Blow-Through Rotary Airlock Valves for Cement Plants

UGES blow-through rotary airlock valves enable direct in-line pneumatic conveying of cement raw meal, clinker fines, and finished cement powder. With closed-pocket rotors that allow conveying air to pass directly through the valve body, they eliminate the need for separate feeding devices in cement plant material transfer.

Trusted by the largest brands

Blow-Through Rotary Airlock Valves Key Specifications

Ni-hard housings with blow-through ports, 8-blade closed-pocket rotors, and 200mm to 500mm inlets. Rated for 1.5 bar conveying pressure and up to 280°C for in-line cement pneumatic conveying.

Rotor Design

Closed-pocket blow-through rotor with 8 blades featuring internal air passages that allow pressurized conveying air to sweep material directly from pockets into the downstream line.

Housing Material

Ni-hard cast iron housing with blow-through air inlet and outlet ports, engineered for abrasion resistance against calcium carbonate and clinker fines.

Inlet Size Range

200mm to 500mm inlet flanges with integrated blow-through air nozzles, designed for direct connection to cement plant pneumatic conveying pipelines.

Pressure Rating

Operates with conveying air pressures up to 1.5 bar, with rotor pocket sealing that minimizes air bypass and maintains conveying efficiency in cement lines.

Temperature Range

Standard operation to 120°C with high-temperature variant to 280°C for hot clinker fines and preheater discharge applications in cement kilns.

Blade Configuration

8-blade closed-pocket rotor with adjustable hardened steel tips and beveled pocket edges for clean material release during the blow-through cycle.

Industrial Applications

Applied in raw meal conveying, finished cement transfer, and kiln dust recovery. Closed-pocket blow-through design combines airlock and feeder into one unit for compact cement plant layouts.

Application 1

Cement Raw Meal Conveying

Feeds raw meal directly from preheater cyclones into pneumatic conveying lines using blow-through air, eliminating separate rotary feeders and reducing equipment footprint.

Application 2

Finished Cement Transfer

Conveys finished cement from grinding mill outlets into storage silos via integrated blow-through design, maintaining product quality with minimal degradation.

Application 3

Kiln Dust Recovery Line

Feeds captured cement kiln dust from filter hoppers directly into pressurized return lines, combining airlock and feeder functions in a single compact unit.
