vacuum filter
1. Structure
2. Applications
Typical applications for the horizontal vacuum belt filter include:
Dewatering | Washing |
Coal fines | Gold/silver recovery in cyanide process |
Rutile/zircon and titanium sands | Washing of phosphate rock |
Iron ore fines (both hematite and magnetite) | Nickel/cobalt and manganese salts |
Pyrites | Uranium for SX recovery |
Nickel | Potash/soda ash and lithium salts |
Zinc | Acid-leached copper and cobalt |
Lead | Recovery of alumina from sintered mud |
Copper | Vanadium leached from magnetite |
Phosphate rock | Hemihydrate and di-hydrate calcium sulfate from phosphoric acids |
3. Technology
DU series Rubber Belt Filter is the high automatic new-type machine. It adopts setting vacuum chamber and the rubber belt moves on the chamber. It has realized the continuous filtration, cake cleaning, residue unloading and cloth cleaning and regeneration etc used in the fields of solid-liquid separation of the chemical industry, coal chemical, metallurgy, mines, flue gas desulfurization, food industry etc.
Features:
1. Modularized design is for easy installation and transportation.
2. High auto degrees: Consecutive auto feeding, filtering, washing, dewatering, discharging, cloth cleaning improves production efficiency.
3. Fast filter speed: large particles will settle at the lower layer while small particles upper layer when material goes through sedimentation area. Reasonable structure of filter cake ensures low resistance of liquid for fast filter of thin layer.
4. Convenient filter technology: cake thickness, water vol., counter current decantation stages, vacuum degree, filter speed can be adjusted for optimistic effect.
5. Fine decantation effect: even and thorough multi-stage advection or counter current decantation makes collection and reuse of mother liquor and washing liquor separately.
