METHOD AND EQUIPMENT FOR SEPARATING PLASTIC

摘要

PROBLEM TO BE SOLVED: To separate chlorine-containing plastics from-plastic wastes with high precision. SOLUTION: The wastes mainly composed of the plastics are crushed by a crusher 1 to 1 to 15 mm. The plastics are then classified by a zigzag air separator 2 to the plastics 9 below 200μm and the plastics 8 of a thickness exceeding 200μm. The thick plastics 9 and thin plastics 8 are then separated respectively by air table type dry process specific gravity shape separators 31 and 32 to heavy objects (chlorine-containing plastics) 101 and 102 and light objects (plastics not containing the chlorine) 111 and 112.
