The double-roll crusher is mainly suitable for coarse and intermediate crushing of brittle bulk materials in mining, metallurgy, chemical industry, coal mine and other industries. Especially in the coal industry, when using this machine to crush raw coal, it can be directly crushed as long as it has undergone iron removal, impurity removal, …
1. Introduction. The double-roll crusher—a crushing device in which breakage occurs between a pair of rolls that rotate in opposite directions—is used for crushing particles into a size range of 1–50 mm.The minerals of rock particles placed between the rolls are nipped and then crushed as they pass between the rolls.
In coarse comminution, double roll crushers (DRC) are used for the size reduction of blasted materials and in secondary comminution. In the primary crushing stage, DRC with toothed rolls are of particular importance. In contrast to smooth rolls, these offer improved nip conditions so that larger particles can be nipped, and crushed.

Crushing cases of the two crushers Manufactured sand made by roll crusher in Indonesia. The video shows the double roller crusher is turning small-sized stones into manufactured sand. There is a certain gap between the two counter-rotating rollers. Changing the gap can control the product size, shapes, and fineness modulus.
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 ...

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 material than Roll Sizers and can take in larger feed sizes making it the optimal primary crusher for soft and medium hard rocks.
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 …

Double Roll Crushers 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. …
Shumar Engineering (Pty) Ltd Our unique Double Roll crushing principle and segment design has resulted in improved plant efficiencies as well as increased profitability for our clients by reducing the amount of fines generated through the crushing process. Shumar Engineering's revolutionary Odeca scalping screens were first developed and marketed …
Double Roll Crushers feature two rotating roll shafts that crush material between the teeth and roll bodies. These types of Roll Crushers produce a cubical product with minimal fines generation, and can handle higher capacities. In the correct application, Triple and Quad Roll Crushers are capable of performing both primary and secondary stages ...
DOUBLE ROLL CRUSHER DR13 Features Solution for medium-hard rock as well as sticky and soft materials (coal, limestone, clay, salt, etc.) Weld-on hard-faced crushing teeth with various configurations for most difficult applications Integrated flywheel equalizing torque peaks, thus reducing required motor power Permanent parallel position of crushing rolls …
Tooth roll crusher, also known as double roll crusher, is a versatile equipment used for material reduction in various industries. It consists of two cylindrical rolls that rotate in opposite directions, with each roll containing teeth that interlock with the teeth on the opposite roll. As the material is fed into the crusher, it gets crushed ...
The theoretical efficiency of the double roll crusher when crushing limestone was 60% while that of kaolin was 80%. A developing nation like Nigeria, with huge deposit of different solid minerals and rocks, needs to explore the processing of these solid minerals to reduce dependence on petroleum. The old ways of stone crushing by …
As a result, the forces acting in a double roll crusher could be much higher, at least locally, as one would expect for normal single particle comminution. This should …
Double Roll Crushers DRC Series Roll Crusher The DRC series roller crusher is widely used in tertiary crushing with the material feeding size less than 30mm and the product size 1 - 10mm of artificial sand making (cobblestone and construction waste), mineral separation (iron ore and quartz stone) and grinding material (ceramic industry).
Binder+Co Double roll crusher. An optimum grain size of 10 to 50 mm is crucial for sensor-based sorting of cullet since a higher content of fines (0-10 mm) would have an unfavourable effect on sorting performance. In the form of the double roll crusher, Binder+Co has created the ideal prerequisite for the subsequent sorting of waste glass.
Although its brief period of popularity passed some thirty-odd years since, and only a few sets were installed before interest reverted to other types, the high-speed double roll crusher developed by Thomas A. Edison shortly before the end of the last century warrants a place in any discussion-of crushing equipment. In 1960, the largest …
