ABSTRACT:
A sewage cleaning and comminuting system is provided with a pair of dissimilar sized cutter stacks that extends across an influent channel which intercepts all solids too large to pass there through. The dissimilar sized cutter stacks are capable of grinding large and round shaped objects. The cutter stacks rotate at dissimilar speeds and require less energy to grind solids than other grinders having similar sized grinders rotating at the same speed. The system includes an integrated cleaning assembly whereby debris accumulated between the cutter disks is removed as the cutter disks rotate. Embodiments are provided including grinders that employ three and four shafts. Another embodiment is directed to an improved cutter disk. Yet another embodiment includes an auger screen assembly used in conjunction with the comminuting system to remove solids from the effluent stream.
