This application describes method and systems for recovering metals from metal-containing material. Some embodiments of the disclosed method include one or more of the following three steps: (1) sizing, (2) separating using the helix separator, and (3) collecting. A system can execute these steps.

A system and method for processing objects having chemical contaminates includes a shredding module arranged to shred the objects to form a plurality of shredded fragments, each having the chemical contaminates, and a separating module arranged to separate the chemical contaminates from the shredded fragments.

A waste tire resourceful regeneration treatment method is provided, including: step S1, sorting, including: sorting waste tires according to types of the waste tires to obtain target waste tires with steel wires; and step S2, bead-cutting, including: performing a bead-cutting process on the target waste tires through a bead-cutting machine, to cut the target waste tires into beads and first remaining portions separated from the beads. With respect to the method, the target waste wires with steel wires are sorted out from waste wires of different types, a bead-cutting machine is used to remove beads with steel wires from the waste tires with steel wires and separate the steel wires from the beads with steel wires, then a series of processes including cleaning, crushing, magnetic separation, fiber separation, sieving, desulphurizing, and cooling are performed to obtain recycled resources of the waste tires.

A method for processing, namely recycling, a workpiece made of electroplated plastic. In which method a coating is removed from the workpiece by a fragmentation unit by applying the electrohydraulic effect to a suspension containing plastic granules and containing coating granules. The suspension is dewatered, and a magnetic separator is used to separate the plastic granules from the coating granules by means of magnetic separation.

A modular system and process are described for recycling textile waste of various compositions into new ready to use fibers for garment manufacturing or other uses.

A system and method for freezing and breaking down tires or other materials is disclosed. The system and method for freezing and breaking down tires includes using a shredder to shred the tires, using a filter to screen the tire shreds, using a water sprayer to rinse the tire shreds, using a freezing tunnel to freeze the tire shreds before they are crushed into tire grains, using a magnet to remove any metallic fibers, filtering out any oversized tire grains for re-freezing and re-crushing, and using a separator to separate out any oversized or undersized pieces before bagging the final tire grains for re-use and recycling.

A device for processing scrap rubber has a reactor with a screw conveyor disposed inside a heating chamber, a thermal decomposition unit, burners, a condenser, a cyclone filter, and devices for discharging solid residue and removing a gas-vapor mixture. The reactor has two sections connected in parallel. The thermal decomposition unit has screw conveyors in each section, the conveyors have axial heating pipes with a coil. Along the length of the conveyors plates are arranged at the corners of an equilateral triangle in contact with and perpendicular to the side surface of the heating tube. A cylinder furnace with an evaporator and a burner is connected to the ends of the pipes. An outlet of the condenser is connected to a liquid fraction separator, inlets of the coils are connected to an outlet of the evaporator, and an inlet of the evaporator is connected to an outlet from the separator.

A plant for recovering and treating residues from crushing scrap is provided. The plant includes a first plant part and a second plant part. The first plant part is provided with crushing and separation means configured to extract ferrous materials, non-ferrous metals and plastic materials from the residues from crushing. The separation means are provided with a granulator system configured to reduce, in dry mode and without pre-screening stages, the residues from crushing into a stream of granular material. The second plant part is provided with means to treat and size the plastic materials configured to transform the plastic materials into additive material to be used, in particular, in iron and steel plants such as blast furnaces, electric arc furnaces or suchlike. The means to treat and size the plastic materials includes a dry system for cutting and/or grinding the plastic materials.
