Chapter 10 Selection of Fine Grinding Mills - ScienceDirect
Figure 3 shows the schematic diagram of one of the axial flow-type impact mills called a Super Micron Mill E. This mill has a larger processing volume and operated at a middle-range speed but is capable of the finer grinding by the attrition mechanism and separation nozzle to discharge foreign materials, which often cause the reduction in the grinding capacity and the product quality.

Gloss Control and the Role of Particle Size | PCI Magazine
Primary crushing reduces the large lumps to around 25 mm in size, and further processing through a roller mill takes this down to 45 - 50 microns. These particles then form the feedstock for a state-of-the-art air-jet mill. The properties of both the feedstock and product from the air-jet mill are monitored using the Mastersizer 2000 system.
