The D-Type Hydraulic Pulper Is the First Critical Step in Waste Paper Recycling
The D-Type hydraulic pulper uses a helical rotor operating at 180-220 RPM to create a controlled vortex that separates fibers from contaminants without damaging fiber length. Unlike conventional drum pulpers, the D-shaped vat design prevents dead zones where unpulped stock accumulates, achieving over 95% defibering efficiency in a single 15-25 minute batch cycle.

FAQ
What is the optimal pulping consistency for OCC recycling?
4-6% consistency is optimal. Below 4% reduces throughput; above 6% increases motor load and defibering time.
How long do D-Type pulper rotors last?
Rotor vanes typically last 3-5 years under normal OCC processing. Annual inspection recommended with 8-12 mm clearance check.
