  • Patent number: 8833687
    Abstract: A grinding assembly for the comminution of material that enhances the durability of the side edges of both a grinding roll and a flange roll. Both the grinding roll and the flange roll include a wear ring that is received within a side groove formed at each end of a cylindrical roll body. The wear ring includes a series of spaced receiving cavities that each receive a wear member. Each wear member includes a radially outer surface and an axial end face to enhance the durability of the edge of the roll body. The edge ring is retained on the roll body by a series of connectors that pass through the edge ring. In the flange roll design, a flange ring is attached to the roll body by a series of connectors that also secure the edge ring to the roll body.

  • Patent number: 5054701
    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.

    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.

  • Patent number: 4193555
    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.
