Ball Mill Application and Design - Paul O. Abbe

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. In the case of wet...
