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).

Typically designed for primary crushing, McLanahan Single Roll Crushers efficiently crush material at a 6:1 crushing ratio. . They can continually withstand heavy-impact applications. Single Roll Crushers reduce large size particles in the feed to a medium size, while producing a low percentage of fines.

Schematic Diagram of Roll Crushers. Some rollers are toothed. The shape of the teeth is generally pyramidal. The roll surfaces play an important part in the process of nipping a particle and then dragging it between the rolls. The corrugated and ribbed surfaces offer better friction and nip than smooth surfaced rolls.

Roll crushers vs hammer crushers Both are used in the secondary or tertiary crushing process but still have many differences. Roll crushers reduce material by force generated from two relatively rotating drums. First, the material enters the feed opening along with the high-speed rotating roller drums, then it got crushed by strong …

The method proposed in [6] allowed increasing the accuracy of determining the crushing force, and, accordingly, the drive power of roll crushers by 1.2–3.5 times, depending on the coefficient of friction of the crushed material over the material of the roll bandage by considering the distribution function of the material over the surface of ...

Tooth roll crushers are more efficient in crushing hard materials, while smooth roll crushers are better for crushing soft materials. Q: What is the capacity of a tooth roll crusher? A: The capacity of a tooth roll crusher depends on several factors, including the material being crushed, the gap between rolls, and the speed of the rolls.

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 and refined for proper size and shape, mostly based on specifications. Most secondary crushers are cone crushers and
