Working Principle:
The pulp enters the low consistency cleaner tangentially at a certain pressure, with a pulp consistency of approximately 0.4–1.2%. Inside the conical body, the pulp rotates at high speed from top to bottom, forming a strong vortex.
Heavier impurities are thrown toward the outer wall of the cone by centrifugal force, then settle downward due to gravity and are discharged through the reject outlet at the bottom.
Lighter, clean accept pulp is driven toward the upper part of the vortex. With the assistance of upward backflushing water at the bottom and dilution water, the clean pulp is collected and discharged from the top outlet and conveyed to the accept pulp pipeline.
The backflushing water at the bottom also helps separate fibers carried in the rejects, further reducing fiber loss.
Main Features and Advantages:
- Efficient removal of fine impurities in pulp: Effectively removes sand, grit, dust, ink, fine debris, hot-melt adhesive, foam, plastic particles, and coarse fiber bundles.
- Reduced fiber loss: The bottom backflushing water design effectively minimizes fiber loss.
- High wear resistance and long service life: The bottom cone is equipped with a ceramic-lined inner surface, offering excellent wear resistance and extended service life.
- High separation efficiency: An elongated cone design and optimized pulp flow structure significantly enhance cleaning performance.
By adopting a multi-stage cleaning configuration, the system can be flexibly designed according to different production line sections, maximizing impurity removal efficiency while minimizing fiber loss.
