Abstract: 896,852. Separating solid materials. INTERNATIONAL SALT CO. Aug. 31, 1959, No. 29606/59. Class 117. Fragments of material, e.g. plastic or metal scrap, mixtures of metals, having different heat-absorptive and/or reflective characteristics, are separated by exposing them to heat causing them to be differentially heated, delivering the heated mixture to a heat sensitive thermoplastic surface whereby the fragments adhere to the surface in different degrees, and thereafter activating the surface so as to separately discharge the fragments therefrom. In Fig. 1 material 12 from a hopper 10 passes to a rotary cylindrical screen or heater 18 housing infra-red lamps 22, and the differentially heated mixture passes to a feeder screen 26 and shoot 28 and to an endless conveyer belt 25 coated with a suitable thermoplastic substance. Relatively hot fragments stick to the conveyer and pass to a receiver 36 whereas the cooler particles are ejected to a receiver 32. A scraper is located above the receiver 36 and a rotary wire brush 38 sweeps the return run of the belt. Apparatus is described for coating the belt with thermoplastic material and for keeping the surface of the thermoplastic layer clean. Instead of infra-red lamps the heating of the cylinder 18 may be effected by a fuel gas burner applied to its outer wall, or by electric heating coils in its walls. Alternatively the mixture may be heated by a rotary kiln fired by a fuel burner. In a further embodiment the mixture is heated dielectrically during its travel on a conveyer by passing between a pair of plate electrodes, or by passing below a series of rod electrodes.
