Abstract

Appts. to condition waste paper for recycling, where a solvent is used to dissolve the paper, has a separator for the removal of heavy impurities followed by a fiberiser fitted with an outlet for usable material and outlet channels for both light and heavy material to be sepd. The outlet for heavy matter to be sepd. leads through a channel to a point in the equipment in front of the separator. System ensures an even flow of material through the equipment, and prevents the risk of blockage in the outlet channel caused by heavy material.
