In the quarry, crushing is handled in four potential stages: primary, secondary, tertiary and quaternary. The reduction of aggregates is spread over these stages to better control the product size and quality, while minimizing waste.
The packing density that develops within crushers as the aggregates pass through affect the energy required to crush rock and the characteristics of the products (fines content and particle shape). The evolution of packing density is determined by choking conditions and the geometry of the crusher. The average normal contact force per particle
Rock from the quarry face is fed into the top of the crusher and crushed rock falls out of the bottom of the jaws. The size of the crushed stone which passes through the jaws is partly governed by the gap set at the bottom of the jaws, though larger size rocks can pass through if the rock being crushed is slabby or elongate in shape. Large scale gyratory crushers can also be used.

Production drops off dramatically when producing smaller materials. Even with the new high-speed, high-throw cones. Cones can vary from 60 percent to over 80 percent efficiency. Crusher efficiency has a huge influence on productivity. As an example, let's compare two cones with 300 tph capacity, one at 60 percent efficient and the other at 80 percent efficient.
