Roll Crusher - an overview | ScienceDirect Topics

Roll crushers apply shear or compression to the material that is going to be reduced in size. This action occurs between two hardened surfaces. The speed and diameter of the rolls, the desired capacity, and the feed and product size distribution are all critical in the proper sizing and operation of this type of machine.
