Abstract

Die Erfindung betrifft eine Mühle 1 zur Zerkleinerung von Mahlgut, insbesondere von Holzhackschnitzeln, mit einem Mahlwerk, das einen Rotor 3 mit einer Vielzahl von Mahlelementen 5 aufweist, wobei der Rotor 3 um eine Rotationsachse R in einem Mahlraum antreibbar ist. Die Innenwand 2 des Mahlraums wirkt mit den Mahleelementen 5 zusammen, um das Mahlgut zu zerkleinern, wobei der Mahlraum eine Zuführöffnung 11 und eine Abführöffnung 13 aufweist, die eine bezüglich der Rotationsachse R im Wesentlichen radiale Zuführung und Abführung von Mahlgut ermöglichen. Die Zuführöffnung 11 und die Abführöffnung 13 sind jeweils im unteren Bereich des Mahlraums angeordnet, wobei die Zuführöffnung 11, der höchste Punkt des Mahlraums, und die Abführöffnung 13 am Umfang der Innenwand 2 des Mahlraums in Rotationsrichtung R des Rotors 3 sequentiell angeordnet sind, und wobei die Abführöffnung 13 siebfrei ist. Die Erfindung betrifft weiterhin ein Verfahren zur Zerkleinerung von Mahlgut in einer Mühle 1.

The invention relates to a mill 1 for comminution of ground material, in particular wood chips, with a grinder having a rotor 3 with a plurality of grinding elements 5, wherein the rotor 3 is driven about a rotation axis R in a grinding chamber. The inner wall 2 of the grinding chamber cooperates with the grinding elements 5 to comminute the material to be ground, wherein the grinding chamber has a feed opening 11 and a discharge opening 13, which allow a substantially radial feed and removal of ground material with respect to the rotation axis R. The feed opening 11 and the discharge opening 13 are respectively arranged in the lower region of the grinding chamber, wherein the feed opening 11, the highest point of the grinding chamber, and the discharge opening 13 are arranged sequentially on the circumference of the inner wall 2 of the grinding chamber in the direction of rotation R of the rotor 3, and wherein the discharge opening 13 is screen-free. The invention further relates to a method for comminuting regrind in a mill 1.
