Abstract:
An apparatus for comminuting solid waste material, comprising:a frame having an enclosure with an entrance for receiving solid waste material, an entrance manifold, and a recycle manifold; and a pair of substantially horizontal, overlapping scissor rolls each having knives along an outer surface and supported for counter-rotation within the enclosure, the rolls driven so the knives on the pair of rolls converge at a lower nip between the rolls, diverge at an upper nip between the rolls, move downward along an outer edge of each roll, and move upward along an intermeshing adjacent edge between the pair of rolls; wherein one roll is a feed roll elevated relative to another roll communicating with the entrance manifold along an outer edge and configured to feed material from the entrance manifold downward along an outer surface of the feed roll, beneath the feed roll and up into the lower nip for severing between the rolls; and wherein the another roll is a recycle roll communicating with the recycle manifold along an outer edge and configured to recycle material from the recycle manifold downward along an outer surface of the recycle roll, and beneath the recycle roll for further delivery up into the lower nip for further severing between the rolls or for collection beneath the rolls.
