FAQ
Which plate is best for sticky, high‑moisture raw coal (50-150mm)?
Flip‑Flow Screen Panel with PU surface. Its tension‑relaxation movement creates rubbing force that breaks mud clumps, achieving 85–95% sieving rate even at >20% moisture.
How does the wavy anti‑clogging plate prevent blinding?
Wave peaks (5-10mm) force material to bounce, and trapezoidal holes (wide top/narrow bottom) release lodged particles. Anti‑clogging rate >90% with 75-85% sieving rate.
How does it prevent particle breakage during screening?
The outer woven mesh has “rounded-edge” square holes, and the elasticity of the mesh buffers impact. The inner steel mesh provides rigid support, keeping breakage rate ≤3% even for friable materials like limestone, while maintaining 90% sieving rate.
What moisture level can the flip-flow screen handle effectively?
It handles materials with moisture >20% (e.g., lignite, muddy iron ore). The 5-8mm amplitude, 50-60Hz asynchronous vibration creates tension-relaxation movement, generating rubbing force that breaks mud clumps, achieving 85-95% sieving rate — 1.5× ordinary plates.
Which hole shape is better for my material — round or square?
Round holes (50-100mm) suit spherical particles like pebbles; square holes (100-200mm) fit blocky materials like limestone. Both feature smooth walls to reduce resistance, and stainless steel options resist high salt-fog environments.
How does it achieve ≤5% clogging for materials with stone powder?
The parallel elastic steel rods micro-bend under vibration, shaking off stuck powder clumps. Rod spacing is adjustable for different cut sizes, and quenched rods offer 3× wear life of ordinary steel — ideal for copper ore, manufactured sand, and phosphate rock.
