Abstract: A high-pressure roller press has a press frame and two main rollers rotatable about respective main-roller axes in the press frame, together forming a filling funnel level with the main-roller axes, and having a gap width that is variable during operation of the roller press. Respective end plates axially flank and delimit the filling funnel between axially outwardly directed end faces of the main rollers. Respective end rollers are movable axially inward toward the end plates with each end roller laterally adjacent the main rollers vertically level with the roller gap, rotatably mounted about its end-roller axis, and laterally delimiting the roller gap, the end rollers being movable relative to the respective end plates. The end plates can each be urged by biasing forces axially toward of the respective main-roller end faces, whereas they are axially outward against the biasing forces during operation of the roller press.

Abstract: 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 filling funnel having a pressure zone (5) is formed with a nip (S) arranged at the height of the roller axis (X, X?), the gap width (W) of said nip being variable during the operation of the roller press (1), wherein the filling funnel 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).
