Critical speed formula for ball mill.the formula to calculate critical speed is given below n c 42305 sqtdd 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 5090 of the critical speed the factor being influenced by economic consideration.more details. Oct 15, 2015 The mill was rotated at 63% of the critical speed. The position of the balls at the end of five revolutions is shown in Figure 2. It is seen that, using a low coefficient of friction at the walls, balls tend to flow down the surface of the charge, and a toe begins to form. As the friction at the wall increases, cataracting motion is observed.
