2012-11-26 · The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.
Get DetailsEach mill manufacturer recommends certain grinding media type for mill operation under certain conditions: the crushed material parameters, the mill’s performance, the raw materials particle size in the mill’s “feed”, and the required grinding fineness (finished class content). – Past experience of a ball mill.
