Drop-Through Rotary Airlock Valves for Cement Plants

UGES drop-through rotary airlock valves deliver precise volumetric feeding and reliable air sealing in high-dust cement processing lines. Engineered with abrasion-resistant Ni-hard housings and adjustable-tip rotor blades, these valves maintain consistent clinker and raw meal flow under pressures up to 1.5 bar.

Trusted by the largest brands

Drop-Through Rotary Airlock Valves Key Specifications

Ni-hard cast iron housings, 8-blade adjustable-tip rotors, and 200mm to 600mm inlets. Rated for pressures up to 1.5 bar and temperatures up to 300°C for reliable air sealing in abrasive cement environments.

Rotor Design

Open-end drop-through rotor with 8 precision-machined blades for gravity-fed material discharge, ensuring minimal product retention and continuous flow of cement raw meal and clinker.

Housing Material

Ni-hard cast iron housing rated for extreme abrasion resistance, withstanding the erosive action of calcium carbonate and pulverized clinker in cement processing.

Inlet Size Range

Available in 200mm to 600mm square and round inlet flanges, sized to match cement plant pneumatic conveying line diameters and hopper discharge outlets.

Pressure Rating

Differential pressure sealing up to 1.5 bar with close-tolerance rotor-to-housing clearances, preventing air leakage in pressurized cement conveying systems.

Temperature Range

Standard operation from -20°C to 120°C with high-temperature variant available up to 300°C for post-kiln clinker handling and hot raw meal transfer.

Blade Configuration

8-blade adjustable-tip rotor with replaceable alloy steel inserts, allowing field adjustment of rotor-to-housing clearance to compensate for wear.

Industrial Applications

Deployed in raw mill cyclone discharge, cement silo extraction, and bag filter dust re-injection. Open-end drop-through design enables gravity-fed flow with minimal retention for continuous cement operations.

Application 1

Raw Mill Cyclone Discharge

Provides consistent airlock sealing at raw mill cyclone separators, metering fine limestone and clay powder into the conveying line while preventing back-pressure loss.

Application 2

Cement Silo Extraction

Feeds finished cement from storage silos into pneumatic conveying lines at controlled volumetric rates, preventing flooding and maintaining steady packing line throughput.

Application 3

Bag Filter Dust Re-injection

Re-injects captured kiln dust from bag filter hoppers back into the process, ensuring zero-waste operation while maintaining negative pressure in the dust collection system.
