High‑Efficiency Pulping Machine D Type Hydrapulper
The D type hydrapulper represents a significant upgrade in waste paper pulping technology. Unlike conventional round pulpers, this D type hydrapulper features a unique D‑shaped tub that changes the slurry flow pattern, bringing pulp into contact with the rotor more quickly and frequently. The result is stronger mechanical action, shorter pulping cycles, and higher throughput – all while saving energy.
Key Features of This D Type Hydrapulper
Energy‑saving VOKES rotor – The specially designed rotor enhances hydraulic circulation and fiber separation, reducing power consumption per ton of pulp.
D‑shaped tub design – In a D type hydrapulper, the flat side of the tub directs the slurry flow toward the rotor more efficiently, increasing the frequency of fiber‑rotor interactions and accelerating defibering.
Low‑pressure impurity collection zone – The rotor chamber is positioned slightly higher than the bottom of the pulper barrel. This creates a low‑pressure area around the rotor that collects heavy contaminants (stones, metal pieces, glass) without forcing them through the rotor or screen. This D type hydrapulper design significantly extends the service life of both the rotor and the extractor plate.
Adjustable rotor‑to‑screen gap – The clearance can be fine‑tuned to maintain optimal pulping performance as wear occurs.
Continuous pulping & deslagging system – When the D type hydrapulper works together with a hydrapurger, drum screen, ragger, rope cutter, and grapple, it forms a continuous system that rejects large light and heavy impurities in real time. This prevents over‑pulping of contaminants, reduces downstream equipment wear, and minimizes downtime for cleaning – boosting overall system capacity.
This D type hydrapulper is ideal for pulping OCC, mixed waste paper, newspaper, and even some high‑strength kraft grades. It is widely used in linerboard, testliner, corrugating medium, and tissue mills.
