An airlock rotary valve is a mechanical conveying device that allows to control a bulk solids flow (powder, pellets, granules...). Such airlock feeders (also called rotary valve feeder or star valve) are often used prior to a pneumatic transport system.
INTRODUCTION. The prime function of a rotary airlock is to regulate the flow from one chamber to another while maintaining a good airlock condition. The product is mainly in dry powder or granular form.
What is a Rotary Valve? It is a compact mechanical device for continuously discharging bulk powders or granules under gravity flow. By definition it is the simplest of machines having only one moving part (ignoring the drive); a multi-vane Rotor revolving with close
