Ball mill Wikipedia
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 pebblesThe smaller ore will go on to the ball grinding mills where they will be further ground down The larger ore will be routed to a pebble crusher to reduce the size to 13 cm (½ in) and will return to the SAG mill stage The ball mill product is pumped to cyclones which separate out the coarse material with the fine oreWhat Is Mineral Processing in Mining?
