The grinding mechanism has a heat dissipation effect.

Disclosed is a deflection distributor refitting kit for a roller crusher. According to the disclosure the deflection distributor refitting kit comprises a deflection distributing shaft, thrust rods each having first and second ends and mounts for attachment of the deflection distributing shaft at a frame of the roller crusher, wherein a first end of each of said thrust rods is attached to the deflection distributing shaft via a lever, and wherein a second end of each of the thrust rods is arranged to be attached to a movable bearing housing of the roller crusher. Also disclosed is a method for mounting the deflection distributor refitting kit, as well as a roller crusher comprising a deflection distributor.

A roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap, where each roller having two ends. The roller crusher includes a flange attached to at least one of the ends of one of the rollers. The roller crusher further includes at least one mechanical scraper and a remote material removal device configured to output a material removing beam towards a target area. The at least one mechanical scraper and the remote material removal device are arranged consecutive to each other at an end of the roller with a flange for at least partially removing material accumulated on the flange and/or on the outer surface at the end of the roller. A method for operating a roller crusher is also provided.

A roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap, where each roller has two ends. The roller crusher includes a flange attached to at least one of the ends of one of the rollers and a movement blocking arrangement structured and arranged to limit the gap between the rollers to a minimum gap of at least 45 mm. The roller crusher further includes at least one scraper positioned at an end of the roller with a flange. The scraper is positioned such that a minimum roller surface distance between each scraping surface of the at least one scraper and the outer surface of the roller is at least 70% of the minimum gap. A method for arrangement of a roller crusher is also provided.

A roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap, where each roller has two ends. The roller crusher includes a flange attached to at least one of the ends of one of the rollers, where the flange extends in a radial direction of the roller and has a height above an outer surface of the roller. The roller crusher further includes at least two scrapers arranged consecutive to each other at an end of the roller with a flange for at least partially removing material accumulated on the flange and/or on the outer surface at the end of the roller. A method for operating a roller crusher is also provided.

The invention relates to a method for monitoring a high-pressure roller press in the course of comminuting, compacting, or briquetting material. The roller press has two rotationally driven press rollers, between which a rolling gap is formed with a gap width that can be modified during operation. During operation, operational data of the roller press is ascertained by one or more measurement value sensors and is stored on a computer. The method is characterized in that the operational data is stored as raw data on an edge computer, as an analysis computer, which is stationed locally in the region of the roller press and is connected to the measurement value sensors, and the raw data is evaluated on the analysis computer using an analysis algorithm so that characteristic data of the roller press is generated and stored on the analysis computer, wherein the characteristic data is transmitted from the analysis computer to at least one terminal via a wireless network and is displayed on the terminal.
