Critical speed can also be affected by shaft straightness and assembly alignment, it is recommended the maximum speed be limited to 80% of the calculated value. To Use This Chart. Determine the maximum RPM. Determine the maximum length between bearings. Determine end fixity. Find point at which length and speed intersect.

A ball mill inside the Mayflower Mill near Silverton, Colorado. The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and nonferrous metals.

Critical Speed: Ball Inch Screws TO USE THIS CHART: Determine maximum travel rate required. Determine screw length L. Find point at which travel rate and screw length intersect and select a screw above and to the right of that point.

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 (although this depends upon feed input size mills including a roller press are mostly singlechambered), allowing the use of different sizes of grinding media.
