Abstract (en)

The milling unit with HP roller mills (10,11) is designed so that the both fixed side -end walls (12,13) are assembled together over a housing part (38) housing the rotatable material conveying ring (16), to a housing, tightly enclosing the entire working chamber of the rotary milling unit. In addition the housing part (38) at its underside, has at least one milling material leakage discharge (39 or 40) from the working chamber.

Abstract (de)

Um eine Kreislaufmahleinrichtung mit Walzenmühle (10,11) bzw. Walzenpresse zur Gutbettzerkleinerung körnigen Gutmateriales und mit wenigstens einem integrierten Sichter (21, 22), wobei Mühle und Sichter innerhalb zweier feststehender Seiten-Stirnwände (12, 13) und einem dazwischen liegenden drehbar gelagerten in Drehung versetzbaren Materialförderring (16) für einen internen Gutmaterialkreislauf angeordnet sind, so weiter zu entwickeln, daß Dichtungen zwischen den feststehenden Seiten-Stirnwänden und dem dazwischen liegenden in Drehung versetzbaren Materialförderring (16) nicht mehr notwendig sind, wird erfindungsgemäß vorgeschlagen, die beiden feststehenden Seiten-Stirnwände (12, 13) über ein den drehbaren Materialförderring (16) umhausendes Gehäuseteil (38) insbesondere Ringgehäuseteil zu einem den gesamten Arbeitsraum der Kreislaufmahleinrichtung dicht umschließenden Gehäuse zusammenzufassen, und an der Unterseite des Gehäuseteils (38) wenigstens einen Mahlgutleckage-Austrag (39, 40) aus dem Arbeitsraum der Kreislaufmahleinrichtung anzuordnen. <IMAGE>
