There is provided a refining device in which a first rotor portion has a plurality of first blades radially installed around a rotation shaft, a second rotor portion has a plurality of second blades radially installed around the rotation shaft, in a state where a rotor is rotating, a raw material charged from a charging port is refined when sequentially passing between a liner and an end portion on an outer peripheral side of the first blade and between the liner and an end portion on an outer peripheral side of the second blade, and is discharged from the discharge port, and D1>D2, where a separation distance between the liner and the end portion on the outer peripheral side of the first blade is D1, and a separation distance between the liner and the end portion on the outer peripheral side of the second blade is D2.

A modular shredder and grinder apparatus includes a grinder assembly that has a grinder shaft assembly. The grinder assembly has a grinder opening and a shredder assembly movable with respect to the grinder opening to allow access to the grinder shaft assembly. Scrap material is first fed into the shredder assembly so that shredded scrap material is received through the grinder opening and further cut by the grinder shaft assembly.

Static plant for preparing feed mixes for ruminant livestock, having a conveyor unit for conveying the feed mix ingredients, chain and/or screw feeders, feeders with weight sensors and supplementary conveyor belt, silos of solid ingredients, and silos of liquid ingredients, independently supplying via the conveyor unit, with dual flow, two or more high-capacity mixers.

A foam glass aggregate slicing and reduction machine and system which rapidly, effectively, and economically reduces large pieces of aggregate to required sizes with minimal powdery waste. The machine comprises a foam glass aggregate collection chute having a bottom outlet section for discharging foam glass aggregate onto a holdbar located adjacent to the outlet section. A rotating roller supports a plurality of rotating roller knives which slices large pieces of foam glass aggregate to reduce the aggregate to fragments, with minimal powdery waste. A foam glass aggregate guide member directs foam glass aggregate towards the rotating roller. A foam glass aggregate filtering bar having rows of intervening spaces is located below the guide member and adjacent to the rotating roller.

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 means of 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, in particular at least one side wall arranged on the end face with respect to the axial direction of the shredding shaft, is formed such that it can be moved, in particular folded or displaced, from a use position into a maintenance position.

A 3 in 1 reverse vending machine. A vending machine that is solar powered and accepts bottles and cans made of plastic, aluminum, and glass. The machine includes a conveyor system, barcode reader and cleaning system, this prepares the bottle and cans to be shredded and then granulated into small pieces. The machine houses a delivery system that carries the smaller pieces of processed material to its predetermined receptacle for storage. Each bottle and can has a monetary value once received by the machine that will be issued to the user once all bottles and cans are received and calculated per user per transaction.

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.

Multi jet abrasive head for cleaning/removing material surfaces and splitting/cutting materials by a liquid beam enriched with solid abrasive particles with a uniform velocity and density profile allowing the cutting power to be increased with more efficient cutting beam usage.

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 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.
