DEVICE AND GRINDING TOOL FOR COMMINUTING FEED MATERIAL

摘要

A device and a plate-like grinding tool for grinding feed material that has a housing extending along an axis of rotation, in which a rotor rotationally driven about the rotation axis is arranged and includes a plurality of axially parallel grinding tools that are surrounded by a stator with stator tools. The effective edges of the grinding tools are arranged radially spaced from the stator tools by forming a grinding gap extending over an axial length of the grinding gap. The material is fed into the grinding gap on an inlet side and exits from the grinding gap on an outlet side. The axially extending effective edges of the grinding tools are divided in the axial direction into at least two first sections, each with a first radial distance from the rotational axis and into at least one second section with a second radial distance from the axis of rotation.
