ABSTRACT:
An apparatus for milling particulate mineral material comprises two cylinders rotatable in opposite directions about parallel axes defining a plane while being yieldingly pressed towards each other, the cylinders defining therebetween a milling compression space having an inlet for the particulate material above the plane and an outlet for the milled material below the plane. To reduce the formation of agglomerates and prevent circumferential and/or lateral flushing of the material, the outlet space is closed by respective lateral flanges at the opposite cylinder end faces and a barrier including a scraping bar extending across the outlet space below the plane into contact with the flanges and having one edge in contact with the peripheral surface of one of the cylinders while an opposite edge defines a milled material output of reduced cross sectional area with the peripheral surface of the other cylinder.
