<p>The material separation process takes place by machine by comminuting (1) the objects (G) in the mixture so that particles of either non-metallic or metallic material are formed. The particle mixture is subsequently screened (2) of fine parts and then separated (5) electrostatically into a non-metallic (N) and a metallic (M) granulate fraction. The material separation takes place with a high degree of separation, i.e. pure granulate fractions (N) and (M) are produced with only small residual parts of the respective other material. Applications of the process on different kinds of piece goods made of composite material with non-metallic and non-magnetic metal portions are described, such as bottle tops, defective incandescent or fluorescent lamps, processing waste or manufacturing waste of composite materials, for example lined metal foil or aluminium sandwich plates. <IMAGE></p> |
