Method and device for the processing of a mixture of waste bodies made of polyethylene terephthalate and of polyvinyl chloride, and application to the processing of bottles made of these materials

摘要

The invention relates to the separation of polyethylene terephthalate and polyvinyl chloride in order to obtain particles which can be recycled. The mixture of bodies or of particles obtained by grinding the mixture of the PET and PVC waste is subjected to impact grinding followed by particle-size classification, optionally repeating the operations. The figure shows a flow diagram of the method, which includes the implementation of successive grinders 1, 3, 6 alternating with successive screens 2, 4, 5, 7. The invention is applied in particular to the processing of a mixture of PET and PVC bottles. IMAGE
