The double-roll crushers, in contrast, are equipped with two rotating cylinders that compress the material between them. The double-roll crushers can be further divided into the smooth-roll crushers that have the smooth cylinder surfaces and toothed-roll crushers that have toothed or corrugated surfaces to provide the better grip …
Types of Roll Crushers. There are 4 major types of roll crushers used in the construction industry: Single Roll Crushers. Single-roll crushers consist of a wedge-shaped crushing area. The materials are crushed by the shear pressure and stress of the crushing area. These crushing machines are used for compressing soft to medium-hard …
The double-roll crusher model, first proposed by Austin et al. [15] and lately refined by Austin et al. [16], is based on the following assumptions: a) breakage of each size particle occurs independently of the other sizes, b) provided the roll diameter is large enough compared with the feed size and gap, the product size distribution depends ...
Double-Roll-Crushers are used for the crushing or medium-hard rock as well as for sticky and soft materials, i.e. clay, marl, limestone and similar raw materials. Sticky and soft …
The double roller crusher with smooth rollers DRC 200x125 is designed to crush brittle materials of various strengths. The operational principle of the double roller crusher is based on simultaneous compressive and shear strains between rollers rotating in opposite directions. The grain size of the crushed material
Crushers are one of the main equipment used for reducing size in metallurgical, mechanical, and other similar industries. They exist in various sizes and capacities which range from 30 tons/hr. to ...

The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and higher. It is less sensitive to wet and sticky material than RollSizers and can take in larger feed sizes, making it the optimal primary crusher for soft and medium hard rocks. Technical specification Application data
Crushers for Bulk Materials Crushers and breakers are used to reduce size of mined and quarried material for further ... Generally gyratory crushers, jaw crushers, high speed double roll crushers, low speed sizers, impactors and hammer mills are used as primary crushers. In the secondary and subsequent stages, the material is further reduced ...
Roll Crusher Introduction . Roll Crusher is mainly applied in mine, cement, metallurgy, chemical, electric power, coal and other industries, especially for crushing various materials with medium hardness. And it has the features of simple structure and convenient operation and maintenance. Main Technical Parameters
The Double Roll Crusher crushes a wide range of material types reaching compressive strengths of up to 150 MPa and even above. It is less sensitive to wet and sticky …
In single-roll crushers, a piece of material is fed into the gap between a roll and a solid, stationary plate. During the operation a complex stress state is generated in the destructed material.
Comminution between counter-rotating rolls is a well-established principle. In coarse comminution, double roll crushers (DRC) are used for the size reduction of …

Processing of bulk materials used in metallurgical industry to obtain necessary grades of size requires application of crushing machines, including a single …
FAM designed crushers are used for crushing minerals, raw materials and other bulk commodities. The types of crushing machines are distinguished by their working principles: by pressure, impact, hammer, or shear. In contrast to mills, crushers process the feed materials into grain sizes from coarse to medium granulation.
Double Roller Crushers are Roller Crushers that are widely used for secondary and fine crushing in the industry of mining, building materials, chemical industry, and metallurgy and so on. It can crush materials in middle hardness such as rocks, ore, coke, lump coal, slag, mineral slag, cement clinker, fireproof materials, and so on.
The double-toothed roll crusher is also called the toothed roller crusher. These crushers are widely used for coarse and intermediate crushing of brittle block materials in mining, metallurgy, building materials, refractory materials, chemical industry, coal, and building construction materials. In the coal industry, the raw coal can …
Experimental data on extensive pilot-scale investigations with a DRC comminuting limestone, andesite and diabase are presented.. Double roll crushers (DRC) comminute rock and ore up to very high strength with little impact of feed material UCS on mass throughput.. Feed particle size distribution has a substantial impact on DRC mass …
Progress in Roll-Crushing. BY C. Q. Payne, New York, N. Y. On the right, a Roll Crushers is shown in a sectional elevation of the A-C single-roll crusher while here below is a cutaway view of the machine, with hopper and part of the near side frame removed to show the crushing chamber. The moving elements of the machine consist of the roll, with its …
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.
