Rotary Feeders, Rotary Valves, and Rotary Airlocks:Understanding the Differences
Differences Between Rotary Feeders, Valves, and Airlocks Rotary feeders primarily meter/transfer bulk solids (e.g., grains, powders) at controlled rates, prioritizing consistent material flow over airtightness. Rotary valves focus on on/off flow control of solids or gases; they regulate passage, not just feed, and may have basic sealing but not for high-pressure differential. Rotary airlocks are specialized for maintaining air/gas tightness (e.g., in pneumatic systems) while feeding solids. They prevent pressure loss between system sections, with tight clearances for sealing—their key function, unlike feeders/valves.

What Is A Rotary Feeder: A Key Device for Conveying Bulk Materials
The rotary feeder, also known as a star valve or airlock, is a crucial device for conveying bulk materials. It features a rotating impeller within a sealed housing, which evenly distributes and feeds materials from an upper hopper to a lower discharge point. Available in various types like electric, high-temperature, and wear-resistant models, it ensures airtightness and continuous, uniform feeding. Widely used in industries such as mining, chemical, and food processing, it prevents material leakage and maintains system efficiency.
