9.2.2 Roll crushers 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.
The working principle of the roll crusher depends on the mutual compression of the cylinders at high speed and low rotating rate. So, the roll crusher is most effective for smaller production capacity and when is used for crushing minerals, especially if the minerals are not too rough or abrasive. Share this:
