The "pulverisette 4" vario-planetary mill is capable of emulating ball mills of conventional design, simulating the types of stress entailed and thus reproduc-ing or optimising grinding processes. Due to the high flexibility available for se-lecting the grinding parameters, it is possible to achieve results unattainable with any other ball mills.

The principle of mill operation is the impingement of the solids between pieces of media. The majority of media motion and milling occurs on the surface of the bed of media where the media is cascading. If there are too few solids, then media will strike media with little milling effect but with accelerated wear of the media and mill shell.

Virtually all modern raw mills incorporate closed circuits with classifi- cation in a cyclone or mechanical separator and return of coarse mater- ial for regrinding (Figure 3). Ball mill operation is described in more detail under finish milling (Section 5.2). Roller mills have a lower specific power consumption than ball mills.

CAUTION! Because the tool spins on a mill, hot chips can be thrown much farther than when using a lathe. Safety glasses and proper clothing are a must for all milling operations. Milling on a vertical mill is usually accomplished with end mills. These cutters are designed to cut with both their side and end. (See Figure 12.)
