Self-Cleaning Piano Wire Screen
DUNPAI manufactures its piano wire screens with quality high-manganese steel and stainless steel, which ensure far fewer declines in screening capacity and efficiency over a long period.
With regard to service life, our self-cleaning wire screens have thick wires and the screen surface features uniform tensions, which avoid damages to screens and ensure a long service life.
Our piano wire screens can be applied in mining industry to solve screens clogging problems, since they have no cross wires, which ensure maximum Opening Areas, allowing for the effective screening of sands, pebbles, soils, topsoil and fertilizers. The opening of our wire screens ranges from 1/16 inch – 1 inch.
Features- Anti-clogging and anti-pegging;
- Fine screening;
- Quality materials;
- Increased service life
