Get PriceThe optimum speed varies as a percentage of the critical speed depending on the viscosity of the material being ground. For the dry powders used in pyrotechnics, the optimum speed will be 65 of the critical speed. Using the interactive calculator on this page will help you determine the optimal speed for your mill without having to reach
Get PriceThe critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shell. Ball mill machines usually operates at 65-75 of critical speed.
