Star unloader 星型卸料器

Star unloader, also known as rotary airlock valve, is a core supporting accessory of dedusting equipment. It drives the rotor impeller to rotate uniformly via a speed reduction motor, continuously discharges dust materials stored in the ash hopper, and maintains airtight isolation between the dust removal box and ash outlet to prevent air leakage. Widely matched with bag dust collectors, cyclone separators, bucket elevators and other conveying & dust removal equipment, suitable for dust ash, granular raw materials in metallurgy, chemical industry, building materials, grain processing, power plant and foundry industries.

Product Classification:

1.Ordinary star unloader: for normal temperature, non-corrosive dry dust

2.High temperature resistant star unloader: special high temperature resistant rotor & housing, working temperature ≤300℃

3.Explosion-proof star unloader: explosion-proof motor and sealing structure, for flammable and combustible powder materials

4.Square/round flange star unloader: different inlet and outlet shapes to match various dust hopper sizes

Professional Advantages:

1.Good air tightness: multi-layer labyrinth sealing structure, effectively reduce air leakage rate of dust removal system

2.Stable operation: integrated reducer motor, low vibration, low noise, long service life

3.Customizable structure: cast iron / stainless steel body optional, rotor anti-blocking design for sticky materials

4.Easy maintenance: quick disassembly structure for convenient cleaning and replacement of wearing parts
