Roller crusher is a very old crushing equipment that appeared in 1806, and its structure is simple. It can crushers iron ore, Quartz Stone, rock gold, rock tantalum niobium ore, rock tin ore, rock tungsten ore, manganese ore, ilmenite ore, K-albite, limestone, river pebbles, copper ore, bauxite, barite, basalt, etc. Therefore the roll crusher is one of the most widely used crusher machines in the mining industry.
Rock Roll crusher is fine crusher equipment that similar to the hammer crusher. It can crush the compressive strength of less than 160 MPA of materials. Medium feed size, and adjustable discharge size. With the characteristic of low maintenance costs, low requirements for water, reliable performance, less power consumption, less dust, low noise and so on.
Stone roll crusher can be divided into single-roll, double-roll and multi-roll several types according to the number of rollers. According to the shape of the roll surface, have two kinds, smooth roll and tooth roll. The former is suitable for medium and fine crushing of medium hardness ores. While the latter is suitable for coarse and medium crushing of Brittle and soft ores.
The material falls between the two rollers through the feeding opening to squeezing and crushing. Then the finished material falls naturally. In the case of hard or no broken, the role can automatically retreat under the action of hydraulic cylinder or spring. The gap between the roller increase, and the hard or not broken material fall that can protect the machine from damage. The relative rotation of the two rollers have a certain gap, change the gap, you can control the product discharge granularity. Double-roll crusher is the use of a pair of opposite rotation of the Round Roller, four-roll crusher is the use of two pairs of opposite rotation of the Round Roller crushing operations.
3. If the feed material is not uniform along the length of the roller, the roller surface will not only wear quickly but also wear unevenly at every point. The annular groove appears will damage the normal crushing work, the particle size of a crushing product is not uniform. Therefore, in addition to the roller crusher used for coarse crushing, the medium and fine crushing roller crusher is usually equipped with a feeder machine to ensure continuous and uniform feeding. And the length of the feeder is equal to the length of the roller that makes the feed is uniform along the direction of the length of the roller.
4. Reasonable maintenance and proper operation can ensure long-term continuous work, reduce parking time. Only the normal management and daily check the normal working conditions, can prevent failure and ensure continuity of service.
(1) Pay attention to the fastening of the bolts of each component and tighten them immediately if found loose; (2) Before the work must start the crusher, wait for the speed in normal, then feed materials. The procedure is opposite when stopping; (3) Check the outlet regularly and remove the blockage if found; (4) Pay attention to check the wear degree of the wearing parts, at any time pay attention to the replacement of worn parts; (5) No overload and the electrical instruments keep under constant care; (6) The bearing oil should be timely, and do not make the bearing oil leakage; (7) Control the bearing temperature, the temperature rise should not be higher than the surrounding air 25 ~ 30 C; (8) Dust and other materials should be removed from the underframe plane of the movable device to prevent the movable bearing from moving on the underframe when the roller crusher encounters unbreakable materials, which may cause serious accidents.
The roller crusher composes of a roller wheel, roller supporting bearing, pressing and adjusting device and driving device. The crushing roller is the main working mechanism of the crusher, which is composed of shaft, wheel hub and roll cover. The wearing degree of roll top has a great influence on the working efficiency of roll crusher. Only when the roll top is in good condition, the crusher can get higher production capacity. Because of the importance of roller, it is of great significance to understand the factors affecting roller wear and correct repair of roller.
(1) The material is distributed evenly as far as possible to reduce the wear degree of the ring groove, and roller skin on the surface of the roller; (2) In the operation of the crusher, especially in the process of coarse crushing. Attent to the size of the ore blocks, to prevent the ore blocks from being too large. It will make severe vibration of the crusher, thus seriously wearing the roll skin; (3) The selection of roller skin with good wear resistance can reduce the wear degree of roller skin and prolong the service life of Roller; (4) the length of the feeder shall be the same as the length of the rollers to ensure uniform feeding along the length of the rollers. In addition, in order to continuously feed the ore, the speed of the feeder should be 1-3 times faster than the speed of the stick; (5) Often check the size of the broken product and move one of the rollers along the axis for a certain period of time, the distance is about 1 / 3 of the size of the ore.
Double Roll crushers are the most common type of roll crushers. The crusher machine uses two opposite rotating rollers to crush the material. It is composed of an electric motor, support, a fixed roller, a movable roller, a safety spring, etc. With smooth and serrated surfaces. The bearings of the active rollers can move along the frame which supported by strong safety springs. The bearing will remove out and spit out the article if the feed material is very hard. The roll surface has smooth and sawtooth.
Two Roll surface is smooth that mainly play the role of extrusion grinding crushing on the material. This equipment often uses for clay, coal, clinker and limestone and other materials in the fine crushing work. The roller surface with the sawtooth of the two rollers. The machine mainly plays the role of cracking and tearing. The equipment is mainly to complete the bulk crushing of materials. The smooth surface of one roll and the sawtooth of the other roll that mainly to play the role of extrusion, bending and grinding on the material. This type of double-roller crusher mainly uses to crushing clay and coal.

Why Use Phoenix for Your Plant Dismantling & Plant Relocation Needs A Common Plant Liquidation Scenario Your company has made the tough decision to close a plant. This plant was running for years, and the company paid a lot to have it built, paid everyones salaries, and maintained or even modernized all of the production assets over the plants life but the plant needs to be sold off for one reason or another. Your company has called upon you to recover as much dollar as you can to help keep the organization alive, and better yet, healthy, in what is a constant battle in the marketplace. Youve either: Have spent months, maybe even years trying to find a buyer that would operate the plant in place, without any success, while the plants assets lose value every passing day. Or, you cant sell it to another company, as you are one of the few suppliers of the product the plant makes, and you dont want to create a competitor, or improve a competitors position. Or, the plant is on leased propert
Hydrogenation: Major Applications Hydrogenation is a billion-dollar industry. Hydrogenating means to add hydrogen to something. According to Haldor Topsoe, hydrogenation comprises 48% of total hydrogen consumption, 44% of which is for hydrocracking and hydrotreating in refineries , and 4% for hydrogenation of unsaturated hydrocarbons (including hardening of edible oil) and of aromatics, hydrogenation of aldehydes and ketones (for instance oxo-products), and hydrogenation of nitrobezene (for manufacture of aniline). Hydrocracking & Hydrotreating Industrially, hydrotreating and hydrocracking are performed in down flow trickle bed reactors, where the gas and the liquid feed are sent concurrently through a fixed bed plug flow reactor. Although the flow pattern in the reactor can be reasonably approximated, the observed kinetics in such a trickle bed reactor are quite often affected by minor unplanned oscillations in the flow. How the gas and liquid collide and mix together affects the end prod
Thermoplastics A Focus on Polyethylene & Polypropylene Thermoplastics are a class of polymers, that with the application of heat, can be softened and melted, and can be processed either in the heat-softened state (e.g. by thermoforming) or in the liquid state (e.g. by extrusion and injection molding). Over 70% of the plastics used in the world are thermoplastics, and the two most commonly used thermoplastics are both olefins, compound made up of hydrogen and carbon that contains one or more pairs of carbon atoms linked by a double bond. These two olefins are polyethylene and polypropylene. Polyethylene Polyethylene is a tough, light, flexible synthetic resin made by polymerizing ethylene, chiefly used for plastic bags, food containers, and other packaging. It may be of low density or high density depending upon the process used in its manufacturing. It is resistant to moisture and most of the chemicals. It can be heat sealed and is flexible at room temperature (and low temperature), and in additional to its material properties,
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.
