8.3.2.2 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 1–1.5 times the shell diameter ( figure 8.11). the feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 20–40 water by weight.

Sandreturning ratio is the ratio between the amount of sand return of ball mill and the feeding capacity of raw ore, which can directly affect the productivity of the ball mill. one way to improve the sandreturning ratio is to increase the feeding capacity of raw ore, another way is to reduce the shaft height of the spiral classifier.

The capacity increased with the speed, and when the ore charges were large the greatest efficiency was achieved at about 50 percent of critical. although this speed is the one found to be best in some of the first tests, in which slipping was reduced by using a very short mill, it should be interpreted broadly as indicating a range rather than.

The grid type ball mill discharges the ore by relying on the grid plate, so its production capacity is higher than that of the overflow type ball mill. the overflow ball mill discharges the ore by the gravity flow with the slow speed, so its production capacity is relatively weak, and because the material stays in the ball mill for a long time.

Mill grinding rate over the materials grindability as measured in the lab. mill percent solids optimization has thusly been achieved (mcivor et al., 2000). for media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. ores of different grindability will be part of the discussion.
