An organic material and plant vine chopper assembly has two plant vine chopper rotor drum assemblies that chop plant vines and other organic material. Each rotor drum assembly has a plurality of rotor rings each ring having a plurality of angled blades that effectively cooperate with each other to guard each blade and the drum against the wrapping of clogging fibrous strands and other clogging material around the drum. Each chopper rotor drum assembly incorporates a plurality of rotor rings spaced along and encircling and attached to a main drum tube and distributed in a cutting zone along and surrounding the longitudinal rotational axis of the drum tube with each rotor ring having a pair or a plurality of pairs of cutting blades attached to respective alternately angled mounting tabs that alternate to the left and to the right to the general plane of the rotor ring.

An apparatus for converting cellulose into nanocellulose. The apparatus includes a tank, a motor, and spherical member. The tank has a tank floor. The motor is supported adjacent to the tank. The motor has a motor shaft. The motor shaft has a first end driven by the motor and a second end. The spherical member is connected to the second end of the motor shaft to rotate the spherical member when the motor is energized. The cellulose material is introduced into the tank and drawn between the spherical member and the tank floor to compress the cellulose material in controlled liquid environment.

A bone grinder is provided herein. The 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.

Detonable devices such as charged air bag inflators are fed to a shred tower at a controlled feed rate via a feed valve. Water spray and/or water baths in the shred tower prevent sparking and begin to solubilize chemicals while the inflators are fed to primary and optional secondary shredders respectively performing course and fine shreds. A sump receives the shredded material which continues to solubilize and separate chemicals from metal. A conveyor lifts solids from the sump. Dewatered solids are fed to a receiving box for metal scrap recycling.

A shaft shredder having a machine frame and a shredding unit. The shredding unit has at least one shredding shaft that is mounted therein and is driven by a drive. A material feeding region is formed adjacently to the shredding unit and has a plurality of side walls. At least one of the side walls that is arranged on the end face with respect to the axial direction of the shredding shaft is formed such that it can be moved from a use position into a maintenance position.

A shredder system and methods for shredding recyclable material including a primary shredder that shreds recyclable material into a first larger shred size and a secondary shredder that shreds recyclable material into a second smaller shred size material. The secondary shredder includes a rotor and a knife that meshes with the rotor to cause all of the first larger shred size material to be further shredded to the second smaller shred size material. The secondary shredder may also include a diverter mechanism capable of diverting the first larger shred size material. Either the diverter mechanism or the knife can move relative to the rotor to create an opening that allows the first larger shred size material to avoid being further shredded into the second smaller shred size material. The shredder system may be disposed in a motor vehicle.

Processing of baled material includes a bale opening stage, a separation stage, and a decortication stage. The bale opener features a conveyor moving incoming bales toward a toothed extractor with an array of teeth driven on a revolutionary path moving upwardly past the adjacent end of the conveyor to rake through the bale and extract material therefrom. The conveyor tilts upward reduce a working angle between the conveyor and the toothed extractor to urge the shrinking bale toward the moving teeth. A separation stage features multiple sets of vertically stacked, counter-rotating rollers with different characteristics from one set to the next. A decorticator has an external container, an internal drum rotatably supported therein, and an array of teeth on the drum. Driven rotation of the internal drum spins the fibrous stalks around the internal drum and impacts the fibrous stalks against surrounding interior wall surfaces of the external container.

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.

There is provided a scrap crushing and carrying apparatus, including: a coarse crusher for crushing scraps; a fine crusher for further crushing the scraps crushed by the coarse crusher; and a carrier for storing the scraps or carrying the scraps to the coarse crusher or the fine crusher. The carrier includes a filter unit provided inside the carrier to collect dust in the carrier.

A granulator includes a rotary crushing blade for crushing an object to be processed that has been fed into a main body. A stationary granulating blade includes a plurality of small shearing blades below the rotary crushing blade. A movable granulating blade includes a plurality of shearing blades below the rotary crushing blade. The granulator includes an oscillating shaft pivotably supporting the movable granulating blade so as to be oscillatable in directions in which the movable granulating blade moves toward or away from the stationary granulating blade. A driving mechanism is provided for oscillating the oscillating shaft, in which the movable granulating blade is detachably fixed to a movable blade holder and the movable blade holder is detachably fixed to the oscillating shaft.
