Ball Mill an overview ScienceDirect Topics

The critical speed n rpm when the balls are attached to the wall due to centrifugation: Figure 2.7. Displacement of balls in mill. n = 42.3 D m. where D m is the mill diameter in meters. The optimum rotational speed is usually set at 6580 of the critical speed. These data are approximate and may not be valid for metal particles that tend to agglomerate by welding. The minimal magnitude

Ball Mill Operating Speed Mechanical Operations Solved

The critical speed of ball mill is given by, where R = radius of ball mill r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 of critical speed. If 100 mm dia balls are replaced by 50 mm dia balls, and the other conditions are remaining the same, Speed of ball mill = 0
