Brief: Watch the demo to catch practical tips and quick performance insights on the fluidized-bed roasting system, designed for oxidizing, sulfatizing, and volatilizing roasts. Learn how this equipment enables powdery materials to undergo intense calcination reactions under controlled airflow conditions.
Related Product Features:
  • High production intensity with efficient air-material contact and vigorous relative motion.
  • Enhanced heat and mass transfer due to boiling action, increasing material surface area.
  • Versatile for rapid calcination of fine materials.
  • Simplified operation with easy mechanization and automation capabilities.
  • Available in two furnace types: straight type and upper enlarged furnace.
  • Operates between a stationary fixed bed and an air transport bed.
  • Designed for oxidizing, sulfatizing, and volatilizing roasts.
  • Models range from ZLFT-0.6㎡ to ZLFT-32m² with varying capacities and power requirements.
Domande frequenti:
  • What are the main applications of the fluidized-bed roasting system?
    The system is designed for oxidizing, sulfatizing, and volatilizing roasts, making it ideal for non-ferrous metal concentrates and pyrite roasting in sulfuric acid production.
  • What are the advantages of using an upper enlarged furnace?
    The upper enlarged furnace offers high calcination intensity and superior performance with fine materials, originally developed for pyrite roasting but now adapted for various flotation concentrates.
  • How does the fluidized-bed roasting system enhance heat and mass transfer?
    The boiling action in the system increases material surface area up to 32,800-49,200m² per cubic meter, accelerating reaction rates and improving efficiency.
