The cast steel spider cap has been designed to serve as a feed distribution plate for coarse materials. It is recessed on the 22, 30, 36 and 48-in. crushers. For fine materials, the wobble plate feeder a more effective means of distributing the feed is recommended.

The annealed cast steel top shell and spider are made in one piece. The spider is of the three arm type, equipped with a self-aligning, Scor-Proof plastic ball and socket bearing in crusher sizes 22 to 48-in., and with an hourglass type bearing in sizes above 48-in. The lubricant is sealed in with a garter type oil seal. Bearings can be lubricated from outside the topshell on the 51, 60 and 84-in. crushers through oil holes in spider caps of the four smaller sizes.

The mainshaft is of high grade forged steel, annealed for stress relief. It is tapered to gauge for head center fit. The bottom of the shaft is fitted with a polished bronze step bearing. The journal for the spider bearing is formed by a sleeve shrunk on the shaft on the 51, 60 and 84-in. crushers. Short, heavy mainshaft design results in long life.

The step bearing consists of a bronze mainshaft step, a bronze piston wearing plate, and an alloy steel washer between the two. The washer is drilled for oil cooling and lubrication. Both the mainshaft step and the piston wearing plate are made of high lead bronze, selected to give the best bearing surface. The washer and plate are pinned in place, and the bearing surfaces are grooved to permit distribution of the lubricating oil.

The Mantalloy head mantle of this cone crusher is a replaceable wearing surface. It is made of alloyed manganese steel, and is held in place with a self-tightening head nut. On the 51-in. Hydrocone crushers and larger, the bottom portion of the mantle is ground to gauge to fit the head center, and the top portion is zinced. For crushers smaller than 51-in., the entire inner surface of the mantle is ground to gauge and no zincing is required.

The Mantalloy concave ring, or the stationary crushing surface, is available in three standard types, coarse, intermediate and fine. Helices, cast into the bottom of the concave ring, engage similar helices on the top of a cast steel concave support ring. The support ring is held by a key to the top shell to facilitate assembly, after which it is supported on the bottom shell. The helical surfaces make the concave ring self-tightening; no zincing is required.

The dust seal is a plastic ring suspended in a housing from the head center and encircling the dust collar. It is designed to accommodate the vertical adjustment and the gyrating and rotating motion of the head. All wearing parts are replaceable. The crusher is fitted with a connection for introducing low pressure air inside the seal for additional dust protection.

The eccentric is made of high carbon cast steel and fitted with a bronze inner wearing sleeve. The eccentric turns in a bronze bottom shell bushing. Both sleeve and bushing are replaceable. The eccentric throw can be changed in the field by installing a different sleeve.

The alloy steel pinion is mounted on a turned shaft. The cast steel pinionshaft housing is bolted to the machined opening in the bottom shell. It is equipped with anti-friction bearings sealed inside and out, and has separate pool lubrication in all sizes except the 36 and 48-inch machines. The 36 and 48-inch Hydrocone crushers have sleeve type counter-shaft bearings which are lubricated by the external oiling system.

The annealed cast steel bottom shell is of the three arm, open discharge type, bored to gauge for the top shell and eccentric bushing. It is bored and faced for the bottom plate, pinionshaft bearing and dust collar.

The external oil conditioning system furnished with Hydrocone crushers consists of a large oil storage tank on which are mounted a condenser type cooler, pressure type filter, motor, and a pump which pumps the lubricant to the crusher automatically. These units both cool and filter the oil. The accumulator and tank for the Automatic Reset are mounted separately from the oil storage tank.

All oil conditioning systems are equipped with oil flow and temperature safety switches which are adjusted to open the motor circuit and stop the crusher if the temperature becomes too high or if there is not a sufficient flow of oil. Flexible hose connects the lubricating unit to the crushers, greatly reducing the number of pipe fittings required and simplifying the installation.

Oil for the tank is pumped through the filter and cooler to the step bearing and up the inner eccentric bearing. It flows down the outer eccentric bearing, lubricates the gear and pinion, then returns to the tank. Tank capacities vary from 30 gallons for the 22-in. Hydrocone crusher to 240 gallons for the 84-in. machine.

CRUSHING CHAMBER may be any one of three standard types (Fine, Intermediate and Coarse) designed to assure a cubical, well-graded product. Shape of mantle and concave ring, and the range of adjustment available, results in maximum life and minimum scrap when replacing parts. Special crushing chambers also available.

BEVEL PINION AND GEAR are of the spiral design in the larger sizes provide greater tooth contact and smooth, trouble-free operation under most severe conditions. Bevel spur and pinion gears are used on smaller size Hydrocone crushers.

INNER CRUSHING CONE or mantle is one-piece Mantalloy casting held in place by a self-locking head nut. Complete contact of the ground inner surface with steel head center eliminates need for zincing in all but the larger sizes.

OUTER CRUSHING RING or concave ring is one-piece Mantalloy casting. Necessity of zincing or clamping concave ring in place is eliminated by ground-to-fit finish on outer surface and the use of an effective self-locking device.

3-PIECE STEP BEARING accommodates gyrating motion of main shaft and transmits crushing pressure to hydraulic piston. Designed to withstand bearing pressures much greater than those encountered in actual service.

While it is one of the major parts in the machine, there are few essential differences between the adjustment ring in the 10 ft. crusher and in the smaller machines, except as to size. Material of the ring which weighs 70,000 pounds is cast steel. Rigidity of the adjustment ring cross-section is essential. In this case, increased section thickness, with ordinary carbon steels, results in a reduction in deflection.

This part, which is screwed into the adjustment ring, is the means of setting of the machine. Adjustment is performed by rotating the bowl relative to the adjustment ring. In the 10 ft. machine provision has been made to adjust the setting during crushing. This increases the availability of the crusher substantially. Past practice had been to stop feed to the crusher during adjustment.

During crushing the position of the bowl and adjustment ring is maintained on the slant flank of the threads by means of the crushing force. The slant flank helps in centering the two elements. The clamp ring acts somewhat like a locking device to take up clearances. Ideally, the clamping cylinders do not have to have any greater capacity than is necessary to overcome the weight of the bowl. Practically, the clamp ring capacity is many times higher to withstand tramp passage.

To adjust the setting of the machine, hydraulic rams are used to rotate or counter-rotate the bowl in the adjustment ring. The seal between the adjustment cap and hopper is a simple, continuous, tightly fitting flap which allows free, relative rotation but prevents intrusion of dust into the thread area. The lower end of the thread connection between bowl and adjustment ring is also sealed. The hopper assembly, which is actually a part of the bowl assembly, including the hopper, hopper liner and cap closure, comprises the section in which the feed is introduced. It includes a dead bed, reducing wear and shock from the fall of the feed from the feeder above.

The adjustment rams are pressurized hydraulically and provide a setting adjustment. For normal adjustment of setting due to wear, installation and removal of the bowl is made through a swivel sheave and a cable turn applied around the adjustment cap. The bowl is then rotated by use of the maintenance crane.

The crushing head, similar in section to that of the 7 ft. machine, had three-dimensional photoelastic studies made using the technique of freezing stresses into a loaded plastic model, sectioning the model and examining the slices under polarized light. As a result of these techniques, stresses have been reduced. The core of the head consists of six massive ribs to support the crushing forces on the surface of the head. The head is cast steel.

The main shaft is of turbine rotor steel of high quality and refinement, the chemistry of which is low carbon to reduce the possibility of heat checking. It includes chrome nickel additions for deep hardening, notch toughness and resistance to fatigue. The shaft extension is provided to reduce the relative strain between the head and shaft and thereby reduce fretting in the fit, which has a heavy press. The shaft diameter is 50 percent greater than the 7 ft. crusher shaft. As a result, the shaft operates at lower values of bending stress and deflection. Reduced deflection produces distinct benefits in bearing behavior because of uniformity of oil film under load. Reduced stresses assure longer life and resistance to overloads.

The head-shaft assembly is supported by the socket and socket liner which is, in essence, a spherical thrust bearing. The function is to carry the vertical component of the crushing force while allowing the head to oscillate around the theoretical center of rotation.

The socket of carbon steel is of dowelled design. The forces between the head and the socket are normal to the spherical surface of the head and pass through the theoretical center. The line of action of these forces is such that practically pure compression is applied to the socket and liner, reducing deflection and stress to a minimum and promoting good bearing performance.

The force distribution throughout the crusher is based on a vector diagram of the cavity forces during crushing and the reactions at various associated loading points in the crusher. The vector diagram establishes their relative magnitude, direction and points of application. The actual magnitude of these forces is established by the crushing force necessary to lift the adjustment ring off the frame seat. This condition represents the maximum allowable force for normal crushing.

A baffle ring attached to the head is sub-merged around its entire periphery in a water trough resting on the socket. Dust tends to settle into the trough and must be continuously removed to prevent caking. For this reason, water is continuously fed through specially designed nozzles which scour the trough. Overflow water is carried off by internal piping and passages. The seal chamber is vented to atmosphere to prevent siphoning which may cause oil contamination of the water or vice versa.

The gears are straight tooth bevel gears and are designed to AGMA standards using a computerized program which, upon input of the basic information, such as DP, diameters, gear ratio, material properties, tooth type, provides a complete printout of the rated power on the basis of tooth strength and surface durability of the gear. The factor of safety on the gear is in excess of three on the strength basis and in excess of two on the durability basis.

single cylinder cone crusher with low price | fote machinery

A single-cylinder cone crusher can effectively crush the rock material into products with uniform particle size and beautiful grain shape. It is commonly used in the secondary and tertiary crushing stages for aggregate production, concrete recycling, and mining operations.

The secondary crushing equipment is designated as standard cone crushers and short-head cone crushers. The former ones have stepped liners, and the latter ones have smoother crushing faces and steeper cone angles of the breaking head.

The sing-cylinder crusher is suitable for various rocks no matter it is hard, soft, or abrasives. With proper operation, the running cost of the cone will be much lower than the impact crusher and will produce a less fine powder.

The cone crusher head has a maximum volumetric discharge. When a large amount of material is discharged, the maximum discharging volume makes the crusher process more material in each cycle and fill more material into the void left by the crushing head as it retreats.

Large head angle: It ensures trouble-free operation with high reduction ratios under varying feed conditions. It benefits continuous process and crusher control, therefore helping to perform high availability and reach optimal production levels of the desired product.

A single-cylinder cone crusher can process raw materials into small or oversize because the feed opening can be adjusted according to changes in feed size and flow rate. That is why the feed size of the material can be between ultra-coarse and ultra-fine.

The large feed opening can prevent clogging and allow the primary crusher to operate with a large opening port and closed side setting. The constant feed opening and wear compensation minimizes the need to adjust coarse crusher parameters during operation.

The adjustable stroke makes it easy to adjust the throughput to work in harmony with the rest of the crushing plant. The function creates proper throttle feed conditions and optimizes crusher settings to ensure maximum throughput for the desired product size.

When the cone crusher starts, the motor drives the belt pulley, and the coupling turns around, and then the strong driving force makes the concave move back and forth from the mantle surface installed in the adjusting sleeve.

The space between the crushing liner, the concave surface of the top frame, and the spindle cover are called the crushing chamber. Material is impacted, squeezed, bent, and is gradually crushed to the required product size in the chamber.

By moving the plunger position, the hydraulic cylinder can adjust the discharge setting between the housing and the concave to lower the spindle position when unbroken materials fall into the crusher cavity.

It is supported by self-aligning It is supported by a self-aligning bearing which is designed to cater to the eccentric movement generated by the swing shaft. The feed materials are crushed by an eccentric movement of the main shaft.

Concave is also known as the fixed cone because it is stationary in a single-cylinder cone crusher. It is made of new composite material with features of high anti-abrasion, high quality, reasonable prices, wide application field, etc.

The alloy steel pinion is mounted on the pinion drive shaft. The external motor pulley device provides power to the pinion shaft, and the pinion shaft rotates the main shaft through the pinion and crown gear device.

After long-term work of a single-cylinder cone crusher, the wearing parts will inevitably wear out. It is necessary to know what the wearing parts are, and then do some regular repair and replacement to stabilize production and avoid unexpected downtime.

Over the past 20 years, the crushing and grinding requirements of the mining industry have changed dramatically. In order to reduce costs, increase production and energy efficiency, more and more people tend to purchase cone crushers.

Crushing is the first step in the processing of ore. A single-cylinder cone crusher suits the specific production requirements of any type of ore because the machine can be adjusted by changing the chamber, eccentric stroke, counter shaft speed, and different control methods.

They produce high-quality aggregates and sub-base materials with beautiful cubic shapes. Due to its hydraulic release capability, unbreakable material can be safely removed from the chamber without affecting the function of the cone crusher.

Modern asphalt plants can make new asphalt mixes from 70% of the recycled material. In addition to fixed cone crushers, there are also mobile cone crushers with two types- portable ones and mobile ones. Both of them perform well when crushing materials in the city or other arduous environments, thus saving a lot of transportation costs.

Concrete waste always mixes with road cement blocks, waste materials, waste stones, and garbage. Traditional management plans, such as landfill, Incinerating, pilling up cause safety hazards, huge pollution to water, land, and air resources, occupying a large land area.

A single-cylinder cone crusher can ideally recycle concrete wastes and turn them into recycled aggregates (RCA). The RCA nowadays has become a "new pillar" in the field of road, construction, and new material, realizing its economic value.

cone crushers | mclanahan

A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the material gets smaller as it moves down through the wear liner as the opening in the cavity gets tighter. The crushed material is discharged at the bottom of the machine after they pass through the cavity.

A Cone Crusher will deliver a 4:1 to 6:1 reduction ratio. As we set the closed side setting tighter to create a finer output, we also reduce the volume or throughput capacity of the machine. Generally speaking, multiplying the closed side setting by two is a good guide to the top size of the gradation exiting the machine.

The technology that makes a MSP Cone Crusher outperform competitive cones on the market is the combination of all of the factors of performance i.e. balanced eccentric, higher speeds, fulcrum point position, and stroke. By using sound engineering with years of field testing a truly tried and tested new Cone Crusher has emerged.

A balanced eccentric coupled with a fulcrum point ideally placed over the crushing chamber yields highly effective compression crushing. This allows higher eccentric speeds to maximize performance without disruptive forces. The eccentric stroke is designed to work with the eccentric speed and fulcrum position to produce higher yields and minimize recirculating loads. The torque and resultant crushing forces are as effective as virtually any Cone Crusher on the market.

Spiral bevel gears provide the turning force to the eccentric. The spiral gear is mounted on a sturdy countershaft of the Cone Crusher, which rides in bronze bushings. The gears are precision cut for quiet operation. Misalignment problems are eliminated.

The MSP Cone Crusher features one of the largest volume displacements by a crusher head. When there is a large volume of material displaced this way, it means that more material is crushed in each cycle, more material can be fed to fill the larger void left when the crushing head recedes, and more material flows through the crusher due to the larger throughput and gyrating cycles allowing material to drop further. The benefits of high efficiency, greater crushing force and high capacity coupled with the durability the market expects are the reasons why this design is the best way to increase your productivity and profitability.

Sleeve bearings make removal and installation of the MSP Cone Crusher head and main shaft simple. The tapered main shaft fits into a large opening at the upper end of the tapered eccentric bushing. The shaft does not require precise alignment. It can be inserted from a vertical position and will self-align.

With the MSP Cone Crushers automatic hydraulic overload relief system, the crusher immediately opens in the event of an overload. This action reduces the crushing pressure, allowing the obstruction to pass through the chamber. After the chamber has been cleared, the hydraulic control system automatically returns the crusher to its original setting. Shock loads on the crusher are reduced for longer component life.

MSP Cone Crushers are built to make your operations run more smoothly and easily. Its simple and easy to read control panel provides you with the necessary information to properly run your crusher. For example, the MSP Cone Crusher shows you the exact cone setting to allow the operator to stay on top of a critical set point.

To enhance your Cone Crusher's life and maintain optimal crushing capacities, an automatic liner change reminder is included for your convenience. When the new mantle and liners are installed, the automated reminder is reset. As the crusher operates, the system will track production capacities and calculate the liner wear rate. When the cone liners reach the maximum wear point, it sends a flashing reminder to 'change cone' on the cone setting meter. After the wear parts are changed, simply reset the automated reminder system and continue efficient, reliable crushing.

The MSP Cone Crushers are built heavier than most competitive Cone Crushers. The extra weight means lower stress on the machine, which results in longer operational life. There is no question that the proper use of mass makes for more durable crushers. Additionally, a broad array of manganese liners is offered for each size MSP Cone. A unique and patented feature allows the Liners to fit without the use of any backing material. Improved Chamber matching with crusher feeds virtually eliminates any trial and error.

All these factors combine to give producers more effective compression crushing. This reduces liner wear, which reduces wear cost and allows higher yields, resulting in decreased overall cost per ton of finished product.

In the Symons principle, which is utilized by the MSP Cone Crusher, each cycle is timed so that the feed material and the upward thrust of the crushing head meet at the moment of maximum impact. The optimum speed of gyration and the large eccentric throw produce two important results: 1) the rapidly closing head catches the falling feed material and delivers the extremely high crushing force and 2) on the other side of the chamber the rapidly receding head allows material to fall freely to the next point of impact or exit the chamber. The combination of superior crushing force and free flow of material in the MSP Cone Crusher results in production levels that are unsurpassed and means lower power consumption per ton.

Ten years of testing went into the final combination of speed, stroke, and head angle to deliver the most efficient use of power. Greater efficiency delivers lower power consumption, reduced cost per ton, less maintenance and higher profits.

The power input imparted by the driven eccentric results in a bearing force in opposition to the crushing force at a point on the lower portion of the main shaft. The bearing force as it is transmitted to the main shaft provides the required moment to crush the rock. The distance between the bearing force and the fulcrum point is called the force arm. The longer the force arm, the greater the momentum, which produces a greater crushing force.

Crushing loads are distributed over a large spherical bearing. The socket liner keeps full contact with the crushing head ball and carries all of the vertical component and part of the horizontal. The long force arm, represented by the main shaft, reduces the load transmitted through the eccentric bushing.

Capacities and product gradations produced by Cone Crushers are affected by the method of feeding, characteristics of the material fed, speed of the machine, power applied, and other factors. Hardness, compressive strength, mineral content, grain structure, plasticity, size and shape of feed particles, moisture content, and other characteristics of the material also affect production capacities and gradations. Gradations and capacities are most often based on a typical, well-graded choke feed to the crusher. Well-graded feed is considered to be 90% to 100% passing the closed side feed opening, 40% to 60% passing the midpoint of the crushing chamber on the closed side (average of the closed side feed opening and closed side setting), and 0 to 10% passing the closed side setting. Choke feed is considered to be material located 360 degrees around the crushing head and approximately 6 above the mantle nut. Maximum feed size is the average of the open side feed opening and closed side feed opening.

Minimum closed side setting may vary depending on crushing conditions, the compressive strength of the material being crushed, and stage of reduction. The actual minimum closed side setting is that setting just before the bowl assembly lifts minutely against the factory recommended pressurized hydraulicrelief system.

Overall, industry acceptance of the Symons principle and performance, the McLanahan Cone Crusher works to deliver lower recirculating loads at higher tonnage rates with lower maintenance costs by combining:

A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 34 closed side setting, the maximum feed would be 6 x 34 or 4.5 inches. Reduction ratios of 8:1 may be possible in certain coarse crushing applications. Fine liner configurations typically have reduction ratios of 4:1 to 6:1.

The difference between the volume displaced by the crushing head when it is fully closed and fully open is called the displacement volume. A large displacement volume results in greater capacity because:

In order to maintain the maximum levels of capacity, gradation, and cubical product, a Cone Crusher must be choke-fed at all times. The best way to keep a choke-feed to the ConeCrusher is with a surge bin (or hopper) and feeder that are located prior to the crusher. Choke-feeding is almost impossible to achieve without a hopper and feeder.

There are a number of different criteria to consider when selecting the right chambers for your crushing needs. However, the one that must always be considered isthat you have a well-graded feed to the chamber. A well-graded feed is generally thought to be 90 to 100% passing the closed-side feed opening, 40 to 60% passing the midpoint, and 0 to 10% passing the closed-side setting.

One thing you should never do is place a new concave liner in a crusher with a worn mantleor place a new mantle in a crusher with a concave liner. Why? If you have properly selected the replacement component, you will change the complete profile of the Cone Crusher by mating new and worn components. The receiving opening will tend to close down, restricting the feed from entering the chamber and causing a reduction in tons per hour.

If the liner is wearing evenly throughout the chamber, you should consider changing out the manganese when it has worn down to about 1" (2.5 cm) thick at the bottom. At about 3/4" to 5/8" (1.9 to 1.6 cm) thick, the manganese will crack, causing the backing material to begin to disintegrate. This, in turn, will cause the liners to break loose. If this should happen, continued operation could destroy the seat on the support bowl or the head of the Cone Crusher.

McLanahan Symons Principle (MSP) Cone Crushers utilize a combination of improved factors of performance, which are enhanced by the Symons Principle of crushing, as well as the latest hydraulic features and electrical features that create a modern, efficient, reliable and durable Cone Crusher that ultimately leads to a faster ROI. MSP Cone Crushers are designed to make your operation run more smoothly and easily, as well as ensuring lower operating costs and minimal downtime so that MSP Cone Crushers are more frequently fully operational and processing optimal amounts of material.

Efficiency can be defined by the ratio of the work done by a machine to the energy supplied to it. To apply what this means to your crusher, in your reduction process you are producing exactly the sizes your market is demanding. In the past, quarries produced a range of single-size aggregate products up to 40 mm in size. However, the trend for highly specified aggregate has meant that products have become increasingly finer. Currently, many quarries do not produce significant quantities of aggregate coarser than 20 mm; it is not unusual for material coarser than 10 mm to be stockpiled for further crushing.
