Ball Mills an overview ScienceDirect Topics. The critical speed n (rpm) when the balls remain attached to the wall with the aid of centrifugal force is: n = 42.3 D m. not least because the specific power consumption of vertical mills is about 30% less than that of ball mills and for finely ground cement less still.

SAGMILLING.COM .:. Mill Critical Speed Determination
The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell''s inside surface. This is the rotational speed where balls will not fall away from the mill''s shell. Result #1: This mill would need to spin at RPM to be at 100% critical speed. Result #2: This mill''s

Ball Mills
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.
