Device for comminuting feedstock

摘要

A device for comminuting feedstock having a rotor, rotating within a housing around an axis, with rotor tools lying within the outer circumferential region on a circumferential ring and a stator, associated with the rotor, with stator tools arranged concentrically in the outer circumferential region and forming a comminuting surface, whereby the rotor tools and the stator tools lie opposite at a distance with the formation of a working gap and the stator tools are formed by segments, which to form the comminuting surface rest on the stator with their rear side and lie with their long sides against one another. The segments are attached to the stator in each case with their first short side and second short side by a positive fit, whereby the stator has a clamping element, which works together with the first short side and/or second short side to clamp the segments against the stator.

1. A device for comminuting feedstock, the device comprising:
a housing; a rotor configured to rotate within the housing about an axis; rotor tools arranged within an outer circumferential region on a circumferential ring; and a stator associated with the rotor, the stator having stator tools arranged concentrically in the outer circumferential region and forming a comminuting surface, wherein the rotor tools and the stator tools lie opposite to one another at a distance thereby forming a working gap, wherein the stator tools are formed by segments, which to form the comminuting surface rest on the stator with their rear side and lie with their long sides against one another, wherein the segments are attachable to the stator with their first short side and second short side by a positive fit, wherein the stator has a clamping element, which contacts the first short side to clamp the segments against the stator, wherein an extending direction of the first short side and the second short side is parallel to the first short side and the second short side, wherein the extending direction is perpendicular to an axial direction of the axis, wherein the stator includes a circumferential collar portion that protrudes from the stator, wherein the second short side of the segments directly contact the circumferential collar portion, wherein the clamping element is a clamping ring that is detachable from the stator and is concentric with the stator so as to clamp all of the segments, wherein the clamping ring directly contacts both the stator and the first short side of all of the segments, wherein the rotor and stator are formed cylindrical or conical, and wherein the segments have a flat, planar rear side and along the longitudinal edges, formed by the rear side and long sides, rest against the stator.
