Enter the width of a mill shell liner. Note this is not the width of a lifter You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter above less twice this shell liner width. Mill Actual RPM Enter the measured mill rotation in revolutions per minute.

2004-10-13Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

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.
