<p>In the processing used paper, for recycling, the coarse fraction (4) from the sorting stage is passed to a reduction stage (5), which has a more intensive mechanical action than the mixing operation in the drum (1). The forces and operating times of the reduction stage (5) are set so that the paper material which is difficult to break down is delivered in a fraction of paper material (6) which is hard to dissolve but which can be pumped. Also claimed is an assembly where the coarse fraction (4) is passed to a stage where it can be reduced to a fraction of waterproof paper which can be pumped.</p> |
