ATTRITOR GRINDING MILLS AND NEW DEVELOPMENTS
which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200).
A BASIC UNDERSTANDING OF THE MECHANICS OF
means that necks should not experience plastic deformation or fatigue. However, loads in a mill are not clearly and precisely defined. Of course, there are rules to calculate the maximum stress in rolls caused by design limits for maximum separation force, torque, Hertzian pressure etc, but these criteria are valid

This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains The critical speed must be known in order to calculate the optimum speed, which is the speed that you actually want your jar to rotate at.
Milling Speed and Feed Calculator
Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
