Blow-Through Rotary Airlock Valves Key Specifications

Rotor Design

Closed-pocket blow-through rotor with 8 heavy-duty blades and oversized air channels for effective purging of dense mineral concentrates and bulk powders.

Housing Material

Ni-hard cast iron housing with optional ceramic tile lining and integrated blow-through air manifold for extreme abrasion resistance in mining operations.

Inlet Size Range

200mm to 500mm heavy-duty flanged inlets with blow-through ports sized for high-pressure conveying of dense mineral ores and industrial bulk materials.

Pressure Rating

Conveying air pressure up to 2.5 bar for long-distance dense-phase pneumatic transport of mineral concentrates and heavy industrial powders.

Temperature Range

Standard operation from -20°C to 120°C, suitable for surface and underground mining, quarrying, and diverse general industrial applications.

Blade Configuration

8-blade closed-pocket rotor with tungsten carbide-tipped replaceable inserts and deep-radiused pockets for complete blow-through purging of abrasive materials.

Industrial Applications

Mineral Concentrate Pipeline Injection
Injects beneficiated mineral concentrates directly into high-pressure pneumatic pipelines feeding processing plants, combining airlock and feeder in one unit.
Calcium Carbonate In-line Conveying
Conveys ground calcium carbonate powder from mill outlets directly into pneumatic transport lines using blow-through air for paper and paint industry supply.
Quarry Fines Recovery Conveying
Feeds captured quarry dust from collection hoppers directly into pneumatic return lines, combining dust extraction and material recovery in a compact system.
