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.

Example: a mill measuring 11’0” diameter inside of new shell liners operates at 17.3 rpm. Critical speed is. C.S. = 76.63 / 11^0.5 = 23.1 rpm. Ball and SAG Mills are driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of speed being influenced by economical considerations.

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”.

Ball Nose End Mills. Ball nose mills have a radius at the bottom which makes for a nicer surface finish in your workpiece, meaning less work for you as the piece won’t need to be finished any further. They are used for contour milling, shallow slotting, pocketing and contouring applications.
