How to Handle Blockages in Pulping Line

The root cause of blockages in paper making lines often originates in the pulping stage. Entangled materials such as ropes and long strips of plastic in waste paper are common causes of blockages in pulping equipment. Leizhan’s drum pulper with a rope guide function utilizes axial slots on the feed plate in the screening zone to create a dedicated “channel” for these entangled materials, allowing them to be smoothly discharged from the slag outlet. This effectively reduces downtime caused by cleaning entangled materials and significantly improves production efficiency.

In the screening section, light impurities such as foam and plastic flakes easily clog the screen of the pressure screen, affecting screening efficiency. Leizhan’s patented technology for “Pressure Screen Rotor to Prevent Clogging by Light Impurities” adds a water seal ring structure to the transmission support and rotor, injecting sealing water to form a “water barrier.” This effectively prevents light impurities such as foam and plastic from entering the rotor, solving the clogging problem caused by light impurities at its source.
