ABSTRACT:
A cutter for a macerator of a type having first and second parallel contra-rotating shafts, each having a plurality of alternate cutters and spacers at the same axial thickness, the cutters of the first shaft being interleaved with those of the second shaft. The cutter of the invention has generally circumferentially spaced teeth 14, 16, 18, 22, each tooth having a front cutting face 26, 28, 30, 32, 34, and an inclined, generally ramp shaped rear face 46, 48, 50, 52, 54, which may be serrated. One tooth 14 has a "square" front face 26 which extends substantially parallel to the axis of the cutter while the front faces of the remaining teeth are inclined, preferably alternately, to the axis of the cutter.
