Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be
Get PriceThe implicit assumptions and interconnections between three methods of sizing ball mills are discussed. The first method is the rate-of-production analysis in which the output of a test mill is described by the rate of production of material of some desired percentage less than a set size per unit of mill volume; this rate is.
