Correlations for the Grindability of the Ball Mill As a

2.1.2 Critical Speed: If the peripheral speed of the mill is very high, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill and that point is called the Critical Speed” (n c).This phenomenon is called centrifuging. Ball mills usually operate at 65% to 75% of the critical speed.

Ball Mill Capacity and Power Consumption Relationship to

Nov 16, 2020 The acceleration factor of the ball or rod mass is a function of the peripheral speed of the mill. Thus. n = c9np/√D, the above equation becomes P = f1 (D ) f5 (πD c9 np/√D) = cs np D2.5. As a first approximation, the capacity, T, of a mill may be considered as a function of the force acting inside the mill.

† The appendix of the paper lists the mill speed as 12.5 RPM. The mill is fixed speed, so the %critical speed is only a function of mill effective diameter (as liners wear). Doing the math (neglecting the balls) gives a 68.4% critical speed. The ball mill belly length can be achieved with a 18 degree head angle and 1.9 m trunnion diameter.
