Positive pressure airlock ZGF meters the material flow rate into a positive-pressure conveying pipe line which is then transported away by air. This airlock type is widely used as a feeder device in a positive-pressure conveying system for flour, bran, starch, grain, feed, sugar, chemical, plastic granular materials. There is an axial discharging groove beneath the airlock casing which serves for the conveying operation.
