The working principle of ball mill Meetyou Carbide

The ball mill consists of a metal cylinder and a ball The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of frictionRod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods The power needed to operate a rod mill could exceed 30% of the power used in a ball mill When they are worn, rods must not stretch but break in rather small pieces, so that they can exitfor grinding plant purpose rod ball millreliable quality cylindrical ball mill Ball Mill for Sale Grinding Machine JXSC Mining Nov 26, 2019 Ball mill is the key equipment for grinding materials those grinding mills are widely used in the mining process, and it has a wide range of usage in grinding mineral or material into fine powder, such as gold, iron,zinc ore, copper, etc JXSC Mining produce reliable effective ball millreliable quality rod ball mill
