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.
FUNCTION & APPLICATION
The drum is a rotating device consisting of two sections (pulping and screening) and separates the debris from the fibers with minimal fiber loss. In the pulping section wetting, chemical impregnation and defiberizing take place. Fiber recovery and reject separation are done in the screening section.
Best accept quality – improved ink detachment and brightness gain – thanks to gentle pulping concept and efficient coarse contaminant removal with minimum fiber loss.
Highest availability due to single drum machine design with no internals creating wire build-ups
Reliable and proven mechanics
Lowest operating costs thanks to minimum maintenance and efficient single drive
