• ### Variables in Ball Mill Operation Paul O. Abbe®

The starting point for mill speed calculations is the critical speed. Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder. Obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the CS. Ball milling is one of the

• ### Milling Step-over Distance Calculator

Milling Step-over Distance Calculator In many milling operations the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result a small cusp of material called a scallop will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight.
