Low consistency refiners
Refining that delivers consistent quality and cost efficiency
The Valmet Conical Refiner Conflo is designed for low consistency refining across mechanical, chemical, and recycled fiber applications. With precise gap control and optimized flow dynamics, it ensures stable operation, uniform fiber treatment, and improved paper quality—while reducing energy consumption and operating costs.
How the refiner works in your process
The refining process in the Valmet Conical Refiner Conflo takes place between specially tailored fillings, where precise gap control ensures consistent fiber treatment. Its cantilevered design—with a fixed stator and a uniformly moving rotor—maintains a stable clearance, which is essential for uniform refining results. Centrifugal force enhances fiber coverage across the bars, while the extended refining zone increases retention time, allowing for optimized fiber bonding and flexibility. This results in pulp that supports high-quality paper production with improved runnability and fewer web breaks.
What makes the RF-5 model technically outstanding?
The RF-5 is the largest model in the Conflo series, designed for high-capacity low consistency refining. It operates within a consistency range of 2–6% and supports motor powers up to 3000 kW, with a speed range of 330–450 rpm. Its robust design ensures stable operation even under demanding conditions, while the wide selection of filling patterns allows customization. The RF-5 integrates seamlessly with modern automation systems, offering flexible control and easy maintenance – making it ideal for large-scale pulp and paper operations.
