Abstract

The invention relates to a roller crusher (1) having two generally parallel rollers (2) arranged to rotate in opposite directions, towards each other, and separated by a gap, each roller (2) having 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) extending in a radial direction of said roller (2), 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 angle (α) of said roller crusher (1).
