Structure, Working Principle & Core Advantages"},"content":{"rendered":"\n

Rotary airlock, also named star discharger or air lock feeder, is core equipment for bulk material conveying & dust removal system. Fuzhisen, based in Changzhou China, specializes in designing and manufacturing standard & customized rotary airlocks for global clients from chemical, food, grain, construction industries.<\/p>\n\n\n\n

1. Main Structure of Star Discharger<\/h3>\n\n\n\n
\n
\n
    \n
  • Housing: Cast iron\/stainless steel shell to protect inner components<\/li>\n\n\n\n
  • Star-vane rotor: Multi-blade rotating part for quantitative feeding<\/li>\n<\/ul>\n<\/div>\n\n\n\n
    \n
      \n
    • Multi-layer sealing system: Stop air leakage and dust backflow<\/li>\n\n\n\n
    • Drive unit: Ordinary\/burst-proof\/variable frequency motor as power source<\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n\n\n
      \n
      \n

      2. Working Principle<\/h2>\n\n\n\n
        \n
      1. Bulk material(powder, granule, small lump) falls into rotor blade cavity from upper inlet by gravity<\/li>\n\n\n\n
      2. Motor drives rotor to rotate, material moves from top to bottom outlet<\/li>\n\n\n\n
      3. Tight clearance between rotor and shell isolates air pressure, realizing both discharging and air locking, avoiding gas backflow<\/li>\n<\/ol>\n\n\n\n

        3. Core Product Advantages of Fuzhisen Rotary Airlock<\/h2>\n\n\n\n
          \n
        1. Precise flow control: Adjust rotating speed to change feeding volume flexibly<\/li>\n\n\n\n
        2. Excellent airtightness: Double sealing design prevents material backflow and dust leakage<\/li>\n\n\n\n
        3. Wide compatibility: Fits powder, granular, sticky & abrasive materials<\/li>\n\n\n\n
        4. Low maintenance: Compact layout, easy disassembly & daily cleaning, cut after-sales cost<\/li>\n\n\n\n
        5. Long service life: High-strength raw material & precise processing, stable continuous operation<\/li>\n<\/ol>\n<\/div>\n\n\n\n
