Abstract:
A method for the recycling of all types of waste plastic, in particular mixed plastic (MP), in which compactate, in particular agglomerate, is ground from flakes or other plastic parts in at least one refiner stage in the presence of water, from which fine particles are removed from the ground material emerging from the refiner stage with the process water, the remaining ground material is washed and/or mechanically dehydrated and dried or the dehydrated ground material is again ground in another refiner stage in the presence of water and then dehydrated and dried, wherein the grinding of the compactate is performed in at least one refiner stage using a disk refiner (toothed disk refiner), the disks of which have engaging teeth, which are arranged separated on concentric circles, wherein there is a hole between neighboring teeth of a circle and the holes of a circle are each big enough that the particles to be ground or ground up to that point can pass through freely.
