Abstract

Bei einer Vorrichtung zum Zerkleinern von Schüttgut, insbesondere Fließbett-Gegenstrahlmühle, mit einem mit vertikaler Achse angeordneten Gehäuse (1) das einen unteren, mit mit Druckluft beaufschlagbaren Mahldüsen (5) versehenen Mahlbereich (2) und einen oberen, durch einen vorzugsweise mit einer Schüttgutzuführeinrichtung (6) versehenen Steigbereich (4) vom Mahlbereich (2) distanzierten, mit einer Separiereinrichtung (8) versehenen Separationsbereich (3) aufweist, lassen sich dadurch eine hohe Durchsatzleistung und damit eine gute Wirtschaftlichkeit erreichen, dass der Steigbereich (4) einen gegenüber dem im Bereich der Mahldüsen (5) vorgesehenen, lichten Querschnitt des Mahlbereichs (2) kleineren, lichten Eingangsquerschnitt (13) aufweist.

Figure 00000001
In a device for comminuting bulk material, in particular a fluidized bed counter-jet mill, with a housing (1) arranged with a vertical axis, the lower grinding area (2) provided with compressed air nozzles (5) and an upper one, preferably with a bulk material feed device (6) provided ascending area (4) from the grinding area (2), separated with a separating device (8) provided separation area (3), a high throughput and thus a good economy can be achieved that the ascending area (4) one over the in the area of the grinding nozzles (5) provided, clear cross section of the grinding area (2) has a smaller, clear input cross section (13).
