Addition of pebbles to a ball-mill to improve grinding

2017-4-1  The withdrawal of pebbles from the primary milling circuit will cause the feed rate to a primary mill to increase. If one considers both milling stages, the comparison with ball-milling was based on the same final rate of production from the ball-mill(s). Hence, the required rate of production by the primary mill will be reduced (by about 7%).

Addition of pebbles to a ball-mill to improve grinding

2021-5-30  Ball-mills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (7-25 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.
