Abstract (en)
[origin: WO2021164919A1] The invention relates to a high-pressure roller press (1), in particular a material bed roller mill or a compacting machine, comprising two press rollers (3, 4) which are rotatably mounted in a press frame (2) and are driven in opposite directions and between which a pressure zone (5) is formed with a rolling gap (S) arranged at the height of the roller axis (X, X'), the gap width (W) of said rolling gap being variable during the operation of the roller press (1), wherein the pressure zone (5) between the press rollers (3, 4) is delimited at the roller end faces by delimiting plates (8) arranged laterally next to the press rollers (3, 4), and the delimiting plates (8) are secured to the press frame (2) in a movable manner and under the application of a force such that the delimiting plates (8) can be pushed back against the applied force during the operation of the roller press (1). The invention is characterized in that an individual roller (10) is secured to each delimiting plate (8) at the height of the rolling gap (S), said roller being rotatably mounted about the roller axis (Y) of the roller and laterally delimiting the rolling gap (S).
