Tumbling Mill Critical Speed Mineral Processing & Effect of Speed and Filling on Power. In this section, a 0.545-m x 0.304-m ball mill is simulated to study the combined effect of mill speed and filling on the power draft of the mill. Mill operating speed and filling, among other things, are known to affect the power draft.

The formula to calculate critical speed is given below. N c = 42.305 /sqt(D-d) N c = critical speed of the mill. D = mill diameter specified in meters. d = diameter of the ball. In practice Ball Mills are driven at a speed of 50-90% of the critical speed, the factor being influenced by economic consideration.

Oct 22, 2020· After the tumbling mill working starts, the motor drives the bearing to rotate, and the cylinder rotates at a certain speed. Driven by the tumbling movement, the steel balls, and materials in the cylinder are lifted, thrown off, and ground into powder in the process. Many factors are involved in the tumbling mill working process.
