Paper Pulp Making Series Deflaker Double Discs Paper mill deflakers break up fiber bundles and clumps in pulp to create a uniform, dispersed stock, improving paper quality and machine runnability by preventing defects without cutting fibers or significantly reducing strength. They're used for various pulps (recycled, kraft, mechanical) to enhance pulp uniformity, improve beatability, and reduce flakes, ensuring a smoother paper sheet with fewer coarse spots, especially important in producing tissue and fine papers.
