The time has come to re-think the approach to mill drive motors because of the growth in size of newer ball mills, the starting torque restrictions of some of the newer mill drive configurations, and the softness of some utility services. This paper looks at the serviceability and economics of five different mill motor options to meet these restraints. Some approaches are …

The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.

In general, plunge milling is an alternate method when side milling is not possible due to vibrations. For example: When the tool overhang is greater than 4 x DC. When the stability is poor. For semi-finishing corners. For difficult-to-cut material, such as titanium. It can also be an alternative when machine power or torque is a limitation.
