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. |
