<p>The invention relates to a method for comminuting and cleaning waste plastic, particularly mixed plastic (MKS) with the following steps: a compacted material, particularly an agglomerate, is produced from film scraps or from film remnants, which are comminuted into flakes, and/or from thick-walled plastic parts, which are chopped up into chips. The compacted material is introduced into a disc or drum refiner and is ground therein in the presence of water. The portion of compacted material of the stock located inside the refiner is at least 10 percent by weight. A fine-grain fraction is removed from the ground stock exiting the refiner. The remaining ground stock is washed and either mechanically dewatered and dried or is ground once more in another refiner stage in the presence of water after which it is dewatered and dried.</p> |
