## Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotating about its axis The axis of theBALL MILLS 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 2075 mm The biggest size is chosen when the mill is used as a primary grinding millGrinding Mills Metallurgist & Mineral Processing EngineerFor primary grinding, there is a high output of fines achieved even with relatively low energy input, illustrating one of the main advantages of the HPGR 17 Installation of the grinding roll as primary mill increases ball mill output by about 15%, with energy saving close to 510% of total energy requirement based on conventional ball mill grinding systems with a specific energy requirementOPTIONS FOR GRINDING SLAG AND POZZOLAN FOR USE AS
