Verfahren und Anlage zum sortengerechten Separieren von Kunststoffen aus aufbereiteten Kunststoffgemischen

摘要

The present invention relates to a process by which plastics are separated from recycled plastic mixtures according to type, whereby the plastic parts freed from metals are taken on fast moving conveyor belts isolated as a fine, light and/or coarse material and the plastic parts to be selected are removed from the plastic flow in at least one optomechanical sorting device of activatable ejectors. With the goal of providing clean materials cheaply for further recycling all those plastic parts that do not belong to the predominant group of materials in the plastic flow are actively separated from the plastic part flow, in an initial process step (5, 5', 6, 6') at minimum one optomechanical sorting device, using individually controlled ejectors (for example nozzles) and in a second process step (56, 57; 7, 8) from one of the secondary plastic flows at, at least, one other optomechanical sorting device the predominant plastic parts contained in the plastic flow or a part definable according to optically identifiable criteria of the same is actively separated.
