icon
Temperature Range
High-temperature variant rated to 320°C for direct injection of hot DRI kiln dust and sinter fines into pressurized return conveying lines.
icon
Blade Configuration
6-blade closed-pocket rotor with bolt-on hardened alloy steel replaceable tips and deep-radiused pockets for complete material purging during blow-through.

Industrial Applications

Applied in DRI dust injection, blast furnace coal feed, and fume dust re-injection. Blow-through design combines airlock and feeder for compact, high-temperature steel plant installations.
Application 1

DRI Dust Pneumatic Injection

Injects captured DRI kiln dust directly into pressurized return conveying lines using blow-through air, eliminating separate screw feeders in the dust recovery circuit.
Application 2

Blast Furnace Injection Coal Feed

Meters and injects pulverized coal directly into blast furnace tuyere injection lines, providing combined airlock and feeder functions in a compact installation.
Application 3

Steel Mill Fume Dust Re-injection

Feeds collected fume dust from bag filter hoppers into pressurized conveying lines for recycling back into EAF or BOF steelmaking vessels.
