The comminution of smaller coarse particles is done by Cone, roll. Hammer crushers and rotary breakers. Grinding is conducted in mills. There are three grinding stages, coarse grinding (hundreds of microns), fine (tens of mictons) and ultrafine grinding (<10 microns). Tumbling mills, rotary breakers, and pendulum mills are mostely used.
