PROCESS FOR SEPARATION OF CELLULOSE AND OTHER ADHESIVE MATERIALS DURING RECYCLING OF WASTE PLASTICS, PARTICULARLY, MIXED PLASTICS

摘要

The recycling process involves foils and scraps of thicker plastic sorted out in a pre-sorting phase being ground into flakes or particles and refining them with water in a toothed disc refiner (26) whose teeth are engaged with each other with the teeth spaced out on concentric circles, The gaps between the teeth of one of them are of a size to allow thick solid pieces through for subsequent grinding into flakes and fine grains.
