Roll crushers, or crushing rolls, or double roller crushers, are still used in some mills, although they have been replaced in most installations by cone crushers. They still have a useful application in handling friable, sticky, frozen, and less abrasive feeds, such as limestone, coal, chalk, gypsum, phosphate, and soft iron ores.

The mode of operation of roll crushers is extremely simple, the standard spring rolls consisting of two horizontal cylinders which revolve towards each other. The set is determined by shims which cause the spring-loaded roll to be held back from the solidly mounted roll.

Smooth-surfaced rolls are usually used for fine crushing, whereas coarse crushing is often performed in rolls having corrugated surfaces, or with stub teeth arranged to present a chequered surface pattern. Sledging or slugger rolls have a series of intermeshing teeth, or slugs, protruding from the roll surfaces. These dig into the rock so that the action is a combination of compression and ripping, and large pieces in relation to the roll diameter can be handled. Their main application is in the coarse crushing of soft or sticky iron ores, friable limestone, coal, etc., rolls of 1 m diameter being used to crush material of top size 400 mm.

Wear on the roll surfaces is very high and they often have a manganese steel roll, which can be replaced when they are worn out. The feed must be spread uniformly over the whole width of the rolls in order to give even wear. One simple method is to use a flat feed belt of the same width as the rolls. Since there is no provision for the swelling of broken ore in the crushing chamber, roll crushers must be starvation fed if they are to be prevented from choking. Although the floating roll should only yield to an uncrushable body, choked crushing causes so much pressure that the springs are continually on the work during crushing, and some oversize escapes. Rolls should therefore be used in closed circuit with screens. Choked crushing also causes interparticle comminution, which leads to the production of material finer than the set of the crusher.

There are two types of roller crusher, smooth roller and tooth roller. Smooth roller crusher crushes materials mainly by extrusion of two rollers, meanwhile also has function of grinding, it is good for medium and fine crushing of medium hardness materials. While tooth crusher crushes material mainly by chopping, also has function of grinding, good for coarse and medium crushing of fragile and soft rocks.

Double roller crusher model is named by roller diameter and length, for example model 2PG0640, 2 means two roller, P stands for crusher, G stands for smooth roller, 06 stands for roller diameter 600mm, 40 stands for roller length 400mm. Similarly, 2PGC500x750, C stands for tooth roller.

differences between double roller crusher and toothed roller crusher | china first engineering technology co.,ltd

The toothed roller crusher is a new type of equipment developed on the basis of double roller crushers. Both are a type of roller crusher and both use rollers to squeeze the materials to crush the materials. They are commonly used crushing equipment in the mining industry. But what is the difference between them? Today we will explain to you the differences between double roller crusher and toothed roller crusher.

The double roller crusher is widely used in metallurgy, building materials, refractory materials and other industrial sectors to crush medium and high hardness materials. It has the characteristics of low noise, less dust, reliable performance and convenient maintenance. The toothed roller crusher is suitable for coal, metallurgy, mining, chemical, building materials and other industries, and is more suitable for the crushing of raw coal in large coal mines or coal preparation plants. It has the advantages of small size, large crushing ratio, low noise, simple structure, convenient maintenance, high productivity, uniform finished product size, low over-crushing rate, convenient maintenance, sensitive overload protection, safety and reliability.

The double roller crusher adopts the working principle of squeezing of the rollers with low speed and high pressure. The roller crusher contains two smooth rollers. During production, the material falls vertically from the upper part of the crusher into the crushing cavity, and the strong pressure generated between the two rollers squeezes each other to broken the material.

The toothed roller crusher can be divided into two types: double-toothed roller crusher and four-toothed roller crusher. When the crusher is in production, the material flow enters the two-roller V-shaped crushing cavity and will collide with the high-speed rotating toothed rollers. And the surface of the roller is covered with tooth-shaped crushing bodies, and the material is split by rotating and squeezing when the machine is working, so as to achieve the purpose of crushing.

The double roller crusher is usually composed of body, base, fixed roller, movable roller, transmission device, and safety device. The gear transmission device is mainly composed of fixed roller, movable roller, transmission shaft, body, chassis, cover, and Long gear cover and other parts. The toothed roller crusher is composed of active toothed roller, reducer, hydraulic coupling, motor, electric oil supply pump, passive toothed roller, arcuate toothed plate, side toothed plate, side toothed plate seat, lower body, and speed measuring device.

The double roller crusher uses the method of squeezing friction to crush the material with finer particle size. While the toothed roller crusher uses toothed rollers to break the material, and the material is granular with relatively coarse particle size.

double roll crushers | mclanahan

Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals, such as ROM coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, shale and wet, sticky feeds. They are one of the most widely used crushers in the mining industry and have numerous advantages, such as high capacity, low headroom, low horsepower, the ability to handle wet, sticky feeds and the ability to produce a cubical product with minimum fines generation. Roll diameters and widths are dictated by the feed size, product size and capacity. The rule of thumb for the Double Roll Crushers ratio of reduction is 4:1.

The simplified design gives these units excellent reliability and requires very little maintenance. The crushers are designed with built-in tramp relief that allows for the passing of uncrushable objects while remaining in continuous operation and returning to the initial product setting. With a variety of roll surface designs, this crusher is capable of producing a much finer product. Since each machine is custom engineered, roll elements and tooth patterns are selected depending on each unique application.

McLanahan Double Roll Crushers feature slower roll speeds and a larger surface area to add prolonged life to the crushing elements, resulting in less maintenance downtime and decreasing your cost per ton. Double Roll Crushers generate minimum fines while producing a cubical product.

McLanahan Double Roll Crushers are designed for safety and many years of rugged operation. Effective tramp protection against non-crushable material is provided by an automatic spring-and-toggle system. This allows a movable roll to open, pass the material and return to its original setting for continued operation. Hydraulic product size adjustment allows producers to adjust for changes in product size requirements or to compensate for roll wear.

Operating Double Roll Crushers is quite simple. Whether it is a single or dual drive arrangement, the rolls are powered by electric motors and V-belt drive configurations, resulting in reliable and quiet operation. If it is a single drive arrangement, power is transferred from the driven roll to the non-driven opposing roll by an interstage V-belt drive. If it is a dual drive configuration, each roll is powered independently through a motor and V-belt drive.

During normal operation, the material is fed between the crushing rolls. A combination of compression and shear forces created between the opposing rolls reduce the feed material to the desired product size while producing a cubicle product with minimum fines.

McLanahans mechanical tramp relief systems employ a spring-and-toggle mechanism that activates whenever an uncrushable object enters the crushing chamber. Once an excessive force is applied to the movable roll, the toggles break open to allow the uncrushable item to pass. The high torsion springs then close the toggles, returning the movable roll to the previous setting. The crusher continues to operate uninterrupted.

When an uncrushable object, such as metal, roof bolts/timbers, etc., enters the crusher and the force necessary to crush this material is greater than the crushing forces of the crusher, the crusher allows the moveable roll to open and pass the tramp material and then return to its previous setting and remain in operation.

Depending on the customers desired product size and fines consideration, Mineral Sizers or Hammermills could be considered. The reasons people would consider a Roll Crusher over these alternative technologies include lower power requirements, less fines generation and costs.

Black Diamond Double Roll Crushers are the most versatile and popular model of McLanahan Double Roll Crushers. Ideal for secondary and tertiary crushing applications where product requirements drop down to (6mm), Black Diamond Double Roll Crushers are most commonly used to crush clean coal or friable materials with little or no hard refuse. They are available with single or dual V-belt drive.

Heavy-Duty Double Roll Crushers are ideal for the primary, secondary and tertiary crushing of limestone, gypsum, ROM coal, etc. where higher compressive strength material is anticipated. Due to the V-belt drive design, a lower horsepower is required compared to other crushers designed for the same applications.

Shalemaster Double Roll Crushers are driven mechanically with V-belt drives and gear reducers. They offer the same durability as other McLanahan Double Roll Crushers but are designed to handle wet, sticky feeds such as soft shale, kaolin and clay. The Shalemasters special tooth design and differential roll speeds provide optimum performance against plugging and other problems often associated with handling sticky materials.

Typically used as secondary or tertiary crushers, McLanahan Double Roll Crushers provide a 4:1 reduction ratio and can be used following other McLanahan equipment, such as Feeder-Breakers, Rotary Breakers, primary DDC-Sizers, or Single Roll Crushers, when further reduction of primary crushed material is required. Each Double Roll Crusher is selected and engineered for its specific application, thus roll elements and tooth patterns are selected based on the customers unique applications and designed to produce a cubical product with minimal fines.
