Abstract

Rührwerkskugelmühle mit einem eine Rührwelle (20) umgebenden Mahlbehälter (12) der mit einem Produkteinlaß (42) und einem Produktauslaß (34) versehen ist, wobei die innerhalb des Mahlbehälters (12) befindlichen Mahlhilfskörper durch die Rotation der Rührwelle aktiviert und von einer Trenn- und/oder Vorklassiereinrichtung im Mahlraum (16) zurückgehalten werden. Zur optimalen Energie- und Raumausnutzung ist dem Mahlraum (16) eine Vorzerkleinerungseinrichtung (50) vorgeschaltet. Die Vorzerkleinerungseinrichtung (50) weist entweder einen statischen oder dynamischen Spaltschutz (68) auf.

Figure imgaf001
Agitator ball mill comprising a grinding container (12) surrounding a stirring shaft (20) and having a product inlet (42) and a product outlet (34), the grinding auxiliary bodies located inside the grinding container (12) being activated by the rotation of the stirring shaft and separated by a separating and / or pre-classifier are retained in the grinding chamber (16). For optimum energy and space utilization, the grinding chamber (16) is preceded by a pre-shredding device (50). The pre-shredding device (50) has either a static or dynamic gap protection (68).
