Abstract:
A roller-type reducing apparatus (10) comprising reducing rollers (13, 14) mounted within a housing (1) for rotation in opposite directions, said rollers comprising differently serrated reducing discs (13a, 14a) having different diameters and mounted alternatingly on a common shaft (27, 27a) in such a manner that each greater-diameter reducing disc (14a) of one reducing roller (14) corresponds to a smaller-diameter reducing disc (13a) of another reducing roller (13), wherein the smaller diameter reducing discs (13a) have fine serrations (18) and the greater-diameter reducing discs (14a) have coarse serrations (17) and wherein the reducing discs (13a) with fine serrations (18) have a diameter smaller than the reducing discs (14a) with coarse serrations (17).
