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.

Roller crusher and method for operating thereof

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.
