Abstract (en)

[origin: US2002079391A1] In order to further develop a circuit grinding apparatus with a roller mill or roller press for material bed disintegration of granular material and with at least one integrated sifter, where the mill and the sifter are disposed within two stationary side walls between which a material conveyor ring is rotatably seated and can be set into rotation for an internal circulation of material in such a way that the rotatably seated material conveyor ring, which has a very large diameter and rotates in operation, is as light as possible and the rotary actuator is configured as simply as possible, it is proposed in accordance with the invention to dispose around the bottom circumferential area of the material conveyor ring more than two, for example four rolls supporting the ring on the bottom, where two adjacent bearing rolls in circumferential direction of the ring are positioned at the ends of at least one common rocker lever which, in turn, is supported on the machine frame via a tilting joint.
