Recycled Fiber Systems

ANDRITZ offers excellent FibreSolve LC pulping systems including detrashing as well the FibreFlow drum pulper for slushing highly contaminated furnishes with superior performance.

Equipped with an optimized rotor and vat, ANDRITZ LC pulpers achieve high pulping efficiency with gentle treatment of fibers. Combining the FibreGuard detrashing system, even pulps containing a high level of contaminants can be handled with ease. Specialized materials, low rotational speeds, and fast reject removal maximize the lifetimes of the individual machine components.

High production capacity and low power consumption due to the combination of pulping and screening in one compact unit make the FibreFlow drum pulper your ideal choice. As a result, less equipment is required in the pulping and detrashing process. The drum removes contaminants in the first stage of the process without generating fines or damaging fibers.

AhlCleaners RB are cleaners with a larger diameter that reliably remove impurities such as coarse sand, metal, glass, and other heavy particles. These high-density cleaners are equipped with junk traps to minimize fiber losses. AhlCleaners SC133 and PrimeClean TO are highly efficient in removing small impurities. The design features low-pressure drop resulting in minimum power consumption, while pressurized ejection of impurities prevents air from entering accept and reject flows. Specially designed cones in later cleaning stages reduce fiber losses. Light particles such as polystyrene foam, waxes and hot melt adhesives can be efficiently removed by light weight cleaners LW80 and LW90.

ANDRITZ is well known with a huge number of pressure screens installed in numerous stock preparation lines worldwide. Different types of ModuScreens are perfectly suited for any RCF application. The PrimeScreen X stands for significant improvements in energy efficiency, screening performance, and maintainability thanks to top-feed stock inlet, the PrimeRotor, optimized screen basket height-to-diameter ratios, and easier maintenance. Various rotor and screen basket types and combinations can be applied depending on specific process requirements.

The ModuScreen D is a proven coarse screen that achieves top deflaking performance and operates trouble-free, especially when processing low-grade furnish. The ModuScreen TD is a continuously operating screen which handles screening, deflaking, fiber recovery, and reject dewatering in a single compact unit.

The PrimeFilter D brings together several key technological innovations to improve throughput and reduce both investment and operating costs. HHw technology ensures advanced feeding and optimum flow conditions within the filter. Thus, the disc filter can handle higher feed consistencies and pulp with a higher freeness even in the most demanding applications. CC bagless sectors offer significant improvements in terms of operation thanks to very homogenous fiber mat build-up as well as fast mat knock-off. The special construction of the sectors eliminates the need for a filter bag and reduces maintenance to almost zero. The innovative double sealing arrangement is easily accessible and ensures higher reliability with superior filtrate quality.

ANDRITZ dispersing minimizes the size of contaminants and improves the physical fiber properties. Ultra High Dispersion (UHD) is a technological add-on that is perfectly suited for ANDRITZ or other conventional dispersing systems. A dewatering plug screw feeder makes it possible to operate the disperser at higher consistency. This has the result that there is less water in the pulp to heat, thus considerably reducing the necessary energy input. 

ANDRITZ’s proven TwinFlo disc refiners and innovative Papillon refiners with cylindrical refining zone are perfectly suitable for the production of all paper grades.

To enable optimum development of the fiber potential, ANDRITZ applies the TwinFloPrime double-disc refiner with its sturdy machine design that guarantees top reliability and has proven successful worldwide. Plates can be changed quickly thanks to the “swing-door” concept for the shortest possible downtimes and lowest maintenance costs.

The Papillon refiner concept offers significant improvements in energy consumption thanks to the compact rotor design compared to competitive refiners in similar applications. Efficient treatment of the fibers throughout the entire refining area is a precondition for superior paper properties. The Papillon refiner has proven its unique design, particularly in virgin and annual fiber applications.
