A mincer includes a housing, a hinged door, a handle, a cam, an axle, and a plurality of circular blades mounted on the axle. Rotation of the handle or knob with respect to the housing causes rotation of the cam with respect to the housing, which in turn causes the axle and the blades mounted thereon to travel radially outward or inward with respect to the housing to extend or retract the blades out of or into the housing. The mincer can be operated to extend the blades for operation and to retract the blades for storage. The door can be closed for operation and opened for cleaning of the mincer.

Provided are a shredder assuring greater freedom in designing a feedstock supplier that supplies sheets, and a sheet manufacturing apparatus. The shredder has a feedstock supplier having a supply opening through which a sheet is supplied; and a shredding device configured to shred the sheet supplied from the feedstock supplier. The shredding device includes a rotary cutter that rotates on a first axis, and a circulating cutter that moves in an endless path and cuts the sheet in conjunction with the rotary cutter. The circulating cutter includes a conveyor configured to convey the sheet from the feedstock supplier to the rotary cutter.

An herbal grinding device has a housing. A chute is formed through the housing. A shredding mechanism is positioned within the chute. The shredding mechanism moves an herbal product through the chute while shredding the herbal product. The shredding mechanism is heated to prevent resin from the herbal product from sticking to the shredding mechanism.

An ammunition disposal system having a chute access portion; a collection chamber attached such that a chute access portion interior cavity is in fluid communication with a collection chamber interior cavity; a shredder assembly attached such that the collection chamber interior cavity is in fluid communication with a shredder assembly interior cavity, with one or more shredder blade assemblies positioned within the shredder assembly interior cavity; a hopper attached such that the shredder assembly interior cavity is in fluid communication with a hopper interior cavity; an extractor attached such that the hopper interior cavity is in fluid communication with an extractor interior cavity, and wherein an auger is positioned within at least a portion of the extractor interior cavity; and a liquid contained within at least a portion of the collection chamber interior cavity, the shredder assembly interior cavity, the hopper interior cavity, and the extractor interior cavity.

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.

A reversible grinder pump with cutter plate and cutter blade, wherein the cutter plate is attached to an inlet of the reversible grinder pump and is located adjacent to the cutter blade, wherein the cutter plate includes pairs of angled openings, wherein each of the pair of angled openings extends through the cutter plate and has a shape which is a mirror image of the other angled opening of the pair of angled openings, when viewed from above a surface of the cutter plate. The cutter blade of the reversible grinder pump contains a pair of triangular cross section, prism-shaped cutting edges, which are congruent to each other and reflective, extending in opposite directions from each other.

A plastics recycling preparation container canister includes a stationary disc configured with cutting teeth disposed on an axial surface thereof, the stationary disc disposed substantially orthogonal to an underside of a hinged lid for the container. The container canister also includes a spinning disc configured with cutting teeth disposed on an axial surface thereof, the spinning disc disposed on a sidewall of the container. A ramp for directing plastics to be shredded to the spinning disc is implemented followed by the stationary disc swung into a parallel position to the spinning disc in a sandwich configuration around the plastics to be shredded. The stationary disc and the spinning disc are separated by a space configured to accommodate the respective cutting teeth thereof and a space for shards of the plastic consumer recyclable. The cutting teeth of both discs are shaped like a parrot's beak comprising a rhinotheca tomium cutting surface.
