Rolls were easy to manufacture, to install and to operate in a wide range of applications. A robust and reliable design, low machine height and an excellent ratio of capacity versus machine mass make double-roll crushers (DRC) still today the preferred choice for many soft to medium-hard rock applications in quarries and ore mines.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

The reason is that P (A)+P (B) P ( A) + P ( B) double counts outcomes where A A and B B both happen. For example, suppose A A is “⚅ on 1st roll” and B B is “⚅ on 2nd roll”. Then, it is not hard to see that the event A or B A or B happens on 11 out of 36 outcomes, so P (A or B) = 11 36 ≠ 12 36 = 1 6 + 1 6 = P (A) +P (B).

Double Roll Crushers. Double roll crushers reduce primarily through compression, although some shear is obtained with toothed rolls. Rolls for these crushers come in combinations of smooth, corrugated, and toothed designs. Double Roll Crushers produce a finer product at lower reduction ratios and capacities.

Introduction. Roll crushers consist of two or more adjacent rolls placed parallel to each other and rotated in opposite directions. Single roll crushers are also available which rotate a single roll against a fixed breaker plate. Mineral or rock particles placed between the rolls are nipped and then crushed as they pass between the rolls.
