Apparatus for and method of comminuting agglomerates

Apparatus for comminuting agglomerates material to be comminuted, comprising a rotor (1) which is drivable in rotation and which has a plurality of blade-like comminuting tools (24) which can be brought into contact with the material in order to comminute same, characterised in that the comminuting tools comprise narrow knives (24) whose thickness measured in the axial direction of the rotor does not exceed 20 mm and whose repetition spacing in the axial direction is a maximum of 50 mm, characterized in that the rotor is axially movably mounted, wherein there are provided devices for axial reciprocating movement of the rotor during the rotation of the rotor about its axis.

A method of comminuting agglomerates material which is comminutable by mechanical blows, wherein an apparatus is employed having a rotor for contacting the material and which rotor carries blade-like comminuting tools used for comminuting the material by mechanical blows, characterised by the steps of using the rotor to contact the material, and comminuting the material with knives which are of a thickness of at least 3 mm and at most 7 mm measured in the axial direction of the rotor and an axial repetition spacing of less than 30 mm, the overall rotor diameter being from between 150 and 400 mm, and the length of the individual knives being at least 25% of the overall rotor diameter.
