ball mill working principle. to be chosen according to the grinding material, material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body, when the ball mill cylinder rotation time, grinding body due to inertia and centrifugal force, the effects of friction, making it attached to the cylinder liner on the cylinder body away, when taken to the height of a
ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel. the ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
220.127.116.11 ball mills. the ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 11.5 times the shell diameter ( figure 8.11). the feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
