Abstract
An air-swept mill has an annular space with a blade ring between a rotary grinding pan and a casing wall for fluid delivery flow. The annular space and the blade ring form a gas directing or guiding device for rotary flow and circulation flow of the fluid delivery flow. Above the grinding pan, in the vicinity of a classifier, the casing wall is provided with at least one removal device for removing a part of an outer oversize flow, which is formed as a vented concentrated flow substantially directly at the casing wall.
