The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:

A gyratory crusher was patented by Philetus W. Gates in 1881. Thomas A. Edison also designed a rock crusher to use in his own mining operation. Edison's design used giant rolls to function as a primary crusher. These machines never gained much popularity though because the gyratory and jaw crushers were more versatile.

Typical hard-rock crushers like jaw, gyratory and cones break rock by nipping the ore between a fixed/stationary and a moveable wear-resistant surface/liner. How much reduction each crushing stage is capable of infliction of rocks (reduction ratio) is driven by the angles between the 2 surfaces on each side and holding the rocks-to-be-crushed ...
