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.

Grinding intensity had an effect only on the meal diets with higher ADFI for the coarsely ground meal. Pigs fed the finely ground meal had a lower (P < 0.001) ADG than the other 3 diets. Feed efficiency was influenced only by the feed form (P < 0.001) and not by the grinding intensity. Pelleting the feed gave rise to a higher G:F.
Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.
