Patent ID: 6938845

Claim:
A comminutor apparatus, comprising: a housing having a channel adapted to receive a liquid containing waste products, said channel having an upstream end and a downstream end relative to liquid flow through said channel; a first shaft rotatably mounted within said channel between said upstream end and said downstream end in a substantially upright position normal to said channel; a first set of cutter disks having a first diameter, said first set of cutter disks being mounted on said first shaft for conjoint rotation therewith; a second shaft rotatably mounted within said channel between said upstream end and said downstream end in a substantially upright position normal to said channel; a second set of cutter disks having a second diameter, which is greater than said first diameter of said first set of cutter disks, said second set of cutter disks being mounted on said second shaft for conjoint rotation therewith, said cutter disks of said second set of cutter disks being interleaved with said cutter disks of said first set of cutter disks such that said cutter disks of said second set of cutter disks are positioned proximate to said first shaft and such that said cutter disks of said first set of cutter disks are positioned remote from said second shaft, whereby relatively large, open areas are created between said first set of cutter disks and said second shaft so as to promote flow of liquid through said channel from said upstream end toward said downstream end; and rotating means for rotating said first shaft and said second shaft.
