1. A high-pressure roller press comprising
a press frame;
compression rollers rotatable about respective roller axes in the press frame, each having axially opposite roller ends each in turn having an end face 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 flanking the compaction zone at the roller ends, the end plates being mounted on the press frame so as to be movable and being prestressed to shift axially outward away from the respective roller end faces against a prestress force during operation of the roller press;
single end rollers rotatable about respective end-roller axes on the end faces to axially delimit the roller gap and mounted on the end plates vertically level with the roller gap, the end plates each having an opening through which the respective end roller passes into or below particle-guide pockets formed between inner faces of the end plates and the end faces of the compression rollers; and
means for feeding a material to be pressed to the particle-guide pockets.
