Heavy Impurity Cleaner for Waste Paper Pulping

High-Efficiency Heavy Impurity Cleaner

In the waste paper pulping line, the heavy impurity cleaner performs an indispensable function: effectively separating out heavy contaminants—such as grit, metal fragments, and glass shards—that have a specific gravity significantly higher than that of the fibers, before the pulp enters the pressure screens, refiners, and paper machine.

Heavy Impurity Cleaner Features

Single-pass centrifugal separation: Utilizing specific gravity differences, the slurry rotates within the cone; heavy impurities are thrown against the wall and discharged, while fibers rise through the center. Separation is achieved in a single pass, eliminating the need for rejects treatment.

Wear-resistant ceramic with long service life: The cone features an alumina ceramic lining with a smooth, highly wear-resistant surface; key components have a lifespan of 7–9 years, and the split-body design facilitates easy disassembly and replacement.

Low fiber loss: A water seal formed by balance water or back-flush water prevents fibers from entering the rejects tank; multi-stage cleaning combined with a fiber recovery unit recovers fibers from the rejects.

No moving parts, automatic reject discharge: The absence of rotating parts results in a low failure rate; a pneumatic discharge valve operates on a timed automatic cycle, enabling continuous, unattended operation.

Protection for downstream equipment: Installed after pulping and before screening/refining, it removes grit and metal contaminants early on, protecting screen baskets, refiner plates, and forming fabrics.

If you are troubled by heavy impurities in your pulp, or wish to optimize the fiber recovery rate and energy efficiency of your existing de-shiving system, please feel free to contact us for more details about heavy impurity cleaner.
