Leizhan, a leading Chinese pulping equipment company, has demonstrated through over forty years of dedicated focus that true improvements in pulping efficiency begin with a profound understanding of the fiber’s microstructure.
In waste paper pulping and virgin pulp processing, the double disc refiner undertakes the core mission of fiber development. Unlike single-disc or conical mills, dual-disc refiners employ a dual-rotor counter-rotating design, creating a high-intensity shear zone between the two discs.
1. Bidirectional Shearing, Doubling Efficiency: Traditional single-disc mills rely on unidirectional rotation, while the Leizhan’s double disc refiner design subjectes the pulp to bidirectional shearing force as it passes through the precise gap between the discs under the combined effects of centrifugal force and feed pressure. This means that with the same energy consumption, fiber fibrillation is improved by more than 30%.
2. Constant Power Control, Stable Quality: “Three parts paper making, seven parts pulping”—this is an old adage in the paper industry. The Leizhan double disc refiner series is equipped with an automatic constant power control system that automatically adjusts the disc gap according to pulp concentration and flow rate, ensuring a constant fiber processing intensity (SEL, Specific Edge Load) per unit energy consumption, avoiding over- or under-refining. This is particularly important for producing high-grade toilet paper and packaging paper.
3. Full Raw Material Adaptability: Whether it’s chemical wood pulp, mechanical pulp, waste paper pulp, or straw pulp, the double disc refiner can be precisely adapted by changing the refiner plates of different tooth shapes. Leizhan offers a full range of specifications from φ380mm to φ1100mm, with a capacity covering 600-800 tons/day, meeting the needs of all scenarios from specialty paper to large-scale packaging paper production.
