THE OPTIMAL BALL DIAMETER IN A MILL

Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.

Ball Mills

Ball mills are very useful for fine grinding of the materials like limestone, clinker, iron ore and other minerals. Mills of varied capacity 2 kg, 5 kg & 10 kg are available with recommended quantity of grinding media of assorted balls sizes. Provision exists for both wet/dry grinding as a cooling jacket is provided.

Feed Size VS Ball Size

One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 = 6 mm would need a ball size of 75 mm. An empirical model from "Emerging Trends in Mineral Processing", 2005, is ...

Profile milling

If using a nominal diameter value of the tool when calculating the cutting speed of a ball nose or round insert cutter, the true cutting speed, v c, will be much lower, if the depth of cut, a p, is shallow. Table feed and productivity will be severely hampered. Base calculations of cutting speed on true or effective diameter in cut, DCAP.

Ball Mill Feeders

The entire mill feed enters the drum via a chute or spout and an internal spiral carries the feed into the trunnion liner. The drum feeder may be used in lieu of a spout feeder when headroom limits direct spouting. The drum also provides a convenient method of adding grinding balls to a ball mill. The drum is generally lined with Manganese Steel.
