摘要： The invention relates to a roller crusher having two generally parallel rollers arranged to rotate in opposite directions, towards each other, and separated by a gap, each roller having a first end and a second end. The roller crusher comprises a flange attached to at least one of said ends of one of said rollers. The flange extending in a radial direction of said roller, and has a height above an outer surface of said roller which is sufficient to extend across said gap substantially along a nip angle of said roller crusher.
