ABSTRACT: A ball mill is the vital component in industries viz. mineral dressing, ore processing, fertilizers, food and diary, pharmaceuticals balls. The common classifiion of a ball mill is any type of mill in which mild steel or iron balls are used. In most cases, the cylinder of such a mill is made of alloy steel, or with some

Autogenous or autogenic mills are so-called due to the self-grinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in
