At the heart of Leizhan’s design philosophy is a commitment to maximizing refining consistency while safeguarding fiber integrity and production efficiency. Traditional double disc refiners often rely on fixed-disc, single-gap designs that subject pulp fibers to uneven shear force distribution, leading to over-cutting of short fibers, insufficient fibrillation of long fibers, frequent unplanned downtime for disc replacement, and a persistent gap between targeted and actual pulp freeness control. Leizhan’s Double Disc Refiner disrupts this paradigm through a brilliantly optimized dual-rotating disc and dynamic gap self-adjustment system. By driving both refining discs in opposite directions at independently calibrated rotational speeds and applying real-time hydraulic pressure regulation across the full refining zone, the Double Disc Refiner harnesses uniform, multi-angle shear and friction action across every fiber bundle. Fibers are gently fibrillated rather than randomly cut, while pulp beating degree is controlled with micron-level precision to match the exact requirements of different paper grades, from high-strength packaging paper to ultra-smooth cultural paper.

 

Complementing the dual-rotating disc assembly is Leizhan’s specially engineered segmented alloy refining disc and cooling lubrication system. Designed through rigorous computational fluid dynamics (CFD) simulation and on-site pulp performance validation, the segmented disc delivers targeted tooth profile distribution matched to specific pulp types (virgin wood pulp, recycled pulp, bamboo pulp, etc.) while the closed-loop cooling system maintains stable disc temperature even during continuous 24/7 high-load operation. This dynamic performance prevents fiber thermal degradation and uneven wear of refining teeth, even when processing highly variable recycled pulp batches with wide fluctuations in fiber length and contaminant levels. The result is an exceptionally wide operating envelope characterized by short retention time, consistent pulp freeness output, and uninterrupted fiber refining performance across even the busiest high-speed paper machine schedules.

 

Embrace the future of high-precision pulp stock preparation. Equip your mill with Leizhan’s Double Disc Refiner and experience the transformative difference of unmatched fiber quality consistency, exceptional disc service life, and unmatched operational cost savings. Your customers will see the quality in every uniform, high-strength, defect-free sheet of paper; your bottom line will reflect the wisdom of your choice.
