Drop-Through Rotary Airlock Valves Key Specifications

Rotor Design

Open-end drop-through rotor with 6 heavy-duty blades and increased pocket depth for high bulk-density metallurgical materials like iron ore fines and sinter feed.

Housing Material

Ni-hard cast iron housing with flame-hardened bore for maximum abrasion resistance against iron ore pellets, DRI fines, and flux powders.

Inlet Size Range

250mm to 600mm heavy-duty flanged inlets for integration with DRI kiln discharge hoppers and blast furnace stock house conveying systems.

Pressure Rating

Differential pressure sealing up to 2.0 bar for high-pressure pneumatic conveying of dense metallurgical materials in steel plant dust recovery circuits.

Temperature Range

High-temperature variant rated to 350°C for direct discharge of hot DRI kiln dust, sinter cooler fines, and post-reduction iron material handling.

Blade Configuration

6-blade heavy-duty rotor with bolt-on replaceable hardened alloy steel tips, providing extended service intervals in aggressive metallurgical dust environments.

Industrial Applications

DRI Kiln Dust Collection Discharge
Feeds captured kiln dust from DRI rotary kiln bag filters and cyclones into return conveyors, maintaining process vacuum while ensuring zero particulate emission.
Blast Furnace Stock House Feed
Meters iron ore fines, coke breeze, and limestone flux from weigh hoppers into pneumatic conveying lines feeding the blast furnace charging system.
Sinter Plant De-dusting Discharge
Evacuates collected sinter dust from ESP and bag filter hoppers in the sinter strand off-gas cleaning system, sealing high-volume dust collection circuits.
