Roller crushers consist of two rolls that rotate in opposite directions to crush material placed between them. The gap between the rolls can be adjusted and determines the size of crushed material fragments. To effectively crush material, the angle of capture between the rolls must be less than the angle of friction between the material and rolls. The document provides formulas …

The typical throughput on every modern crusher is a 6 to 1 reduction ratio, gyrator, jaw, and roll. The exception is a hammer mill. A hammer mill will reduce to finer sizes due to no "nip" angle associated with the others. Check out Mount Baker Mining and Milling, Or if you have a steel shop, make your own.

The material is fed at a uniform rate along the total width of the drums. The nip angle is the important parameter here for the crushing to take place. The nip angle of the feed material is further dependent on the coefficient of internal friction of the material which is essential for the material to pass through the drums and get crushed.
