Abstract
A roller crusher having two parallel rollers that rotate in opposite directions and are separated by a gap. At least one of the rollers has a flange at an end thereof. The roller crusher includes a material removal device having a rotatable cutter unit with a plurality of cutter elements arranged tangentially about the rotatable cutter unit at a radial distance from a rotational axis for the rotatable cutter unit. A rotation device rotates the rotatable cutter unit at an end of a roller having a flange. When the cutter unit is rotated by the rotation device, the cutter unit at least partially cuts away material accumulated on the flange and/or on the envelope surface at an end portion of the roller adjacent the flange. Each cutter elements presents an impact surface that faces the material to be cut away and is a polycrystalline diamond (PCD).
