The Hydrapurger is a dynamic screening and separation device integrated into the pulping line. It uses the principles of hydraulic flow, screening, and adsorption to differentiate and remove contaminants from the slurry. In Leizhan’s pulp line, the Hydrapurger targets both light impurities (such as plastics, foils, and light wood fragments) and heavy impurities (like stones, metal fragments, and dense mineral particles) that survive initial pulping stages.

 

Key Functions and Benefits of Hydrapurger

1. Efficient impurity separation: By leveraging a combination of mechanical screening and hydraulic flow, the Hydrapurger captures a broad spectrum of contaminants, reducing the load of foreign matter entering subsequent processing stages.
2. Protection of downstream equipment: Removing impurities at this stage minimizes wear and tear on refiners, refiners screens, cleaners, and other sensitive components, extending equipment life and reducing maintenance costs.
3. Improved pulp quality: Cleaner slurry translates to higher- quality fiber Recovery in later stages, reduced snagging in cleaners, and more uniform sheet formation.
4. Operational stability: The Hydrapurger is designed for continuous, non-stop operation with adjustable parameters to accommodate variations in waste paper input, ensuring stable pulping performance.
5. Versatility with feedstock: Whether processing office recycled paper, mixed paper waste, or mixed grades, the Hydrapurger can adapt to different impurity profiles, making it a flexible solution for recycling facilities.

 

Leizhan represents a critical stage in the waste paper pulping process—efficiently removing both light and heavy impurities to deliver cleaner pulp for downstream processing. By improving pulp quality, protecting equipment, and enhancing overall production stability, the Hydrapurger contributes to more efficient recycling workflows and higher-quality paper products.
