| description | Method for comminuting and cleaning waste plastic, in particular, mixed plastic (MKS) with the following steps: a compacted material, especially, an agglomerate is produced from film scraps or film remnants comminuted into flakes and/or thick-walled plastic parts chopped up into chips, the compacted material is introduced into a disc or drum refiner and is ground therein in the presence of water, wherein the portion of compacted material of the goods located in the refiner amounts to at least 10 percent by weight, a fine grain fraction is removed from the ground stock exiting from the refiner, the remaining ground stock is washed and either mechanically dewatered and dried, or pulverized again in a further refiner stage in the presence of water, and subsequently dewatered and dried. |
