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 pebblesSteel Ball Mills & Lined Ball Mills Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s The basic construction of a ball mill is a cylindrical container with journals at its axis The cylinder is filled with grinding media (ceramic or metallic balls or rodsBall Mills | Ball Mill | Ball Milling Orbis Machinery
