Airlocks, also known as rotary airlocks, rotary valves, or rotary feeders are used to discharge bulk solids materials such as powders, granules, and pellets from hoppers, bins, receivers, and cyclones into a pneumatic conveying system.
Airlocks serve a number of purposes that include acting as a sealing device against loss of air while maintaining a flow of bulk materials between components in a pneumatic conveying system, used as a volumetric feeder for metering materials from bins or silos into a conveying system, and as a gravity discharger for cyclone dust collectors or filters. Schenck Process offers a wide range of airlocks for industrial, sanitary and high process rate applications.
