  • Publication number: 20090236455
    Abstract: A roller press which is used, in particular, for material bed comminution and into the material feed hopper of which both coarse-grained material, such as, for example, fresh material, and fine-grained material, such as, for example, recirculated grits from a downstream sifter and/or, for example, fly ash, are introduced, wherein the stability of the material bed or grinding bed and therefore a high grinding efficiency are ensured despite the considerably different grain size and grain distribution in the two material flows to be drawn into the roller nip. A pressure screw which conveys the fine material under pressure is inserted into the material feed hopper through at least one fine-grain inlet opening in the hopper, a nozzle-like outlet, in particular a flat nozzle, of the pressure screw extending into a central region of a material draw-in of the press roller nip.
