High-Efficiency Iron Ore Dewatering Solutions
Lower cake moisture to under 9%, prevent filter cloth blinding, and maximize throughput with specialized Vacuum Negative Pressure Disc Filters.
Key Challenges in Iron Ore Concentrate Dewatering
- High Cake Moisture Content: Ultrafine iron ore concentrates often retain excessive water, increasing transport costs and failing smelter acceptance thresholds (<10%).
- Filter Cloth Blinding & Abrasion: Heavy, abrasive iron slurries accelerate wear on filter sectors and clog fabric pores, leading to frequent downtime.
- Unstable Vacuum Pressure: Inefficient air/filtrate discharge causes vacuum drops, reducing filtration speed and cake formation thickness.
Vacuum Negative Pressure Disc Filter Solution
Engineered specifically for heavy iron ore slurry
Our continuous vacuum disc filter utilizes enhanced vacuum negative pressure technology to ensure fast cake formation, optimal moisture extraction, and instant cake discharge.
- High Vacuum Duty Cycle: Maintains optimized negative pressure ($>0.06$ MPa) across all sector sectors.
- Anti-Abrasion Sector Design: Reinforced disc sectors resist abrasive iron concentrates while maximizing filtration surface area.
- Efficient Snap-Blow Cake Release: Controlled compressed air blowback ensures clean cake detachment without damaging the filter cloth.
