Product Introduction
The Low Density Cleaner (LD Cleaner) is a critical component in the approach flow system of paper machines. Utilizing advanced centrifugal separation technology, it removes heavy contaminants (sand, grit, metal bits, glass, and shives) from the pulp stock.
By ensuring the highest level of pulp cleanliness, our LD Cleaners protect downstream equipment like headboxes and forming wires, significantly reducing the risk of paper breaks and extending the life of your machinery.
Key Features & Benefits
-
-
Boosts Cleaning Efficiency: The optimized hydrodynamic shape generates powerful centrifugal forces, effectively separating even the smallest heavy particles from the fiber.
-
Resists Extreme Wear: We craft the lower cone from high-tech ceramics (Alumina/Silicon Carbide) or Polyurethane, which extends the equipment’s lifespan by 3–5 times compared to standard stainless steel components.
-
Minimizes Fiber Loss: Our system maintains precise control over the reject rate to remove heavy contaminants while retaining valuable long fibers within the production cycle.
-
Prevents Clogging: The smooth inner surfaces and specialized nozzle geometry eliminate blockages, ensuring seamless, 24/7 continuous operation.
-
Scales with Your Production: You can easily configure the units into multi-stage, multi-segment systems (Primary, Secondary, and Tertiary) to match your specific capacity requirements.

Frequently Asked Questions (FAQ)
Q: What is the main difference between an HD Cleaner and an LD Cleaner?
A: High Density (HD) Cleaners operate at 2-5% consistency to remove large debris early in the process. Low Density (LD) Cleaners work at 0.4-1.2% consistency to remove fine, heavy contaminants right before the paper machine.
Q: How do I choose between Ceramic and Polyurethane cones?
A: Ceramic cones are best for highly abrasive stocks (e.g., recycled waste paper with high sand content) as they offer maximum hardness. Polyurethane is more cost-effective and impact-resistant for cleaner virgin pulp applications.
