Ball mills rotate around a horizontal axis, partially filled with the material to be . time, optimum media load, optimum material load, and optimum milling speed.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing . A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either . pigments, and feldspar for pottery. Grinding can be carried out either wet or dry but the former is performed at low speed.
