Recycling process for all waste plastics including mixed plastics involves milling in first stage using toothed disc refiner

摘要

The recycling process involves milling agglomerate in the presence of water in a first refining stage, washing out the fine particles, drying the residue and milling again in a second refining stage, and then drying. The first stage includes the use of a toothed disc refiner whose teeth and gaps between teeth are arranged to pass the milled grains through freely.
