High-Speed Stock Washer For Pulp Making
A high-speed stock washer is a piece of equipment applied in waste-paper deinking and pulping lines that integrates both washing and thickening functions. In traditional processes, washing and thickening are two separate stages; the high-speed pulp washer combines these two operations into a single unit.
Stock Washer Workflow
Thin-layer pulp application: Low-consistency pulp is sprayed into the nip between a high-speed mesh belt and the breast roll, forming a thin layer.
Breast roll pressing: Centrifugal force and pressure from the grooved surface remove water, fillers, and ink particles.
Displacement washing: The pulp layer is sprayed with fresh water, which displaces and replaces the residual contaminated liquid.
Couch roll pressing and discharge: A second stage of pressing removes further water; a doctor blade then scrapes the pulp off, resulting in an output consistency of 8%–15%.
Wire belt cleaning: The mesh belt is cleaned by high-pressure, oscillating water jets to restore its permeability before it re-enters the cycle.
