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 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 having a rhinotheca tomium cutting surface.

Method and apparatus for HDD and electronic waste disposal

A method and apparatus for use in destroying a data storage device and separating materials for recycling. The apparatus employs: a first stage of rough cutting wherein the data storage device is shredded into pieces approximately 30 mm×30 mm; a second stage that separates shredded metal material, such as spindles, from non-metal material by use of a magnetized roller having a scraper to the metal material to a first bin and non-metal material to a third stage having an upper level shredder and a lower level shredder for grinding the non-metal material into particle sizes of 10 mm×10 mm or less.

Hemp Flower Material Stripping Machine and Method
20220250083 · 2022-08-11 ·

A hemp flower, bud, and leaf material stripping machine having a housing, a motor and gearbox that drive a pair of rollers inside the housing, an adjustable locking shaft that adjusts and maintains a space and pressure between the rollers, and a series of feed holes of different diameters on a front side of the housing. Each feed hole is constructed to strip flowers, buds, and leaves from a hemp stem as the stem is inserted into a feed hole and is pulled through the feed hole by the rollers. The flowers, buds, and leaves are severed from the stem at an exterior of the front side of the housing, without damage to the flowers, buds, and leaves. The feed hole is constructed with close tolerance so that the stem can pass through the feed hole but the flowers, buds, and leaves cannot. Hemp stems are stripped in seconds. The flowers, buds, and leaves are not crushed, cut, torn, or compressed as they are severed and fall into a container.

A DEVICE FOR COMPRESSION OF EMPTIED CONTAINERS FOR RECYCLING PURPOSES

A device for compression of emptied containers, the device for compression of emptied containers including a container compressing arrangement provided with a first and a second roller, each roller having annular segments provided with specially shaped protruding elements. The device is for compression of plastic bottles as well as metal cans.

METHOD FOR RECYCLING ALUMINUM ALLOYS USING CONTAMINANT CONCENTRATION ESTIMATES FOR QUALITY CONTROL
20220111395 · 2022-04-14 ·

A method of recycling aluminum alloy wheels, the method comprising (a) providing a feed of aluminum alloy wheels; (b) fragmenting the aluminum alloy wheels into a plurality of fragments; (c) cleaning the plurality of fragments to at least partly remove at least one contaminant element therefrom; (d) determining a contaminant concentration estimate for each contaminant element in the plurality of fragments; and (e) operating a data processor to either approve or reject the plurality of fragments, based on an aggregate contaminant concentration calculation. When the plurality of fragments is approved, they may be provided to a downstream recycling process. When the plurality of fragments is rejected, they may not be provided to the downstream recycling process without further cleaning.

Fluidized bed opposed jet mill for producing ultrafine particles from feed material of a low bulk density and a process for use thereof

In consideration of increasing throughput rate of a stable operating process as well as making the process energy-efficient, the aim is to optimise a fluidised bed opposed jet mill and a dedicated process to produce ultrafine particles from a feed material of low bulk density with a housing in vertical design, with a product feed point and a product discharge, with a grinding zone located in the lower area of the housing which has grinding nozzles spaced evenly around the circumference whose jets intersect at one central point and with a classifying device installed in the upper area of the housing. This is achieved by the feed material dosed to the mill from the bottom into the mill sump as a gas-particle mixture, whereby a deflector hood is located above the feed point and below the grinding nozzle level, and the grinding gas nozzles designed to be flush with the walls.
