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= [0.4886/ (2 p)] x [9.812/ (1 - 0.025)]0.5

The following equation is used to determine the power that wet grinding overflowball millsshould draw. Formillslarger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by themill. This is called theballsize factor S. Rod andBall Millsby C.A. Rowland and D.M. Kjos @ Allis-Chalmers

The speed of the motor can be found by using Speed measurement devices. Hence motor torque T = P / ω. Here omega ω is equal to 2 x pi x N (rpm) / 60. For DC Motor torque Formula: For Calculating, Torque for DC motor.T = V x I / (2 x pi x N (rpm) / 60) N (rpm)is the speed of the motor. V => Input DC Voltage. I => Input DC Current
