A shredder has a pair of plates with interdigitated teeth that can be relatively rotated for shredding vegetative material. A receptacle mounted in a housing can hold vegetative material shed from a location between the pair of plates. A screen in the receptacle can separate fine material and store it at a relatively low position for later usage. A weighing device mounted at the housing can weigh vegetative material in the receptacle.

A wood chipper, a flywheel therefor, and a process of making the flywheel. A plurality of plates are laser cut to each have a thickness up to about inch, including laser cutting a plurality of apertures in each of the plates and laser cutting a central opening in each of the plates for receiving a shaft for effecting rotation of the flywheel. The plurality of plates are laminated together by inserting fasteners in corresponding ones of the apertures in the plates. At least one knife is attached to the laminated plates for cutting wood material to form chips of the wood material as the flywheel is rotated.

A machine for distributing loosefill insulation material is provided. The machine includes a chute having an inlet end and an outlet end. The inlet end is configured to receive compressed loosefill insulation material. A lower unit has a shredding chamber configured to receive the compressed loosefill insulation material from the outlet end of the chute. The shredding chamber includes a plurality of shredders configured to shred, pick apart and condition the loosefill insulation material. The shredders include a shredder shaft and a plurality of vane assemblies. The vane assemblies are oriented such that adjacent vane assemblies are offset from each other by an angle in a range of from about 45 to about 75. A discharge mechanism is mounted to receive conditioned loosefill insulation material exiting the shredding chamber. The discharge mechanism is configured to distribute the conditioned loosefill insulation material into an airstream. A blower is configured to provide the airstream flowing through the discharge mechanism.

A bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.
