Crushing Principles of Mechanical Crushing

2016-1-12  Crusher Operation • Relation between Feed size and Shape – The greater reduction ratio the worse particle shape. – Inter particle breakage improves shape. When crushing a bed of material weaker particles will break first. Flaky or elongated particles are weaker then round. – Breaking round particles gives flaky material.

Grinding Mill - Eastman Rock Crusher

Crushers are used to reduce particle size enough so that the material can be processed into finer particles like powders in a grinder. So, a typical processing line at a mine might consist of a crusher followed by a SAG mill or a ball mill. In this context, grinding mills like ball mills are considered grinders rather than crushers.
