  • Publication number: 20230311165
    Abstract: Subject-matter of the invention is a screen plate for a separating device for classifying bulk material. The screen plate comprises a profile region having a profile having depressions and elevations extending in a direction of a takeoff side, the profile being describable by a circle arc of a first circle K1 and a circle arc of a second circle K2, and the circles K1 and K2 being disposed adjacent to one another, with the circle arc of the first circle K1 with a radius r1 describing elevations and the circle arc of the second circle K2 with a radius r2 describing the depressions. Each depression undergoes transition, in a takeoff region, into an opening which expands in the direction of the takeoff side, the opening having an opening edge with a width corresponding to the length of the radius r2 to 2*r2.

  • Patent number: 5723522
    Abstract: The present invention relates to a plastic material which is modified with fiber fillers. Particularly thermoplastic material with melting point above 200 degrees Celsius are selected for this plastic material. As fiber fillers particularly cellulose fibers and/or modified cellulose fibers in practical concentrations of approximately 20% are used.
