Abstract
A high-pressure roller press has a press frame, fixed and movable compression rollers rotatable about respective roller axes in the press frame, each having axially opposite roller ends in turn having end faces, and together forming a compaction zone with a roller gap vertically level with the roller axes and having a gap width that is variable during operation of the roller press. Two end plates axially flank the compaction zone at the roller ends, are mounted on the press frame so as to be movable, and are prestressed to shift axially outward away from the respective roller end faces against a prestress force during operation of the roller press. Respective single end rollers rotatable about respective end-roller axes axially delimit the roller gap and are mounted on the end plates vertically level with the roller gap.
