Parason Twin Disc Refiner™
Twin Disc Refiner delivers precise fiber development with dual refining zones.
Twin Disc Refiner delivers precise fiber development with dual refining zones.
The Parason Tri Disc Refiner® delivers high-intensity fibrillation and controlled fiber development through its advanced multi-disc geometry.
Engineered for demanding stock preparation environments, this refiner provides precise control over refining intensity, enabling consistent pulp quality across diverse fiber furnishes while significantly reducing specific energy consumption per ton of production.
The Parason Tri Disc Refiner® represents an evolution in refining philosophy—combining proven disc refining principles with innovative engineering to deliver superior fiber development at lower operating costs.
Three refining surfaces working in sequence deliver higher treatment intensity per pass, reducing the number of refining stages required.
Optimized chamber geometry ensures maximum fiber contact with active refining surfaces, improving treatment uniformity.
Splined shaft technology enables precise, floating rotor movement that maintains consistent gap across both disc faces.
60% lighter rotor design reduces inertia and no-load power, directing more energy into actual fiber development.
In papermaking, refining transforms raw fiber into a material capable of forming strong, uniform sheets. The quality of this transformation determines everything that follows.
Refining is the only irreversible process in papermaking that physically modifies fiber structure—directly determining tensile, burst, and tear properties of the final sheet.
Precise application of compressive and shear forces develops fiber fibrillation and flexibility, creating the bonding potential essential for sheet formation.
Uniform disc gap across the refining zone ensures every fiber receives consistent treatment, eliminating over-refining and under-refining variations.
Refining quality cascades through the entire process—affecting dewatering, pressing efficiency, drying energy, and ultimately product consistency and customer satisfaction.
Multi-disc design maximizes fiber treatment per pass, developing optimal bonding potential.
Balanced disc loading ensures consistent fiber treatment across the entire refining zone.
Optimized flow dynamics and larger refining area lower specific energy per ton refined.
180% larger opening area compared to conventional refiners for enhanced throughput.
Trusted across writing, printing, packaging, and specialty grades worldwide.
