High-pressure roller press

A high-pressure roller press comprising:

• a press frame;
• 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 flanking and delimiting the filling funnel between axially outwardly directed end faces of the main rollers, the end plates being mounted on the press frame so as to be axially movable;
• respective end rollers movable axially inward toward the end plates, each end roller being laterally adjacent the main rollers vertically level with the roller gap width, rotatably mounted about its end-roller axis, and laterally delimiting the roller gap width, the end rollers being movable relative to the respective end plates;
• and
• means for urging each of the end plates by biasing forces axially toward of the respective main-roller end faces, the end rollers being pressed axially outward against the biasing forces during operation of the roller press.
