Coal Mill - an overview | ScienceDirect Topics
In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system. The situation is further complicated by the 'mill reject' streams that reject undesirable material (tramp metal and non-coal bearing rock) from the mill.

Introduction to Milling Tools and Their Application
Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but the narrower the channel for chip evacuation.
