The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc., as well as for ore dressing of ferrous and non ferrous metals. The ball mill can grind ores and other materials, wet or dry.
Ball Mill amp; Discharge Trommel. Grate Discharge Ball Mill . For closed grinding circuits producing typical ball mill products, indirect and direct on line measurements of the product size are available. The indirect means are those which assume that the product size is relatively constant when the feed condition to the classifying unit and the operating conditions in the c

The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 20 75 mm. The biggest size is chosen when the mill is used as a primary grinding mill.
