OCC Paper Recycling and Pulping System

A poorly designed OCC recycling system doesn’t just waste fiber. It quietly erodes your profit through excessive power draw, high reject rates, frequent screen clogging, and unnecessary refining load downstream. I’ve seen mills running beautiful paper machines at 700 meters per minute, only to lose six hours a week clearing junk from their pulping line. That’s not a paper machine problem. That’s a pulping philosophy problem. At Leizhan, we’ve spent the last two decades treating the pulping room as the real profit center of a paper mill. Our OCC paper recycling and pulping systems are not collections of standalone machines bolted together. They are integrated process lines, engineered around a single idea: recover the maximum amount of clean, usable fiber at the lowest possible energy cost.

Leizhan OCC Pulping Line: What Actually Happens Inside

The D-Type Hydrapulper is where it starts. Our vortex tub geometry hits 14–18% consistency with faster defibering and lower specific energy. The alloy rotor runs for years without rebalance. You process more tons per kilowatt.

Screening is where OCC lines usually die. Leizhan configures pressure screens with slotted baskets and tailing screens matched to your actual furnish. We design for the reality of Asian, Middle Eastern, and African OCC—higher ash, more adhesives, tougher trash. A system built for clean Swedish kraft will choke on your bales. We know, because we’ve retrofitted enough competitor lines to prove it.

Three-stage low-density cleaner cascades pull out sand and grit with fiber loss below 0.4%. For mills facing printability demands, our Heat Dispersion System pulverizes micro-stickies and wax into particles too small to spot your finished sheet.
