Gyratory and Cone Crusher
The product size from a primary crusher is limited by the possible reduction ratio, which normally is around 10:1. The feed size to a primary crusher from the mines could be 1–1.5 m; thus, the maximum product size possible is 10–15 cm which is normally too large for down stream processing for mineral liberation.
