Rpm Optimal Ball Mill
Ball mills are normally operated at around 75 of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers, allowing the use of different sizes of grinding media. An underloaded mill will have sub-optimal milling performance and accelerated media wear.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”.

The ball diameter of 5 mm is optimal at 50 rpm of rotation speed (the resultant average particle size of the milled powder is 23 μm), ball diameter of 3 mm is optimal at 100 rpm (14 μm), and 2 mm is optimal at 153 rpm (084 μm) From this result, it can be said that the optimal ball size for efficient milling decreases with the rotation speed of the mill
