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

The milling jar is half filled with grinding media or balls from " to 1" and as the mill rotates the solids are trapped between the ball and are milled down to as little as 1 micron by the cascading and tumbling action of the ball charge Milling jars available in ceramic carbon steel stainless steel rubber lined or polyurethane lined
