Ball mill - Wikipedia

A ball mill , a type of grinder, is a cylindrical device used in grinding or mixing materials like ores, chemicals, ceramic Seven Trust materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.Working & 183; Appli ions & 183; Description & 183; Advantages of the ball mill & 183; Varieties

What Is a Ball Mill? - Monroe Engineering

Mar 10, 2020& 0183;& 32;How a Ball Mill Works. Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse …
