Drop-Through Rotary Airlock Valves Key Specifications

Rotor Design

Open-end drop-through rotor with 8 heavy-duty blades and increased shaft diameter for handling high bulk-density mineral ores, crushed aggregates, and mine tailings.

Housing Material

Ni-hard cast iron housing with optional ceramic tile lining for extreme abrasion resistance in handling quartz-bearing minerals and mineral sand concentrates.

Inlet Size Range

200mm to 600mm heavy-duty flanged inlets for integration with vibrating screen underflows, crusher product hoppers, and mineral processing cyclone discharges.

Pressure Rating

Differential pressure sealing up to 2.5 bar for high-pressure pneumatic conveying of dense mineral concentrates and mine backfill materials.

Temperature Range

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

Blade Configuration

8-blade rotor with bolt-on tungsten carbide-tipped replaceable inserts, providing maximum wear life in highly abrasive mining and quarrying applications.

Industrial Applications

Ore Concentrate Conveying
Meters beneficiated ore concentrates from thickener underflow hoppers into pneumatic conveying systems feeding smelters, maintaining precise feed rate and pressure isolation.
Quarry Dust Collection Discharge
Evacuates collected stone dust from crusher and screen house bag filters, sealing the dust extraction system while metering captured fines into return conveyors.
General Bulk Material Handling
Provides versatile airlock and metering for diverse bulk solids including calcium carbonate, talc, and industrial minerals in general processing plants.
