A method includes one or more of the following five steps: (1) rough processing, (2) comminuting the material, (4) washing the material with acid, and (5) collecting/sorting the material to recover an aluminum product or a very pure aluminum product. A system may execute one or more of these steps to recover an aluminum product or a very pure aluminum product

A method for comminuting heat-sensitive feedstock, particularly thermoplastics, rubber, caoutchouc, and elastomers, to a particle size of less than 500 m, preferably less than 425 m. Process steps are provided to achieve an economic material processing without the use of cryogenic comminution. First, a precomminution of the feedstock to a size smaller than 4 mm is performed in a rotating comminuting device through which a first process gas PG.sub.1 flows. Then, a fine grinding is performed of the precomminuted feedstock to a size smaller than 500 m, preferably smaller than 425 m, in a rotating fine grinding device through which a second process gas PG.sub.2 flows. Whereby the temperature of the precomminuted feedstock in the outlet of the fine grinding is regulated in a second control circuit by adding water to the precomminuted feedstock before and/or during and/or after the fine grinding.

Impact reactor (1) for comminuting composite materials, comprising a cylindrical casing (2), in which a rotor (3) is arranged, and an introducing opening (9) for introducing the composite materials and an extraction opening (8) for discharging the comminuted composite materials, wherein at least one further introducing opening (10) for a cooling medium is provided.

This metal film and resin separation method is a method of putting synthetic resin waste in which a metal film adheres to a synthetic resin into a separation chamber in a casing, rotating a hammer rotor in the separation chamber, and separating and recovering the metal film and synthetic resin. While rotating the hammer rotor, the synthetic resin waste in the separation chamber is crushed, and a temperature in the separation chamber is increased to an exfoliation temperature which is higher than a normal temperature and less than a temperature at which the synthetic resin starts melting. While holding the temperature in the separation chamber at the exfoliation temperature, the synthetic resin waste is crushed and the metal film is exfoliated from the synthetic resin.

A maceration conveyor assembly feeding into a first mill of a milling tandem, where output from the mill is delivered onto another conveyor and carried to the next mill in the tandem. Low pol maceration liquid is returned to the conveyor via return lines to respective distribution weirs. Weirs include overflows which extend across the conveyor. The conveyor assembly includes an inlet end and an outlet end all supported on a supporting framework so that the assembly is inclined from the inlet end to the outlet end. The frame supports respective side walls of a conveyor trough between which travels an endless plate conveyor. The endless plate conveyor comprises interconnected perforated plates adapted to pivot relative to each other in chain like fashion so that the endless plate conveyor effectively functions as a belt conveyor having rigid plates interconnected in pivotal fashion.
