Method and device for treating plastic based waste

摘要

A preparation plant for plastic waste containing cellulose, foamed material, metal, dirt particles and moisture has an initial shredding stage followed by separation of non-synthetic particles and fine grinding in an air stream in an impact mill. The exit of the impact mill is connected to a settling chamber which has a draw-off for the grinding air and vapourisation products near the top. The bottom of the settling chamber is fitted with a cellular rotary air lock for the removal of the ground-up waste material.
