The most striking feature of Leizhan’s D Type Hydrapulper is its “D”-shaped tub. Traditional pulpers are circular, which often results in a “vortex” effect where the stock rotates in a predictable circle, leading to dead zones and slower disintegration. The D-shape design changes the flow pattern of the paper stock. When the slurry hits the flat wall of the “D,” the vortex is broken, and the material is diverted back toward the center of the rotor. This creates a high-turbulence environment that forces the paper to contact the rotor more frequently, significantly shortening the pulping time.

 

Features of Leizhan’s D Type Hydrapulper

1. Enhanced Pulping Efficiency: Due to the unconventional turbulence created by the D-shaped tank, the D Type Hydrapulper can disintegrate waste paper much faster than a conventional pulper. This leads to an increase in capacity without requiring a larger footprint.
2. Energy Savings: One of the primary concerns for modern paper mills is power consumption. Because the D Type Hydrapulper increases the frequency of contact between the fiber and the rotor, it achieves the desired consistency in less time. This results in a reduction of energy consumption per ton of pulp by approximately 15% to 20% compared to traditional models.
3. Optimized Rotor and Sieve Plate: Leizhan equips these machines with high-performance rotors (often the S-Shape or Energy-saving type) made of wear-resistant materials. The gap between the rotor and the sieve plate is easily adjustable, ensuring that fibers are separated effectively while contaminants (like plastics and tapes) remain intact for easier removal.

 

In an era where paper mills must balance high output with environmental and energy constraints, the Leizhan D Type Hydrapulper stands out as an essential tool. Its simple yet brilliant change in geometry—turning a circle into a “D”—has transformed the efficiency of the pulping station, making it a staple in modern mills across the globe.
