The Arc Screen’s core innovation lies in its curved screen plate design, combined with advanced fluid dynamic optimization. Pulp enters the screening chamber under controlled pressure, forming a uniform, thin layer as it flows across the curved screen surface. Leveraging both gravitational force and centrifugal motion, the accepted fibers pass rapidly through the screen slots to continue to the next stage, while impurities—such as coarse debris and stickies—are directed downward along the arc of the screen for efficient removal.

In waste paper processing lines, the Arc Screen is commonly installed as a primary coarse screening unit after the pulper, effectively removing large contaminants like plastic fragments and metal particles. In bleached pulp or chemi-mechanical pulp production systems, it serves as a fine screening solution, eliminating fine sand, uncooked fiber bundles, and other minute impurities to safeguard pulp cleanliness. Operational data from customer sites indicates that adopting Leizhan’s Arc Screen has reduced fiber loss rates by over 15%, delivering a marked improvement in overall economic performance.

Leizhan remains committed to advancing pulping equipment technology. We warmly welcome partners worldwide to reach out for inquiries and collaboration, working together to explore innovative solutions for the evolving paper industry.
