Ball Mills - an overview | ScienceDirect Topics
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.

These 498 balls will weigh 0.1827 lb. (0.08 kg.) each and will be 1.06 in. (26.9 mm.) in diameter. At regular intervals all balls less than 1 in. in diameter should be removed from the second-stage mill. If the ball charge in the second-stage mill is screened once a month, there will be 14,940 balls less than 1 in. in diameter to remove.

The optimal L/D ratio range is quite broad again with the minimum in the range of 3.2. For one compartment mills, this optimum should be less due to the lack of the first compartment used for coarse grinding. The optimal ball charge filling ratio for Combi-ball mills is supposed to be less too.
fine dry grinding in ball mills
fine dry grinding in ball mills - ME Mining Machinery. fine dry grinding in ball mills. 1/1/1981 Abstract. The kinetics of dry grinding of several cement clinkers and two coals were investigated in a laboratory tumbling ball mill. The kinetic process is first-order at first, but the rates of breakage decrease as fines accumulate in the bed.
Charge In Dry Grinding Ball Mill
The efficiency of a ball mill depends on the number of contact points between the balls • There is a limit of ball diameter below which centrifuging of mill charge occurs; this limit can only be overcome by a change in the manner of ball movement • In sandmills, the grinding charge is driven by an impeller.
