The maximum safe operating speed of a ballscrew assembly for normal operation is 80% of the critical speed provided the ball speed limit has not been exceed. The critical speed is a function of the unsupported screw length, the screw diameter, and the end bearing supports.

Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement. It has been commonly accepted that the critical rotation speed is a function of a ball radius and a jar diameter.

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
