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.
Claims17
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.
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 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 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 roller end faces against a prestress force during operation of the roller press, the end plates each having an inner face confronting the respective end face and forming therewith a respective particle-guide pocket set back with respect to the inner face of the respective end plate above the respective end roller fastened thereto so that the respective end roller can be engaged from above by material via the particle-guide pocket;
- respective single end rollers rotatable about respective end-roller axes to axially delimit the roller gap and mounted on the end plates vertically level with the roller gap;
- and
- respective seal plates on the end plates extending parallel to the respective inner faces and partially covering the particle-guide pocket on the front face.
