Abstract
A device for comminuting input material, especially for fine and ultrafine grinding of input material, includes a rotor revolving around a shaft inside a housing, the rotor having a cylindrical or conical jacket surface. An annular gap is present between the housing and the jacket surface, the gap forming a comminution zone and the input material being introduced axially to it. To increase the economic efficiency of the device, it is provided that a plurality of first pin-shaped comminuting tools for comminuting the input material are disposed over the circumference of the rotor, wherein the tools are aligned with their longitudinal direction perpendicular to the jacket surface in the direction of the housing.

A device for comminuting input material for fine and ultrafine grinding of input material, the device comprising:
- a housing;
- a rotor rotating around a shaft inside disposed within the housing, the rotor having a conical jacket surface, wherein an annular gap formed between the housing and the jacket surface forms a comminution zone into which the input material is introduced axially;
- and
- a plurality of first comminuting tools that are pin-shaped for comminuting the input material, the first pin-shaped comminuting tools being disposed on the rotor,
- wherein the first pin-shaped comminuting tools are aligned with their longitudinal direction perpendicular to the jacket surface in the direction of the housing, and
- wherein the rotor includes an end surface perpendicular to the axis of rotation and including an opening in the housing for introducing input material onto the end surface of the rotor such that the input material must move across the end surface before reaching the plurality of first comminuting tools.
