Abstract
A solid waste pulper including a pulping chamber, oriented at an angle, hng a first inlet port for introducing solid waste material to be pulped, and a second inlet port in the pulping chamber for introducing water into the chamber. A blade assembly, preferably formed of a plurality of rotatable blades and a plurality of fixed blades, is mounted in the chamber for pulping the solid waste material introduced in the chamber, the water mixing with the pulped waste material to form a slurry. A sizing ring is provided in the pulping chamber through which the slurry must pass to be discharged, the sizing ring having a predetermined area for limiting the size of the pulped waste material in the slurry which can be discharged from the pulping chamber. The pulper also includes a discharge port coupled to the pulping chamber for discharging the slurry containing the pulped waste material, the discharge port having a predetermined cross-sectional area which is smaller than the area of the sizing ring, thus limiting the maximum flow of slurry discharged from the pulping chamber.
