The ANDRITZ FibreFlow Drum pulper is used for fiber slushing and separation of coarse contaminants for all kinds of recovered paper. High production capacity and low power consumption in a single unit make the FibreFlow drum pulper the preferred choice for continuous pulping. Wastepaper furnishes are de-fiberized by means of continuous turnover (via dropping and falling) that gently separate fibers from contaminants, which are rejected continuously and automatically.
