Abstract
The invention relates to a method and an apparatus for crushing material of different grain sizes, particularly an air-swept mill. From the method standpoint there is a regulation of the fluid feed flow in the vicinity of a blade ring and with adjustable reinforcing cladding segments, so that grinding material particle flows are moved in a flow envelope, particularly in a hyperboloid torus. From the apparatus standpoint, stationary and adjustable reinforcing cladding segments are arranged as a function of the grinding rollers rolling on a grinding pan. Using adjusting devices, acting on connecting areas of the reinforcing cladding segments, it is possible to bring about a horizontal or radial adjustment and/or an inclination adjustment of the reinforcing cladding segments for regulating the fluid feed flow from the outside and in continuous manner during a crushing process.
