Rotary feeders, also known as rotary airlock valves or rotary vane feeders, are essential equipment in bulk material handling systems. They accurately meter powders, granules, and pellets while maintaining an airtight seal. Used with hoppers, bins, cyclones, and dust collectors, they ensure smooth, reliable transfer in pneumatic conveying and gravity discharge applications.

We manufacture both stainless steel and carbon steel rotary feeders to suit various industrial applications. Stainless steel models meet food-grade and pharmaceutical standards, while carbon steel units offer excellent durability for cement, mining, and chemical processing. All models are available at competitive factory prices with short lead times.

A rotary feeder consists of a housing, a rotor with vanes, and a drive unit. As the rotor rotates, pockets fill with material at the inlet and discharge at the outlet. The small clearance between rotor and housing minimizes air leakage, preserving pressure differences in pneumatic systems and preventing product backflow.

Key features include compact structure, low power consumption, stable feeding, and low noise. The rotor is precision-machined for high volumetric efficiency and consistent throughput. Interchangeable shaft seals and bearing housings simplify installation and maintenance. Wear-resistant options expand service life in abrasive applications.

Typical applications include conveying and metering of powders, granules, flakes, and pellets in pneumatic conveying systems, dust collectors, mixers, reactors, and storage silos. Rotary feeders are trusted in industries such as plastics, chemicals, food processing, pharmaceuticals, power generation, and building materials.

Selecting the right rotary feeder requires consideration of material bulk density, flowability, pressure differential, temperature, and required capacity. Our engineering team assists with accurate calculations and recommends the ideal rotor type, housing material, and sealing design for your specific process.

We offer customized rotary feeders with various rotor designs, flange standards, shaft seal arrangements, and discharge configurations. Options include blow-through, drop-through, and side-entry types. For abrasive or corrosive materials, ceramic liners, hard chromium plating, and stainless steel construction are available.

Every rotary feeder is manufactured under strict quality control. Before delivery, it undergoes run testing, leakage inspection, and dimensional verification. Test reports and material certificates are provided to ensure full traceability. This guarantees reliable performance and long service life in demanding environments.

Maintenance is simple and convenient. Regular lubrication, inspection of rotor tips and shaft seals, and timely replacement of wear parts keep the feeder operating efficiently. Our after-sales support includes spare parts supply, technical guidance, and prompt response to customer inquiries.

Available sizes range from small laboratory units to large industrial feeders, with capacities up to several hundred cubic meters per hour. Rotor speeds and motor power are selected according to material characteristics and feeding requirements. Customized flanges, discharge options, and explosion-proof motors are also available.
