Agitated Media Mills

Agitated Media Mills are media mills that employ an agitated (or stirred) grinding media action for grinding of the ultrafine particles. Many types of metallic or ceramic grinding media are available for the fine grinding of a particular mineral, metal or chemical power. They are dry airswept media mill used for the production of fine powders typically below 45 microns. The mill is available in sizes of 20 HP to 2000 HP.

This stirred media mill concept is unique as the feed material is fed pneumatically into the mill. The particles to be ground are airswept across an agitated bed of grinding media and exit the mill in an airstream directly to a high efficiency air classifier, where on size particles are removed and oversize particles rejected and returned to the pearl mill in the feed conveying system. The grinding media does not discharge from the mill.
