In the papermaking industry, the primary function of a fiber deflaker is to further break down fiber bundles, pulp clumps, paper fragments, wet-strength paper lumps, and fiber bundles found in screen rejects—ensuring uniform fiber dispersion—while minimizing significant alterations to fiber morphology, unlike what occurs in a refiner.

 

Main Functions of Pulping Line Fiber Deflaker

 

1. Fiber defibering: Breaking up fiber bundles and clumps into individual or more uniformly dispersed fibers.
2. Pulp clump dispersion: Eliminating residual pulp lumps and wet paper clots remaining after initial pulping.
3. Fiber recovery from rejects: Re-defibering fiber-containing material discharged from coarse and fine screening stages.
4. Improving pulp uniformity: Reducing fiber flocculation in the pulp to enhance the formation uniformity of the finished paper.
5. Reducing downstream refining load: Performing defibering prior to feeding the pulp into the refiner as required.
