Drum Pulper For Waste Paper Recycling Line
The drum pulper is a core piece of equipment in waste-paper pulping lines, designed for the integrated, continuous high-consistency pulping and coarse screening of unsorted mixed waste paper. It operates by lifting the waste paper as the drum rotates and then allowing it to fall freely; the resulting impact and the friction between fibers effectively break down the material.00
Drum Pulper Instructions
High-consistency pulping: Waste paper enters the rotating drum, where lifting flights raise and drop the material, facilitating high-consistency frictional defibering.
Axial transport: The drum rotates at an incline, advancing the material toward the screening zone.
Dilution and screening: Dilution water passes through the screen apertures to wash the pulp; accepted pulp enters the pulp chest, with its consistency reduced to 3%–5%.
Rejects discharge: Large contaminants are conveyed to the end of the drum and discharged.
Continuous operation: Feeding, pulping, screening, and rejects removal occur simultaneously.
