The document describes the ANDRITZ FibreFlow drum pulper, which is used to pulp and separate coarse contaminants from recovered paper with minimum fiber loss. Key benefits include high production capacity and low power consumption in a single unit, gentle pulping that separates fibers from contaminants, and reliable mechanics with low maintenance needs. The drum rotates and uses dropping and falling motions to defiberize materials while continuously removing debris and accepting fibers.

FibreFlow drum pulper
Minimum fiber loss at lowest power consumption
Benefits
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. 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.
