Types of Rock Crushers | Quarry Crushing Equipment | Kemper
Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.

Rock Crushing Process in Mining
First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher "breaks it and the fine material produced will drop through the gap between the mantle and the liner as it opens. The coarse material that can't fall through will remain to be crushed with the next gyration.
