Grinding mills are size reductions machines that often follow crushers in the processes where finer products are desired after crushing. Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. Because of the name, verb milling is also been used as a synonym for grinding.

Use a smaller nose radius and/or a sharper cutting edge. Reduce the cutting depth and increase the feed. Change the cutting speed. Use a better tool clamping system (, SecoCapto and Seco Steadyline tooling). Apply the first advice use a cuttingedge angle close to 90° differently in a milling application.

This is the reference exact grinding status of the mill when the output particle size is of 75 microns. If the cross correlation coefficient decreases below, it means that the grinding in the mill is not happening properly and the mill should be checked to control its feed rate, pulp density, liner and lifter conditions etc. (a) (b) Fig. 8.

Safety measures for grinding machines are, in particular, characterized by guards with interlocking and guard locking, to effectively counteract risks of fracture of ceramic tools. In some special cases of grinding operations, guards can be regarded as disturbing by the operator because they obstruct process monitoring.

As a result, vibration is minimized and cutting conditions optimized. It is quite feasible to machine components that require a tool overhang of more than 10 times the tool diameter. Furthermore, with cemented carbide reinforced special bars, overhangs of 14 times the tool diameter can be dealt with successfully.
