A material reducing apparatus includes a reducing head that includes a rotary reducing component that carries a plurality of cutters. The reducing head includes a thrown object deflector positioned proximate the rotary reducing component. The thrown object deflector is configured to limit at least one of a distance and a direction that objects can be thrown by the rotary reducing component.

The invention relates to a method for handling of containers (9) and a handling machine for containers, comprising an inlet arrangement (8), an infeed arrangement (2), a compressing arrangement (20, 21), a cutting arrangement (4, 6) and an outlet arrangement (7), wherein empty containers are compacted. In one embodiment containers are also handled to at least partly be provided in shredded form in the outlet arrangement (7), wherein said cutting arrangement (4, 6) comprises a first cutting unit (4) arranged to cut a container (9) into a plurality of longitudinal, parallel stripes and preferably a second cutting unit (6) arranged to cut transversally in relation to said first cutting unit (4), whereby said longish strips will be cut into a plurality of shredded pieces.

Provided is a hair cutting assembly. The hair cutting assembly includes at least one first shearing wheel, first transmission shaft that drives the first shearing wheel to rotate, at least one second shearing wheel and second transmission shaft that drives the second shearing wheel to rotate. Opposite end surfaces of each first shearing wheel and the corresponding second shearing wheel are attached to each other. The first cutting blades, formed by intersecting end surface of the first shearing wheel with side wall, and the second cutting blades, formed by intersecting end surface of the second shearing wheel with side wall, oppositely move in a feed direction, such that long and thin linear sundries such as hairs and fabrics can be continuously shorn. A floor drain with the hair cutting assembly is also provided.

Featured are a two-stage grinder, an apparatus embodying same and methods related thereto. Such a medical waste grinder includes a first stage and a second stage. The first stage includes spring loaded cutter stacks mounted on two adjacent shafts between two edge plates, each of the cutter stacks including cutters arranged in a helix to create space, each cutter including a number of teeth per blade and including a major diameter and a minor diameter, each cutter turning opposite a fixed counter knife enabling a pinching action against the teeth of the cutter. The second stage includes spring loaded cutter stacks.
