Patent number: 5154363Abstract: A self-contained reciprocating action miller having a grinding mill housed within a mill housing and rotating about a grinding axis. A refuse hopper mounted above the mill housing has a convex floor with an opening therein to expose the grinding mill. Reciprocating feed apparatus mounted within the refuse hopper reciprocates two parallel, spaced-apart vertical walls along an axis parallel to the grinding axis to gradually feed the refuse into the grinding mill at a steady rate to prevent jamming of the mill when grinding tough refuse. Shear plates in the form of segments of a circle are positioned adjacent the rotor for comminuting shreddable or grindable material while guiding noncomminutable materials through the mill. A reversible rotor, stator, and discharge chute allow the comminuted material to be discharged from either side of the mill with no loss of grinding efficiency.Type: GrantFiled: August 31, 1990Date of Patent: October 13, 1992Inventor: William A.

Patent number: 5104047Abstract: Disclosed is a wet process recovery system for solid waste. The waste is fed into a hydrokinetic separation step wherein it is immersed in a body of water which is subjected to rising and lateral flows. These flows establish a synthetic gravitational environment to effect separation of solids above and below a predetermined density greater than the density of water. The solids having the higher densities are collected by gravity and transported from the water for recycling. A modified hammermill is connected to the body of water and the rising and lateral fluid flows cooperate to carry waste into a cutting and ejecting mechanism which both shears friable waste and dynamically ejects non-friable waste back into the liquid. The output of the hammermill is a slurry of comminuted waste in the liquid. This is pumped to a centrifuge separator where solid waste is separated from liquid and the liquid recirculated to the body of water to create the flows in that body.Type: GrantFiled: August 21, 1990Date of Patent: April 14, 1992Inventor: Leonard E. Simmons
