The cheek plate (1) is provided at the front or rear of a pair of press rolls (32a, 32b) which are disposed laterally. Furthermore, a liquid drain port (14) is provided in such a way as to face a raw material catching section (33) for the press rolls (32a, 32b). The inlet side of the liquid drain port (14) is provided with a wedge wire screen (2) in such a way that liquid passage slots (22) thereof are disposed vertically or laterally.

Abstract: The invention relates to a material bed roller mill having two rollers (1, 2) which are rotatably supported in a machine frame (3) and driven in opposite directions and whose roller gap, which is charged from above with the grinding material to be comminuted, is delimited at its ends during the operation of the roller mill by a grinding material guide plate (5) which can be removed from its operating position, wherein a) the grinding material guide plate (5) is displaceable in an upward direction and away from the end of the roller gap to such an extent relative to its operating position that the rollers (1, 2) can be removed from the machine frame (3) in the horizontal direction; b) during that displacement movement, the grinding material guide plate (5) is guided by guide bodies along an arc-shaped guide and c) in the operating position, the grinding material guide plate (5) is supported towards the outside against the forces exerted by the grinding material by support members which are connected pivotably

Abstract: A roll mill, particularly a flaking mill with a product channel on each of the axial ends of the rollers utilizes at least two rollers having guide channels with adjoining guide surfaces, at their axial ends, with the guide channels and guide surfaces, conveying the product to be milled into the converging gap or nip of the rollers. The guide surfaces are pivotable via a piston-cylinder unit from an operating position into a discharge position where in the latter position, foreign objects which have accumulated on the guide surface are removed via an open flap, below the guide surface, into a container.

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.

Each wear part is formed by a plurality of small sintered metal plates of small area which are set close against one another like a mosaic and are individually screwed onto the carrier plate so that in case of wear only those small sintered metal plates which are actually worn can be replaced simply, quickly and economically.

Abstract: A roll mill, particularly a flaking mill, for milling particulate material comprises at least two rollers, especially a stationary roller and a movable one, pressed against each other by means of a pressure exerting device. Product is supplied in a width greater than the axial width of the rollers and their nip. Channels are arranged on both lateral ends of the rollers and collect the material fed in excess of the axial length of the rollers, said channels being preferably open towards the rollers, especially over their whole length. Each of said channels discharges onto a guide surface situated above the nip of the rollers and discharges in turn all the material from the channels into the nip above the upper gripping zone of the nip.

Abstract: Helix apparatus fastened to the end flanges on a rotatable beater in a granulator for reducing the size of particles is provided to direct the granular particles from the opposing ends of the beater inwardly toward the central portion to reduce the amount of particles escaping through the opposing end walls of the granulator.

Abstract: A roll mill has sealing devices pressed against the ends of the rolls to seal the roll gap so that material being processed is not squeezed out (such as oil seed during treatment for flaking). The sealing devices include flow guides (such as recesses therein). A curtain of material, wider than the rolls are long, falls onto the roll gap, and so much of it as exceeds the width of the rolls is guided by the flow guides into the roll gap from beyond the ends of the rolls outwardly of the roll ends. This happens because the flow guides themselves extend near the roll gap but stop short of the roll ends. The sealing devices may include a sealing pin surmounted by an elongate wedge member, the two having communicating recesses which together form the flow guide.
