Abstract

A grinding mill has a housing which includes a feed hopper and a downwardly converging chamber located below the feed hopper and having an upper region and a lower region which is provided with an outlet. A pair of cooperating grinding rollers are arranged in substantially axial parallelism in the upper region of the chamber spaced from the feed hopper and define with one another a grinding gap from which ground material drops into the lower region. A first pneumatic conduit conveys material to be ground from the region of the feed hopper to the region of the grinding gap. A feeding arrangement feeds the ground material from the lower region through the outlet into a second pneumatic conduit, and a suction conduit is provided which has one open end portion communicating with the second pneumatic conduit and another open end portion located proximal to the grinding gap. The suction conduit serves to aspirate air from the first pneumatic conduit into the second pneumatic conduit via the region of the grinding gap, so as to maintain suction in this region and also-via the first pneumatic conduit-in the feed hopper.
