Quality craftsmanship in manufacturing & proven performance at customer sites

Gentle fiber treatment for recovered paper at 15-18% consistency, with effective contaminant separation and minimal fiber damage.

Quality craftsmanship in manufacturing & proven performance at customer sites
The Sharp Edge Drum Pulper PDP delivers gentle yet effective pulping for recovered fibers — achieving high consistency processing while preserving fiber quality.
Engineered for contaminated recycled paper, it separates fibers from contaminants without shredding, ensuring low fiber loss and superior pulp quality.
Gentle pulping for maximum fiber recovery
Careful pulping preserves fiber length and quality for better paper
Designed for highly contaminated recycled paper and waste
Operates at just 15-25 kWh/t — significantly below conventional pulpers
Non-shredding design keeps contaminants intact, reducing fiber escape
Optimized drop zone for effective fiber release
Baled or loose waste paper enters the rotating drum
Sharp edge lifters create optimal drop height for fiber separation
Fibers release at 15-18% consistency while contaminants stay intact
Good fibers exit through screen, rejects discharge separately
