In a facility and a method for separating glass residues from PVB-film, comminuted material is passed through several process steps, where treating with beaters (12) in a chamber (2) is effected in one of the first steps. At the discharge end (18) of the chamber there is arranged a separation, as heavy particular material can be discharged through a perforated bottom section (19) in the chamber (2). Through an air inlet (22) at the side (15) of the chamber, air is drawn in induced by a ventilator-like impeller rotor (28) drawing air in through a central opening (26) spaced apart from the bottom section (19). Thereby, light film-like materials are carried away from the heavy particles.

This process is intended to recover polypropylene and polyethylene that are not filled or that are less than 20% filled in a mixture (12) of fragments (14) of materials obtained directly by shear milling of articles. It comprises a first step of milling the fragments of the mixture (12) by means of a hammer mill (16) equipped so as to cause the fragments of the mixture (12), mainly consisting of polyethylene and polypropylene fragments, to break into grains, so that they retain dimensions above a predetermined threshold and a second step of separation by screening to extract the fragments having dimensions above the predetermined threshold.

A crushing machine for comminuting laminated glass, particularly windshields for cars, consists of a chamber with cylindric wall (24) in which is suspended a rotor (28) with pivotably beaters (50). Plural layers of laminated glass are fed through a feeding opening (20) through rubber rollers (22) which form an almost airtight lock into the crushing chamber. At the inner side of its wall (24), the chamber is provided with a number of evenly distributed ribs (54) to be impacted by laminated glass pieces, which are subsequently further comminuted by the beaters (50). The crushing chamber is provided with a slot-formed discharge opening (34) which may be varied in width. Outside the discharge opening (34), there is mounted a collecting containing (36) provided with subpressure. Due to naturally occurring leaks in the wall (24) of the crushing chamber, including the feeding opening (22), there will be a continuous flow of air out through the opening (34), why the material will eventually be conducted therethrough and collected in a container (36). From here, the material may leave the container (36) through an aperture closed by a flap (38). With the crushing machine according to the invention, there may be achieved a complete comminution of laminated glass material and separation of glass from the plastic film in one step and so that the finest glass particles have a size in the order of 0-3 millimeters.

The invention relates to a process for recovering monomeric units of a nylon from carpet material, said carpet material comprising fibres containing said nylon bound to a backing containing one or more non-nylon components, the carpet material containing between 15 and 35 wt.% of said nylon, which process comprises the steps of: a) mechanically separating the carpet material into an enriched carpet mixture containing between 35 and 55 wt.% of said nylon and into a depleted carpet mixture having a lower content of said nylon than the carpet material; b) exposing the enriched carpet mixture to conditions at which depolymerisation of said nylon is effected.
摘要:
A method of disassembling a waste refrigerator having foam resin used as insulator, comprising the steps of cutting off the insulated cabinet body of the refrigerator into pieces of specified size and shape, pressingly passing the pieces between a pair of compression rolls disposed opposite to each other to peel off and separate incompressible platy matters accumulated on at least one surface of the pieces so as to provide the foam resin, and pressingly passing the foam resin (301) between the pair of compression rolls (331, 332) disposed opposite to each other to leak out and collect the foam gas contained in the foam resin, whereby the foam gas in the insulator can be collected in the state of high density by using a small-sized equipment at a low cost.
