Working principle:
Autogenous mill, also called no-medium mill. the characteristic is that the grinding medium is the ore material itself. the ore material is continuous fed in the rotating horizontal drum from one side, under the rotation of drum lining, getting pulverized effect from the collision and grind of ore itself, at last the fine mine product is forced discharged by wind(dry type) or chute board(wet type).
