What Is Rotary Airlock (Star Discharger)? Structure, Working Principle & Core Advantages
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.
1. Main Structure of Star Discharger
- Housing: Cast iron/stainless steel shell to protect inner components
- Star-vane rotor: Multi-blade rotating part for quantitative feeding
- Multi-layer sealing system: Stop air leakage and dust backflow
- Drive unit: Ordinary/burst-proof/variable frequency motor as power source
2. Working Principle
- Bulk material(powder, granule, small lump) falls into rotor blade cavity from upper inlet by gravity
- Motor drives rotor to rotate, material moves from top to bottom outlet
- Tight clearance between rotor and shell isolates air pressure, realizing both discharging and air locking, avoiding gas backflow
3. Core Product Advantages of Fuzhisen Rotary Airlock
- Precise flow control: Adjust rotating speed to change feeding volume flexibly
- Excellent airtightness: Double sealing design prevents material backflow and dust leakage
- Wide compatibility: Fits powder, granular, sticky & abrasive materials
- Low maintenance: Compact layout, easy disassembly & daily cleaning, cut after-sales cost
- Long service life: High-strength raw material & precise processing, stable continuous operation
