balls which exist in mill, ????: each ball abrasion (g), ??t: total ball abrasion in the mill (g), ??b: each ball volume (m3), ??b: supposed ball filling percentage, A r: ball abrasion rate in the mill. If above calculation were done again for ??b = 2%, total ball abrasion will get 60.96, finally.

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. Get Price.
