Common Feed arrangement problems — Sandvik Mining and

Description: Segregation is when coarse and fine particles enter different parts of the chamber. Typically, smaller particles will accumulate at the bottom of the conveyor and large particles on the top. When fed into the crushing chamber the large particles accumulate on one side of the feed hopper and the small particles on the other side.

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
