Abstract

Um eine Schneidmühle zur Zerkleinerung von Kunststoffen, insbesondere für die Zerkleinerung von Angüssen, mit einem mit Schneidmessern versehenen Schneidrotor (11), der innerhalb eines ebenfalls mit Messern besetzten Gehäuses umläuft, wobei die Drehachse (13) des Schneidrotors gegenüber einer Vertikalen schräggeneigt in einem Gehäuse angeordnet ist und die eine Guteinlaßöffnung (16) sowie einen Gutaustritt (17) aufweist, zu schaffen, bei der der Feinstaubanteil verringert und bei der entstehende Feinstaubreste ohne zusätzliche Vorrichtungen entfernt wird, ist gemäß der Erfindung an der der Gehäuseinnenseite (18) zugewandten Seitenfläche (19) des Schneidrotors (11) eine Scheibe (20) befestigt, deren Durchmesser in etwa dem Schneidkreisdurchmesser des Schneidrotors (11) entspricht.

Figure 00000001
Around a cutting mill for comminuting plastics, in particular for comminuting sprues, with a cutting rotor (11) provided with cutting knives, which rotates within a housing also equipped with knives, the axis of rotation (13) of the cutting rotor being inclined to a vertical in a housing is arranged and which has a material inlet opening (16) and a material outlet (17), in which the fine dust content is reduced and in which the resulting fine dust residue is removed without additional devices, is according to the invention on the side surface facing the inside of the housing (18) ( 19) of the cutting rotor (11) fastens a disc (20) whose diameter corresponds approximately to the cutting circle diameter of the cutting rotor (11).
