Efficient pulping of recycled and virgin fiber pulps

Outstanding devices to des-integrate papers and remove contaminants

ANDRITZ pulping systems provide outstanding units to des-integrate recovered papers and virgin pulp and to remove contaminants from pulp. Many references worldwide for all kinds of applications and in low- and high-consistency operating ranges demonstrate high performance and efficient slushing of the individual pulping systems.

The ANDRITZ FibreFlow drum pulper is applied for all kinds of recovered papers and is the preferred choice for continuous pulping. With an installed base well over 200 units globally this pulping system represents gentle pulping and efficient coarse contaminant removal with minimum fiber loss and low power consumption.

The low-consistency pulping system comprises the FibreSolve FSR pulper type, which is utilized for lower and medium recovered paper grades. Two different detrashing systems, the FibreGuard FG and the FibreSlush FS system, are used to separate fibers from impurities. The FibreWash drum FWD recovers fibers and pre-dewaters rejects as final stage in these continuous pulping systems.

The high-consistency pulper FibreSolve FSH offers efficient pulping for recovered papers and virgin pulp grades and is operated in batch mode. Depending on the amount of coarse contaminants in the raw material, two different discharge systems are applied, the FibreBatch FB system with the FibreWash drum FWD and the FibreEx FEX system.
