Abstract

The device for comminution of sticky granular material which tends to agglomerate during conventional milling operations within a grinding mill. It comprises a milling chamber, sieving system and central outlet with a system of grinding rods or plates within the grinding chamber. There is an air feed ring (11) between grinding rotor and sieve rotor, with a rubber membrane (12) fixed to it. The membrane (12) is fixed to the edge of the ring (11) so that it can move to and fro under the influence of the air flow produced during grinding or milling.
