At the heart of Leizhan’s Hydrapurger is our proprietary patented rotor and separation chamber design. Unlike conventional models that use a one-size-fits-all blade configuration, our custom-engineered rotor features variable-pitch, wear-resistant stainless steel blades that generate a powerful, controlled centrifugal vortex. This vortex pulls heavy contaminants downward to the concentrator discharge chamber while gently lifting light, good pulp fibers upward to the accept outlet. The precision-shaped inner chamber is lined with abrasion-resistant alloy to withstand constant impact from grit and metal fragments, extending the service life of your machine by up to 40% compared to industry standards.

We tailor the rotor speed, chamber volume, and discharge geometry to match your specific pulp input—whether you’re processing low-grade mixed post-consumer waste, high-grade deinked office pulp, or even virgin pulp with naturally occurring heavy debris. The result? Up to 99% removal of all heavy contaminants larger than 0.5mm, including plastic, grit, metal, rubber, and hot-melt adhesives—far higher than the 90-95% average of older hydrapurger models. That means far fewer contaminants reach your downstream screens, refiners, and paper machines, reducing equipment wear and eliminating costly defects in your finished product.

Our impurity separator has received unanimous praise from paper mills across multiple countries; we invite you to learn more about our pulping equipment. You can get stronger, higher-quality paper that meets the strictest grade specifications, without sacrificing yield.
