Due to the friction on and between the com- pacting discs, the amount of friction is determined by the distance between discs which is adjustable, the material is heated quickly, spun off and conveyed via a central downstream blower to the secondary granulator. Since the dwell time of the material in the compacting zone is only a matter of seconds, the thermal impact on the material is mini- mal contrary to extruders. Herbold Meckesheim’s developments are ground-breaking. The company has de- veloped wet size-reduction with granula- tors and made many further improve- ments to recycling techniques using state of the art equipment.
