Ball Mill. Ball mill machine is widely applied in the industries, such as cement, silicate product, refractory, fertilizer, mineral processing of ferrous and nonferrous metal and glass ceramic, etc. It is mainly used to make dry or wet powder grinding of various ores and other grindable materials. Working Principle Of Ball Mill:
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw 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.
