Unlike high-consistency pulpers that use rotors for violent tearing, the Drum Pulper operates on a elegantly simple principle. The raw material is fed into a large, rotating drum partially filled with process water. As the drum turns, the raw material is gently lifted by internal baffles before tumbling back down through the water. This cascading action, combined with the friction between fibers, facilitates a gradual and thorough disintegration.

 

Available in a wide range of diameters and lengths, Leizhan offers solutions for small, medium, and mega-scale production lines. They are highly effective for various feedstocks, from standard recycled cartons to more challenging mixed waste streams. Leizhan provides complete solutions, often integrating the Drum Pulper with ragging systems, junk traps, and high-density cleaners. This ensures a smooth, continuous flow and maximizes the quality of the accepted pulp. Modern Leizhan units can be equipped with advanced PLC controls, allowing for automated operation, speed adjustment based on load, and seamless integration into the mill’s DCS for optimal process management.

 

For any operation looking to upgrade its fiberline or design a new one, Leizhan’s expertise in Drum Pulper technology represents a proven path toward a more efficient, sustainable, and competitive future in pulp and paper manufacturing.
