Abstract

Um eine Kreislaufmahleinrichtung mit Walzenmühle bzw. Walzenpresse zur Gutbettzerkleinerung körnigen Gutmateriales und mit wenigstens einem integrierten Sichter, wobei Mühle und Sichter innerhalb zweier feststehender Seitenwände (12, 13) und einem dazwischen liegenden drehbar gelagerten in Drehung versetzbaren Materialförderring (18) für einen internen Gutmaterialkreislauf angeordnet sind, so weiter zu entwickeln, dass der drehbar gelagerte im Durchmesser sehr große und im Betrieb rotierende Materialförderring (18) möglichst leichtgewichtig und der Drehantrieb möglichst einfach gebaut sein können, wird erfindungsgemäß vorgeschlagen, um den unteren Umfangsbereich des Materialförderringes (18) mehr als zwei, z. B. vier den Ring (18) von unten abstützende Rollen (14 bis 17) anzuordnen, wobei zwei in Ring-Umfangsrichtung benachbarte Lagerrollen (14/15) bzw. (16/17) an den Enden wenigstens eines gemeinsamen Wippenhebels (33, 34) gelagert sind, der seinerseits über ein Kippgelenk (35, 36) am Maschinenrahmen abgestützt ist.

Figure 00000001
Around a circular grinding device with a roller mill or roller press for comminution of granular material and with at least one integrated classifier, the mill and classifier being arranged within two fixed side walls (12, 13) and an intermediate rotatable material conveyor ring (18) which can be rotated and rotated for an internal material circuit are to be further developed so that the rotatably mounted material conveyor ring (18), which is very large in diameter and rotates during operation, can be as light as possible and the rotary drive can be constructed as simply as possible, the invention proposes that the lower peripheral region of the material conveyor ring (18) be more than two , e.g. B. four the ring (18) supporting rollers (14 to 17) from below, two adjacent in the ring circumferential direction bearing rollers (14/15) or (16/17) at the ends of at least one common rocker arm (33, 34th ) are mounted, which in turn is supported on the machine frame via a tilt joint (35, 36).
