A ball mill is a type of grinder consisting of a rotating cylindrical shell partially filled with grinding balls, working on the principle of impact and attrition as the balls drop and tumble while the shell turns. In ceramics it is used to grind materials such as feldspar and flint into fine powder for use in pottery bodies and glazes, grinding either wet or dry, with wet milling performed at low speed. Ball mills are reported to have been used for grinding flint for pottery as early as 1870.
