Does ball mill only rely on its RPM for grinding ? How about friction inside the jar?

05 May 2016 1 2K Report

ball mill, stainless steel media, friction

Obviously the friction can appear if there is a motion. So, there is a relation between RPM and friction force.

However, for a an optimum grinding the ball size distribution and the numbers, and RPM which in per se determines the falling height of the balls should be taken into account in designing.
