1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell's inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula. The mill speed is typically defined as the percent of the Theoretical ...

The critical speed must be known in order to calculate the optimum speed, which is the speed that you actually want your jar to rotate at. The 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 ...

The critical speed may be estimated based on the following relationship : Critical speed (rpm) = 54 / R ft where R ft is the diameter of the vessel measured in feet. As the rotational speed of the vessel decreases, attrition plays a more dominant role in particle size reduction relative to impaction and compression, yielding finer particles at ...
