The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition. Ball mills have the advantage of being self-contained so operators are not exposed to the product being milled. Ball mills cab be used equally well for wet or dry grinding.

Wet & Dry Grinding Circuit Design. The type of mill for a particular grind and the circuit in which it is to be used must be considered simultaneously. Circuits are divided into two broad classifications, open and closed. In open circuit, the material is fed into the mill at a rate calculated to produce the correct finished product in one pass ...
