Abstract

Es sind eine Rührwerkskugelmühle (10) mit einem insbesondere horizontalen Mahlbehälter (12), der einen ersten Endbereich mit einem Mahlguteinlass (14) und einen zweiten Endbereich mit einem Mahlgutauslass (16) aufweist, und ein Verfahren zum Betreiben einer Rührwerkskugelmühle (10) offenbart. Die Rührwerkskugelmühle (10) umfasst eine im Mahlbehälter (12) bzw. im Mahlraum (18) mittels einer Antriebseinheit rotierbare Welle (20), welche zumindest abschnittsweise als Rührwelle (22) ausgebildet und mit Rührelementen (24) ausgestattet ist, sowie eine Trennvorrichtung (30). Die Trennvorrichtung (30) umfasst einen Klassierrotor (32), welcher auf der Rührwelle (22) axial beabstandet zum Mahlgutauslass (16) angeordnet ist und einen rotierbaren Rotorkäfig (34) besitzt, sowie eine innerhalb des Rotorkäfigs (34) angeordnete und am Klassierrotor (32) befestigte Siebeinheit (42).An agitator ball mill (10) with a particularly horizontal grinding container (12), which has a first end area with a grinding material inlet (14) and a second end area with a grinding material outlet (16), and a method for operating an agitating ball mill (10) are disclosed. The agitator ball mill (10) comprises a shaft (20) which can be rotated in the grinding container (12) or in the grinding chamber (18) by means of a drive unit, which is designed at least in sections as a stirring shaft (22) and equipped with stirring elements (24), as well as a separating device ( 30). The separating device (30) comprises a classifying rotor (32) which is arranged on the agitator shaft (22) axially at a distance from the grinding stock outlet (16) and has a rotatable rotor cage (34), as well as a rotor cage (34) arranged inside the rotor cage (34) and on the classifying rotor ( 32) attached sieve unit (42).
