Offset Rotary Airlock Valves for Steel & Sponge Iron Plants

UGES offset rotary airlock valves deliver reduced-wear, low-degradation material handling for iron ore pellets, DRI product, and metallurgical materials in steel and sponge iron plants. The offset rotor geometry minimizes the crushing zone to protect fragile DRI pellets and reduce rotor wear from abrasive ores.

Offset Rotary Airlock Valves Key Specifications

Rotor Design

Offset-mounted rotor with 6 heavy-duty blades and asymmetric clearance, reducing the nip point to prevent crushing of DRI pellets and iron ore granules.

Housing Material

Ni-hard cast iron housing with flame-hardened offset bore geometry, providing extreme abrasion resistance with reduced localized wear at the rotor-housing interface.

Inlet Size Range

250mm to 500mm inlet flanges with enlarged offset entry zone sized for gentle handling of DRI pellets and iron ore materials up to 25mm particle size.

Pressure Rating

Differential pressure sealing up to 2.0 bar with offset geometry maintaining seal integrity while reducing material trapping and crushing at the rotor interface.

Temperature Range

High-temperature variant rated to 350°C for direct handling of hot DRI product and sinter material requiring gentle transfer to preserve pellet integrity.

Blade Configuration

6-blade heavy-duty offset rotor with bolt-on replaceable hardened tips and enlarged pocket geometry for gentle material pickup and reduced attrition discharge.

Industrial Applications

DRI Pellet Gentle Transfer
Transfers hot DRI pellets from reduction furnace discharge to storage with minimal pellet breakage, preserving pellet strength for electric arc furnace charging.
Iron Ore Pellet Metering
Meters iron ore pellets from screening stations into conveying lines without crushing, maintaining pellet size distribution required for blast furnace burden quality.
Sinter Product Low-Degradation Feed
Feeds sinter product from cooler discharge with reduced breakage, preserving the sinter lump size distribution critical for blast furnace permeability.
