Drum Pulper for Waste Paper Making Line

The drum pulper is a breakthrough solution for continuous, gentle pulping and coarse screening of waste paper under high consistency. Unlike traditional batch pulpers, this drum pulper combines pulping and preliminary screening in one rotating drum – simplifying your process flow while protecting fiber quality. Operating at 14–18% consistency, it preserves the physical properties of recycled fibers and minimizes damage to contaminants, making downstream cleaning more efficient.

Key Features of This Drum Pulper

1. Gentle high‑consistency pulping – The drum pulper operates at 14–18% consistency, which maximizes fiber liberation while keeping contaminants (plastics, staples, foils) largely intact for easier removal later.

2. Continuous operation – Material enters one end, pulp and rejects exit the other. This drum pulper runs non‑stop, eliminating idle time and boosting daily throughput.

3. Built‑in coarse screening – The drum shell has holes that allow accept pulp to pass while retaining oversized impurities. No separate coarse screen is needed.

4. Long retention time – The slow, tumbling action gives fibers ample time to deflake, yet fine fiber loss is very low.

5. Low energy & maintenance – A drum pulper requires less power per ton than high‑speed pulpers. Few quick‑wear parts and a simple design keep maintenance costs down.

6. Protects downstream equipment – By removing large contaminants early, this drum pulper reduces wear on refiners, pressure screens, and pumps.

This drum pulper is ideal for recycling OCC (old corrugated containers), mixed waste paper, and even some grades of household waste. It is widely used in linerboard, testliner, fluting, and white top production lines.
