Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.
This vibration is usually, but not necessarily, in a vertical plane. Vibration mills are similar to ball mills in that particles of the materials are crushed between porcelain or metal balls and the mill body. Drugs and excipients are readily ground to less than 5 μm, the grinding time being considerably less than is required in normal ball ...
