A roller crusher (1) having two generally parallel rollers (2) arranged to rotate in opposite directions, towards each other, and separated by a gap 5 is disclosed. Each roller (2) has a first end (3) and a second end (4). The roller crusher (1) comprises a flange (5) attached to at least one of said ends (3, 4) of one of said rollers (2). The flange (5) extends in a radial direction and has a height (H) above an outer surface (6) of said roller (2) which is sufficient to extend across said gap substantially along a nip 10 angle (a) of said roller crusher (1).
