic can crusher I have seen. The unit can crush 250 aluminum cans in just over 2 minutes, which is impressive. The crusher is made from metal and has got a basket on the top that can store up to 500 empty cans, compering other automatic can crushers with can baskets that will hold maybe 10 cans, this unit is a beast. The hydraulic ram gets powered by a hydraulic power unit. Of course the crusher takes up a lot of space, is very loud and is not the most attractive tool, but from the effectiveness this tool is hard to beat.

I chose this can crusher because it is a very interesting experiment that can teach kids the basics of physics and hydraulics. This of course is not a very practical can crusher and cannot compete with other crushers and is actually not automatic, but anyway I liked the idea behind this experiment and so included the crusher in this list. The experiment simulates how a larger 4 post hydraulic stands used in automotive and many other industries work. This experiment can also be purchased in Pitsco website.

This is another interesting approach to can crushing, a hydraulic wood splitter is used as automatic can crusher that can compress cans one by one. This is not the most practical can crusher I have seen, but the approach is definitely very creative that is why I included this concept in this article. What I liked about this crusher is that it can compress not only aluminum soda and beer cans but more durable steel food cans and crushes them to a very small size in just few seconds.

One of the most creative automatic can crushing systems I have seen is this one, which works with a garden hose pressure. The crusher is built into backyard and is constructed from a metal frame with hydraulic cylinder that crushes cans. The cylinder is powered with a regular garden hose pressure and uses an electric computer and electric sprinkler valves. Cans need to be inserted into the crusher one by one and drops below the crusher after compression.

This experiment is definitely the next level can crusher. The tool is powered by an diesel engine and crushes cans with a huge amount of force making a very thin sheet of aluminum out of them. This tool compresses cans to the thinnest size of all crushers I have seen. Of course this is a huge overkill for a device that just needs to compress aluminum beer and soda cans, but this can crusher must be very fun to build and use.

In this article I wanted to show various types of automatic can crushers there are. Most of these tools are homemade and are not for sale, while some can be bought, but the price is still many times larger than for regular, manual can crushers. These automatic crushers make the crushing of aluminum cans more effective, faster and effortless, but unless you need to crush hundreds of cans each week, you could easily use a non-automatic can crusher. Of course, I would be happy if there were some mass produced automatic can crushers, for example, with a pneumatic cylinder, which would not take a lot of space and would cost about 100 dollars, but I havent seen such devices yet, so the only chance you can have an automatic crusher is to purchase one of few devices available for 200 and more dollars or to build one yourself, which is going to cost you a lot less and is going to be entertaining to build. However, if automatic can crusher is not what you are interested in or just need to compress few dozens of cans a month, check out our top lists of manual can crushers.

cone crushers for sale

The cone crusherwas designed primarily with a view to achieving top performance in the field of fine-reduction crushing. It has also been adapted to what is designated simply as fine crushing, which extends into a range below that ordinarily defined by the term fine-reduction. Although the eccentric speeds of the various sizes of this type are not quite so high as the speeds used for the Newhouse crusher, the Hydro-cone crusher definitely rates as a high-speed machine, its product comparing quite closely to that of the former type, for equal close-side settings.Probably the outstanding feature of the. Hydrocone crusher is the hydraulic support, from which its name is derived and which is clearly shown in the sectional view. This device makes it possible to adjust the crusher to any desired setting within its range in a matter of seconds;adjustments may be made while the crusher is running, although the feed must be shut off before operating the adjusting pump. An accumulator in the hydraulic system provides protection against tramp iron or packing.

Cone crushers are used in AG and SAG grinding circuits to increase tonnage by effectively dealing with any pebble (critical size) build-up problem. Normally, heavy-duty short-head crushers are employed to crush pebbles. Power and crusher cavity level are the key variables for monitoring and controlling the crusher operation. Crusher product size is adjusted by changing the closed side setting.

On the left is a diagram of the Hydro-cone crushing chamber. A comparison of this chamber with those previously discussed is interesting. It will be noted that the choke-point has been raised far above the discharge level, in fact, to a point not far below the nip-point for the recommended maximum one-way feed dimension. By virtue of the decided flare of the head, and the corresponding flare of the top shell bore, the line-of-mean-diameters slopes sharply away from the crusher centerline. For some, distance above the discharge point the angle between head and concave is very acute; in fact, at the open-side position of the head, this zone is almost parallel. For recommended operating conditions, i.e., for safe combinations of throw and setting, and with screened feed, this type of crushing chamber does not approach anything like a choke or near-choke condition. For the combination shown in the diagram the ratio of volume reduction is almost 1:1 from zone 0-1 to zone 2-3 at the choke-point; consequently, if the crusher is given a screened feed (as all fine-reduction crushers should be) the reduction in voids by the time the choke-point is reached cannot very well reach serious proportions. The diagram shows the standard chamber. With screened feed, these crushers will operate at closed-side discharge settings equal to the throw of the head at the discharge point (usually spoken of as eccentric-throw.)

The level in the crusher feed pocket is an important variable since it can indicate whether the feed is building up. A build-up could lead to a plugin the feed chute, a spill through the skirting on the crusher feed, or a crusher plug. None of these are desirable.

In a normal feed situation, the level in the crusher cavity is kept fairly low, just enough to ensure that there is sufficient feed to keep the crusher working, but if the feed has to be suspended suddenly because of impending plugging, the crush-out wont take too long (10 seconds or less). Normal feed is usually used in standard crushers where the feed particle size is quite large, say greater than 65 mm.

Choke feed is when the crusher cavity is kept full, without spilling out through the skirting. Choke feeding is usually used in short-head crushers where the feed particle is smaller than that for a standard crusher.

This crusher is a modification of the standard machine, developed for fine-crushing duty. Mechanically, the machine is the same in every respect as the standard crusher of the same type, but for each developed size of machine a special top shell and the concave ring has been designed, with reduced receiving opening, reduced angularity between head and concave, and, consequently, superior characteristics at the finer settings. Medium crushing chambers may be operated at close-side settings of one-half the eccentric-throw, on screened feed; hence capacities at the finer settings are better than those of the standard type. Fine crushing chambers operate at one-fourth the eccentric throw. Inasmuch as the maximum feed size is smaller in the case of the fine chamber, the ratios of reduction are approximately the same for both machines.

There are two main types of cone crushers: standard and shorthead. They differ by the shape of the cavity. The standard crusher cavity is wider to accommodate larger feed-size material. The short head crusher is designed to crush finer material and to produce a finer product.

The closest approach between the mantle and the bowl liner is called the closed side setting. This is usually specified by the metallurgist to give the desired crusher product discharge size. It can be checked by running the crusher empty, hanging a lead plug into the crusher bowl, and then removing it to measure the gap. The gap is adjusted by rotating the bowl. Some crushers are equipped with a hydraulic jack mechanism on the crushing head assembly instead of having a bowl adjustment ring. The head can be raised or lowered to meet the operators needs. It can be very helpful in operation and process control.

The Symons Cone Crusher has come into almost universal use during the last few years for the final stage of crushing. It is a development of the secondary gyratory crusher, which is merely a small gyratory crusher designed to break the product of the primary machine down to about 1-in. size; but the main shaft of a cone crusher instead of being suspended from a spider is supported on a large socket bearing situated immediately under the crushing head and protected from grit and dust by a sealing assembly, this bearing taking the whole of the crushing load.

Fig. 8 gives a sectional view of the machine. The main shaft is carried in a long gear-driven eccentric, the rotation of which causes the gyration of the head in the usual way, but the center of gyration is at the apex of the crushing head instead of in the spider. At the top of the bowl, therefore, the lumps of ore entering the crushing zone are cracked by short powerful strokes; but at the bottom the head has a much longer but less powerful stroke, enabling the ore in the finishing stages to be rapidly crushed and quickly discharged without any tendency to choke, a condition which reduces over crushing to a minimum. This, together with the curved shape of the bowl, accounts for the large reduction ratio possible with this type of machine and makes it superior to other secondary crushers and coarse rolls.

It will be seen that the head and the bowl are parallel at the lower part of the crushing zone. The parallel space is deep enough, in conjunction with the speed of gyration, to ensure that no piece of ore can pass through it without being struck two or three times by the head before it falls clear. It follows that, unlike the jaw and gyratory crushers, the size of the product is determined by the distance apart of the bottom edges of the head and bowl in the position when they are closest together.

Coarse buttress threads on the outer circumference of the bowl fit into corresponding threads on the inner side of the adjusting ring, which is held down to the mainframe by a circle of long heavy springs, flexible enough to allow the whole assembly to rise should tramp iron or other uncrushable material enters the crushing zone. By means of a windlass and chain, the bowl can be rotated in the threads that support it in the adjusting ring while the machine is running, thus enabling the bowl liner to be adjusted for wear or the size of the product to be changed without stopping. The cone crusher is usually set to give a 3/8-in. or -in. product when discharging to ball mills.

Table 9 gives particulars of the different sizes of crushers. The capacity figures are based on material weighing 100 lb. per cubic foot and must be increased in direct proportions for heavier ores. It will be noted that each size of machine has two ranges of capacity; this is due to the fact that it can be fitted with a coarse or a fine crushing bowl according to the duty that is required of it. With either one, the range of reduction is greater than is economically possible with any other type of dry crushing machine.

A possible disadvantage of the cone crusher is that as a rule it cannot be choke-fed, but must be given an even feed of ore if it is to do efficient work. Should circumstances call for the installation of a machine that can be run if necessary with the ore piled up over the top of the head, a secondary gyratory crusher of the suspended shaft type will be required. The Traylor Reduction Crusher Type TZ, which is constructed on the principles of an ordinary gyratory crusher, but is fitted with a curved bowl liner similar to that of the Symons Cone Crusher, is designed to meet the case. Although the suspension of the shaft restricts the movement of the head to a smaller circle of gyration than that of the cone crusher, the ratio of reduction is still large enough to enable it to crush the product of the primary breaker to -in. size (-in. for the large machines), and it fulfills the condition that it can be choke-fed. Owing to the smaller movement of the head, however, the capacity for a given range is much less than that of the equivalent size of cone crusher, and the latter is therefore preferred when choke-feeding can be avoided.

The Symons Shorthead Cone Crusher, which is constructed on the same general principles as the larger machine, is designed to follow the latter, taking its product at 1-in. and reducing it to about -in. size. The strains imposed on the crushing members, however, would be very heavy if the machine were run with the discharge opening set to -in. or less. It is usual, therefore, to crush in closed circuit with a screen, the discharge opening of the bowl being set to 5/8 or in. Thus a circulating load is built up and a certain amount of choke-crushing takes place, but the method actually gives greater efficiency with a finer product than can be obtained in an open circuit, whatever the discharge setting of the bowl in the latter case.

In ordinary crushing practice, the grinding section is supplied with -in. or 3/8-in. material direct from Symons Cone Crushers. But the demand is for a finer feed and it seems likely that the Shorthead Cone Crusher will satisfy this demand to the exclusion of fine crushing rolls.

Symons Cone Crushers have been used extensively for secondary crushing in metallic, non-metallic, rock products, and industrial operations. The Symons Cone was developed to give large capacity, fine crushing. The combination of high speed and wide travel of the cone results in a series of rapid, hammer-like blows on the material as it passes through the crushing cavity and permits the free flow of material through the cavity.

Reduction in size of any particle, with each impact of the head, is regulated by the opening between the head and bowl at that point. A threaded arrangement of the bowl affords a quick and easy method for changing the size of the product or to compensate for wear. This adjustment can be made while the crusher is operating. A parallel zone between the lower portion of the crushing members assures uniform sizing.

Frame, adjustment ring, and cone are made of cast steel; gears are made of specially treated steel and have cut teeth; all bearings are bronze; mantle and bowl liners are manganese steel. The head and shaft can be removed as a unit, and other parts such as the eccentric and thrust bearings can easily be lifted out after the head is removed. The countershaft assembly can also be removed as a complete unit.

The circle of heavy coil springs, which holds the bowl and adjustment ring down firmly onto the frame, provides automatic protection against damage due to tramp iron. These springs compress, allowing the bowl to rise the full movement of the head until non-crushable material passes through. The springs then automatically return to their normal position.

Symons Cone Crushers are made in Standard and Short Head types. They are of the same general construction but differ in the shape of the crushing cavity. The Standard cone is used for intermediate crushing. The Short Head cone is used for finer crushing. It has a steeper angle of the head, a shorter crushing cavity, and greater movement of the head at the top of the crushing cavity.

If you observe the illustrations you will notice that the center line of the main shaft is at an angle to the center line of the crusher. The center of the main shaft bisects the center line of the crusher at the opening of the crushing chamber. As the MANTLE revolves that point is the pivot point of the mantle. This means that both the top and the bottom of the crusher mantle have a circular gyrating motion.

Tramp iron had long been a source of worry to those engaged in fine crushing.Here is what one operator had to say.Shutdowns were frequent, costs were uncertain because of enforced delays due to excessive breakage. Plugged machines had to be freed continually with a torch tocut out frozen and wedged-in tramp iron.The cone crusher overcame these troubles,helped reduce and stabilize costs. The bestevidence of this statement is the universalacceptance of the cone as the outstandingcrusher in its field.

While tramp iron is not recommended as a regular diet for a Cone Crusher, its construction is such that damage will not result should any ordinary noncrushable material get into the crushing cavity. The band of heavy coil springs encircling the frame allows the bowl to lift from its seat with each movement of the head until Such non-crushable object passes off into the discharge. The tramp iron shown in the accompanying illustration passed the protective devices installed for its removal and would have resulted in expensive repairs and long shutdown periods for any crusher except the Symons Cone.

Cone crushers can have two types of heads, standard and short head types. The principle difference between the two is in the shape (size and volume) of the crushing cavities and feed plate arrangements. Standard head cone crushers have cavities that are designed to take a primary crushed feed ranging up to 300mm generating product sizes around 20mm to 40mm. For finer products, short head cone crushers are normally used. They have a steeper angle of the head and a more parallel crushing cavity than the standard machines. Due to the more compact chamber volume and shorter working crushing length, the much needed higher crushing forces/power can be imparted to the smaller-sized material being fed to the crusher. Cavities for the short head machine are designed to produce a crushed product ranging from 5mm to 20mm in a closed circuit.

At the discharge end of the cone crusher is a parallel crushing section, where all material passing through must receive at least one impact. This ensures that all particles, which pass through the cone crusher, will have a maximum size, in at least one dimension, no larger than the set of the crusher. For this reason, the set of a cone crusher can be specified as the minimum discharge opening, being commonly known as the closed side setting (CSS).

Here are facts about the conecrusher known as Hydrocone. This line of hydraulically adjusted gyratory crushers was developed in smaller sizes some fifteen years ago by Allis-Chalmers to meet a demand for improved secondary or tertiary crushing units. The line is now expanded to include sizes up to 84-in. diameter cones.

This modern crusher is the result of many years of experience in building all types of crushing equipment, when the first gyratory or cone crusher, the Gates, was put into operation. Overall these years AC has followed a continuing policy of improvement in crusher engineering, changes in design being based on operating experience of crushers in actual operation.

The Hydrocone cone crusher is the logical outgrowth, a crusher having a means of rapidly changing product size or compensating for wear on the crushing surfaces a crusher which produces a better, more cubical product than any comparable crusher and a crusher so designed that it can be operated and maintained with a minimum of expense.

The most important fact about the Hydrocone crusher is its hydraulic principle of operation. Hydraulic control makes possible quick, accurate product size adjustments fast unloading of the crushing chamber in case of power failure or other emergency protection against tramp iron or other uncrushable materials in the crushing chamber. Another important fact about this crusher is its simplicity of design and operation. The accompanying sketch shows the simplicity of the Hydrocone crushers principle of operation. The main shaft assembly, including the crushing cone, is supported on a hydraulic jack. When oil is pumped into or out of the jack the mainshaft assembly is raised or lowered, changing the crusher setting.

Since the crushing cone is supported on a hydraulic jack, its position with respect to the concave ring, and therefore the crusher setting, can be controlled by the amount of oil in the hydraulic jack.

Speed-Set control raises or lowers the crushing shaft assembly hydraulically, and permits quick adjustment to produce precise product specifications without stopping the crusher. Speed-Set control also provides a convenient way to compensate for wear on crushing surfaces.

On Hydrocone crushers in sizes up to 48-in., the Speed-Set device is a hand-driven gear pump; on the larger sizes a motor-driven gear pump operated by push-button. On all sizes the setting can be changed in a matter of minutes by one man without additional equipment, reducing downtime materially.

Protection against tramp iron or other uncrushable materials is afforded by an accumulator in the hydraulic system. This consists of a neoprene rubber oil-resistant bladder inside a steel shell. This bladder is inflated with nitrogen to a predetermined pressure higher than the average pressures encountered during normal crushing.

Ordinarily, the Automatic Reset remains inoperative, but if steel or some other foreign material should enter the crushing chamber, the oil pressure in the hydraulic jack will exceed the gas pressure in the accumulator. The bladder will then compress, allowing the oil to enter the steel shell. This permits the crushing cone to lower and discharge the uncrushable material without damage to the crusher.

After the crushing chamber is freed of the foreign material, the gas pressure in the accumulator will again exceed the oil pressure in the hydraulic system. Oil is then expelled from the accumulator shell and the crushing cone is returned to its original operating setting automatically.

A Hydrocone crusher will produce a cubical product with excellent size distribution and a minimum of flats and slivers. This is especially important in the crushed stone industry where a cubical stone is required to meet rigid product specifications. It is also of considerable significance in the mining industry where the elimination of large amounts of tramp oversize reduces circulating loads or makes open circuit crushing possible.

The reason why the Hydrocone crusher will produce such a uniform, cubical product is that it has a small eccentric throw with respect to the crusher setting. This means a smaller effective ratio of reduction during each crushing stroke, and therefore, the production of fewer fines and slivers. Likewise, a small eccentric throw means a small open side setting, which results in a smaller top size of the product. A large percentage of the product from a Hydrocone crusher will be of a size equal to or finer than the close side setting.

For fine crushing, or in installations where the feed to the crusher is irregular, the use of a wobble plate feeder is recommended. This feeder is installed in place of the spider cap and affords a means of controlling the feed to the crusher, as well as a means of distributing the feed evenly around the crushing chamber.

Essentially, the feeder consists of a plate that is oscillated by a shaft extending down into the crushers main shaft. The motion of the main shaft oscillates or wobbles the feeder plate. The plate is supported on a rubber mounting which permits its motion and, at the same time, positively seals the top of the spider bearing against the entry of dust. Maintenance is reduced by the use of self-lubricating bushings between the feeder plate shaft and the crusher main shaft.

Hydrocone crushers are mounted on rubber machinery mountings in order to reduce installation costs and make it possible to locate these machines on the upper floors of crushing plants. These mountings operate without maintenance, absorb the gyrating motion of the crusher, thereby eliminating the need for massive foundations. Rubber mountings also prolong the life of the eccentric bearing, since this bearing is not subjected to the severe pounding encountered when rigid mountings are used.

The exclusion of dust and dirt from the internal mechanism of the crusher is of extreme importance from a maintenance standpoint. To accomplish this, Hydrocone crushers are equipped with one of the most effective dust seals yet devised.

This seal consists of a self-lubricating, graphite impregnated plastic ring which is supported from the head center in such a way that it is free to rotate, or gyrate, independently of the head center.

The plastic ring surrounds the dust collar with only a very slight clearance between the two parts. With the plastic ring being free to move as it is, it accommodates the rotation, gyration, and vertical movement of the main shaft assembly, maintaining the seal around the dust collar at all times. Because of its lightweight and self-lubricating characteristics, wear on the plastic ring is negligible.

The ease with which any wearing part can be replaced is of the utmost importance to any crusher operator. With this in mind, the Hydrocone crusher has been designed so that any part can be replaced by disturbing only a minimum number of other parts.

For example, the Mantalloy crushing surfaces are exposed by simply removing the top shell from the crusher. This can be done easily by removing the nuts from the studs at the top and bottom shell joint. The eccentric and hydraulic support mechanisms are serviced from underneath the crusher without disturbing any of the feeding arrangements, or the upper part of the crusher.

Efficient lubrication of all wearing parts is one of the reasons why crushing costs are low with the Hydrocone crusher. On most sizes, lubrication is divided into three distinct systems, each functioning independently.

This bearing, whether of the ball and socket type as on the smaller sizes, or of the hourglass design (as shown) found on the larger Hydrocone crushers, is pool lubricated. On the 51, 60 and 84-inch sizes, provision is made for introducing the lubricant from outside the top shell through the spider arm. On the smaller crushers, oil is introduced through an oil inlet in the spider cap. On all sizes, oil is retained in the bearing by a garter-type oil seal located in the base of the spider bearing.

All Hydrocone crushers are provided with a compact external lubrication system consisting of an oil storage tank, an independently motor-driven oil pump, a pressure-type oil filter, and a condenser-type cooler.

Cool, clean oil is pumped into the crusher from the conditioning tank, lubricating first the three-piece step bearing assembly. The oil then travels up the inner surface of the eccentric, lubricating the eccentric bearing and main shaft.

At the top of the eccentric, the oil is split into two paths. Part of the oil flow passes through ports in the eccentric and down its outer surface, lubricating the bronze bottom shell bushing, driving gears and wearing ring. On the 48-in. and smaller crushers, the balance of the oil overflows the eccentric and returns over the gears to the bottom of the crusher where it flows by gravity back into the conditioning tank. On the 51-in. and larger Hydrocone crushers, any oil which overflows the top of the eccentric is returned directly to the conditioning system without coming into contact with the gears.

On all but the 36 and 48-in. Hydrocone crushers, the countershaft bearings are of the anti-friction type with separate pool lubrication. Both ends of the countershaft bearing housing are sealed by garter spring-type oil seals to prevent dirt or other contaminants from entering the system.

Rather than use one eccentric throw under all operating conditions, Hydrocone crushers are designed to operate most efficiently with a predetermined ratio of eccentric throw to the crusher setting. By operating with an eccentric throw specifically selected for a given application, the most desirable crushing conditions are attained the most economical use of Mantalloy crushing surfaces reduced crusher maintenance a more cubical product.

The eccentric throw is controlled by a replaceable bronze sleeve in the cast steel eccentric. This sleeve, being a wearing part, can be renewed readily in the field. Also, should operating conditions change, the throw or motion of the crushing head can be changed accordingly.

Because of the large choice of eccentric throws available and the variety of crushing chambers that may be obtained a Hydrocone crusher may be selected that will fulfill the requirements of almost any secondary or tertiary crushing operation.

They may be used in the crushed stone industries to produce a premium cubical product in the mining industries to produce a grinding mill feed having a minimum of oversize, thereby reducing circulating loads and making open circuit crushing possible. The Hydrocone crusher is used in the cement industry to reduce cement clinker prior to finish grinding.

One of three general types of crushing chambers can be furnished for any size Hydrocone crusher to suit your specific needs. The selection of the proper chamber for a given application is dependent upon the feed size, the tonnage to be handled and the product desired. A crusher already in use can be readily converted to meet changing requirements, making this machine highly flexible in operation.

The Coarse crushing chamber affords the maximum feed opening for a given size crusher. Crushers fitted with a Coarse chamber can be choke fed, provided that product size material in the feed is removed.

The Coarse chamber has a relatively short parallel zone and is designed to be operated at a close side setting equal to or greater than the eccentric throw. For example, a crusher with a 3/8-in. the eccentric throw should be operated at a 3/8-in. (or more) close side setting, and therefore a -in. open side setting. Optimum capacity and product will result when operated under these conditions, as well as most economical wear on the mantalloy crushing surfaces.

One way dimension (slot size) of the feed to a crusher fitted with a Coarse chamber should not exceed two-thirds to 70 percent of the feed opening. The maximum feed size to an 848 Hydrocone crusher would therefore be about 5-in. one way dimension.

The use of a wobble plate feeder, furnished as optional equipment, is recommended if the feed size is relatively large, if the crusher is to be operated in closed circuit, or if the feed to the crusher is irregular.

If the Hydrocone crusher is operated with a Coarse crushing chamber, the product will average about 60% passing a square mesh testing sieve equal to the close side setting of the crusher. On certain materials which break very slabby, this percentage will be somewhat lower, and on cubically breaking material the percentage will be somewhat higher. As an average, approximately 90% of the product will pass a square mesh testing sieve corresponding to the open side setting, although this percentage frequently runs higher.

The Intermediate crushing chamber has a feed opening somewhat less than a coarse crushing chamber, but because of its longer parallel zone, is designed to be operated at a close side setting equal to or greater than half the eccentric throw. For example, with a -in. eccentric throw, the minimum close side setting would be 3/8-in.

Crushers fitted with this type of chamber can be choke fed, provided that product size material in the feed be removed ahead of the crusher. The one-way dimension or slot size of the feed to a crusher should not exceed approximately half the receiving opening. A 436 Hydrocone crusher with a 5/8-in. the eccentric throw could be operated at 5/16-in. close side setting and feed size should not exceed 2-in. one-way dimension.

The wobble plate feeder, although not required under most circumstances, is recommended if the feed is irregular, or if the crusher is operated as a re-crusher, at a relatively close setting, or in a closed circuit.

Because of the longer parallel zone in this crushing chamber, a somewhat greater percentage of the product will pass a square mesh testing sieve equal to the close side setting. This will usually average about 65 to 70%, with this percentage varying, depending on the material being crushed. Very frequently, 100% of the product will pass a square mesh testing sieve equal to the open side setting of the crusher.

The Fine crushing chamber has the longest parallel zone and therefore the smallest feed opening for any given size crusher. It can be operated at ratios of eccentric throw to close side setting of up to 4 to 1. With a -in. throw, for example, a 236 Hydro-cone crusher could be operated at 3/16-in. on the close side.

Because of their design, crushers with Fine crushing chambers cannot be choke fed but must be equipped with the wobble plate feeder. The maximum one-way dimension of the feed approaches the crusher feed opening. A 348 Hydrocone crusher can be fed with material up to 3-in. one-way dimension.

The Fine crushing chamber will give the highest percentage passing the close side setting of any of the chambers discussed here. The product will average approximately 75% passing a square mesh testing sieve equal to the close side setting. Because of the long parallel zone, the top size of the product will be only slightly larger than the close side setting of the crusher.

In addition to the three general types of crushing chambers described here, special chambers can be designed to meet varying operating requirements, giving the crusher even greater flexibility than can be obtained with these three main types.

For example, a special concave ring can be used in a 636 Hydro-cone crusher which will reduce the feed opening to 5 inches and permits a two to one ratio of eccentric throw to close side setting. Thus, the crusher can be furnished to fit the exact requirements of any application.

The following capacity table gives a complete range of all Hydrocone cone crusher capacities with varying crushing chambers and eccentric throws. This table shows the minimum recommended setting for any given eccentric throw, the recommended maximum one-way (slot size) dimension of the feed, and the maximum recommended horsepower for any eccentric throw.

Capacities given are based on crushing dry feed from which the product size material has been removed. The material must readily enter the feed opening and be evenly distributed around the crushing chamber. The table is based on material weighing 100 lb per cubic foot crushed. Any variation from this must be accounted for.

The curves on the following page can be used to approximate the screen analysis of the product from any given Hydrocone crusher. These curves are only approximations since the actual screen analysis of the product of a Hydrocone crusher will depend upon the nature of the material being crushed, the feed size and a number of other considerations which could not be taken into account in these curves. Within these limits, the curves should give fairly accurate estimates.

Note that the Coarse crushing chamber is represented as giving a product of which 60 percent will pass the close side setting, the Intermediate chamber 67 percent and the Fine chamber 75 percent passing the close side setting. These percentages are the averages of a large number of tests and some variations from these must be expected. If material breaks slabby the percentage with a coarse crushing chamber may be as low as 50 percent; if it breaks very cubically it might be as high as 70 percent, or even higher.

These curves have been prepared so that they can be used for any crushing chamber. To estimate the product of any Hydrocone crusher, it is necessary to know the type of crushing chamber used (Coarse, Intermediate or Fine), the close side setting and the eccentric throw.

If the crusher is a 636 Hydrocone crusher with a 3/8-in. throw and a 3/8-in. close side setting, the approximate screen analysis would be the curve that would pass through the 3/8-in. horizontal line and the vertical line representing the close side setting for the Coarse crushing chamber, which is the 60 percent passing line. If no curve passes through the precise point of intersection between the horizontal and vertical lines, an approximate curve can be sketched in which parallels the other curves. The same procedure can be used for approximating the products from any other crushing chamber.

We canprovide testing to solve the most difficult crushing problems. Laboratory equipment makes it possible to measure the crushing strengths and characteristics of rock or ore samples accurately, and this data is used in the selection of a crusher of proper size and type.

Impact and batch tests are frequently sufficient to indicate the type and size crusher that will be the most economical for a particular application. However, batch testing is often followed by pilot plant tests to provide additional information about large-scale operations, or to observe rock or ore reduction under actual plant operating conditions.

Pilot plant tests duplicate a continuous crushing operation provide a practical demonstration of the commercial potential of the process on a pilot scale. Such tests are useful because they may disclose factors that affect the full-scale operation, favorably or otherwise, but which remain hidden in tests on limited samples.

All Laboratory tests are guided by modern scientific knowledge of crushing fundamentals and by ourinvaluable backlog of experience in engineering and building all types of crushing equipment for any crushing application.

In addition to the facilities for crushing tests, the Laboratory maintains complete batch and pilot mill facilities for use in investigating an entire process. Tests in grinding, sizing, concentrating, thickening, filtering, drying, and pyro- processing can be made.
