METHOD OF PROCESSING MIXTURES OF PLASTIC MATERIALS AND PLANT FOR PROCESSING OF MIXTURES OF PLASTIC MATERIALS Russian patent published in 2000 - IPC

FIELD: reprocessing of plastic materials containing foreign components. SUBSTANCE: in method of processing mixtures of plastic materials, particularly, mixtures of plastic materials from household wastes, processed material is comminuted and obtained product is agglomerated. Magnetic components are withdrawn from mixture. During agglomeration, volatile substances are withdrawn by means of suction devices. Agglomerated material is dried and screened. Plant for processing of plastic material mixtures containing foreign components has devices for comminution, agglomeration of material and means for withdrawal of fine fraction from agglomerate. Plant has magnetic separator, exhaust system for suction of volatile substances in agglomeration and drying section for agglomerated material. Means for withdrawal of fine-grained fraction from agglomerate is made in the form of fine-mesh screen for screening of fine-grained fraction. High-quality plastic material agglomerate is produced with low power consumption and may be used on industrial scale as substitute for primary fuel, initial material for manufacture of building parts, etc. EFFECT: higher efficiency. 37 cl, 11 dwg
