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.

In stirred-medium mills, the stirrers set the contents of the mixing chamber in motion, causing intensive collisions between the grinding medium and the ore particles and between the ore particles themselves. The grinding action is by attrition and abrasion, in which very fine particles are chipped from the surfaces of larger particles, rather than impact breakage.
