Double Roll Crushers McLanahan. Double Roll Crushers. 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.
Wear Resistant Parts: the double roll crusher roller is equipped with a replacement wear resistant lining board with wear resistant material, with long service time; 3. The output particle size can be adjusted less than 150mm, automatically adjusted by adjusting the clearance of the roller, to meet the different crushing requirements of customers;
To represent the particle behaviors and to predict the product size distributions of coal breakage products by a double-roll crusher, a new combined breakage–agglomeration model has been
Double Roll Crusher is short for roll crusher or roll crusher. The roll crusher has simple structure and few over crushing phenomena. The tooth shape, size and arrangement on the roll surface can be changed with the material properties, and it can be used for medium and fine crushing of medium hard and soft ores.

Product particle size regulated by precise hydraulic setting of the roll gap; Opening of the gap between the crushing rolls in case of overload (e.g. caused by an unbreakable foreign object) within milliseconds to let that piece pass thus avoiding a shut-down; Features. Very long live-time due to the extremely hard chromium alloyed roll tires
As the term "primary" implies, primary crushers are used in the first stage of any size reduction cycle. Generally gyratory crushers, jaw crushers, high speed double roll crushers, low speed sizers, impactors and hammer mills are used as primary crushers. In the
Roll Crusher. For a given reduction ratio, single-roll crushers are capable of reducing ROM material to a product with a top size in the range of 200–18 mm in a single pass, depending upon the top size of the feed coal. Double-roll crushers consist of two rolls that rotate in opposite directions.
Double roll crusher is mainly composed of 2 rollers, driving, pressing & adjusting devices and roller support bearings. One roller is fixed and the other is adjustable. The gaps between the two rollers decide the discharge particle size.

For rolls that have equal radii and length, tangents drawn at the point of contact of the particle
Mode of operation. Combination of the characteristic of the Double Roll Crusher with the performance of the Sizer. Crushing of feed material by teeth of the two counter-rotating rolls. Successive comminution of larger lumps. Product particle size regulated by precise setting of the roll gap. Opening of the gap between the crushing rolls in case
Working Principle of Double roll crusher. A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.
Double Roll Crushers are designed for single-pass size reduction of medium-hard to hard materials such as rock or ore to a nominal minus 10 mesh. Topsize is approximately 13mm and final fineness typically passes a No. 10 (2mm) opening, depending on material type.
Roll Crusher Working Principle. 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

Overview Roll crusher is also named double-roll crusher,roll-type crusher.It is usually used to crush the raw materials such as coal , coal gangue, coke , limestone, sulfur ore, phosphate rock and etc, which are usually crushed in middle or fine size by the way of roll extrusion .Roll crusher is widely used in the fields of ore dressing, chemical, cement, refractories, grinding materials
DOUBLE ROLL CRUSHER Working Principle and Structure of Double Roller Crusher 1.this series of roll crusher is mainly formed by the roller, roller support bearing, compression and adjusting device, drive components etc. 2.the adjustment of the particle size: between the two rollers equipped with adjustment device like pads or wedge.The wedge

A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the Rolls. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. 10/18/201514ch42, 14ch24 4

The application of Double Roll Crusher. Double roll crushers are particularly suitable for medium and fine grinding processes, demanding a strictly defined portion of fine grain and a low dust content. Raw materials, secondary raw materials and by-products such as coke duff, coal, rock, fireclay,fertilizer, salt, glass and similar products.
