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 pebblesDrum Mill TM 300 The TM 300 Drum Mill is used for the preparation of granules and powders The grinding process is performed either in dry or wet conditions The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module A sufficient number of balls or rods is required for an effective grinding processRetsch : Milling : Ball Mills : TM 300
