An apparatus for producing pozzolanic material from consumer waste includes a glass separator unit to remove glass material from the waste and a size reduction unit downstream the glass separator unit. The glass separator unit includes a tubular outer member and an inner helical member extending inwardly from the inner surface of the tubular outer member and defining an open central bore. The tubular outer member and the open central bore define respective coaxial longitudinal axes that are disposed at an angle relative to a horizontal reference plane, with the inlet higher than the outlet. Non-glass/non-ceramic material is output through the open outlet end of tubular outer member utilizing a flow of water. The glass/ceramic material is output to the size reduction unit through the open inlet end of the tubular outer member utilizing the rotating inner helical member of the glass separator unit.

Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. Shredded matter, or ASR, is sent through a series of sorters before reaching a system that separates out copper bits. The system utilizes a pair of conveyor belts; one for de-watering and removing most of the plastic and glass particles and a second below the first for separating the copper bits. The second conveyor belt has a belt with a particular tooth pattern and material softness, and is set at a slight uphill incline angle. Water is delivered from the top down the slope and the belt successfully transports mostly just copper up and over a top edge to a collection bin. A cascading series of pairs of conveyors may be used to ensure nearly complete recovery of the copper.

A method for recovering metals from waste in which material is screened to leave a nonfibrous feedstock, the nonfeedstock is comminuted with a mill (e.g., a ball mill or rod) to liberate, flatten and separate the nonfibrous feedstock to obtain a mix of a metal fraction and residue, and the metal fraction and the residue are collected. There is a system employing the same to treat such materials.

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.

A shredder dust treatment method is provided wherein non-metal dust which is further pulverized into a small particle size in a pulverizing step S10 through a crushing step S1 of crushing wastes such as waste automobiles, waste home appliances, and waste office furniture into a predetermined size, an iron component separation and collection step S3 of separating and collecting an iron component, a non-ferrous component separation and collection step S4 of separating and collecting a non-ferrous component, a metal component separation and collection step S5 of sorting a metal component, wind power sorting steps S2, S6, S8, and S9 of sorting floating fibrous dust and a settled crushed material by wind power, and a shredding step S7 of shredding the settled crushed material into a predetermined size is separated into metal scraps such as copper, aluminum, and iron, fibrous dust, and particulate dust in a separating step S11.

A method and apparatus to reclaim metals from scrap material such as automobile shredder residue (ASR) that, after separating out light density components, separates out friable material such as rock and glass by crushing and screening operations to generate a high metal content product.

A method for preparing clean aggregate from a waste stream including sizing the incinerator combined ash to recover a first material; wet screening the first material with a first screen to recover the material of disparate sizes; and processing each of the groups.

A method for recovering metals from waste in which material is roughly or coarsely separated to leave a fibrous feedstock, the feedstock is comminuted with a mill (e.g., a ball mill) to liberate and separate the fibrous feedstock to obtain a mix of a metal fraction and residue, and the metals fraction and the residue are collected. There is a system employing the same to treat such materials.
