Abstract
A scraper device for a roller crusher including a rotatable multi head scraper unit having at least two scrapers arranged tangentially about the multi head scraper unit at a radial distance from a rotational axis. The scraper device further includes a rotation actuator to rotate the multi head scraper unit to allow use of one of scrapers at a time. The scraper device further includes at least one brake arrangement to prevent and/or restrict rotation of the multi head scraper unit during operation of the one of the scrapers. Each of the scrapers includes a scraping element having a scraping surface formed from a polycrystalline diamond (PCD). Each scraping surface at least partly faces in a tangential direction defined at the scraper surface and directed along a reference rotational direction of the rotatable multi head scraper unit. A roller crusher including the scraper device and a method for operating the roller crusher is also provided.
