Ball Mills Mine Engineercom A ball mill grinds material by rotating a cylinder with steel grinding balls causing the balls to fall back into the cylinder and onto the material to be ground the rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill the larger the diameter the slower the rotation Ball Mills Fritschde Ball millsare the most effective laboratorymillsfor rapid batchwise comminution of mediumhard soft brittle fibrous temperaturesensitive and moist samples down to the finest particle size the comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding
