ROTARY FEEDER

The prime function of a rotary airlock valve is to regulate the flow from one chamber to another while maintaining a good airlock condition. Basically the valve is designed with a paddle wheel which is shaft-mounted and driven by a motor. The rotary valve is similar to a revolving door: the paddles or blades create a triangular pocket between blades and the circular housing that it is rotating in and form an airtight seal with the housing; the motor slowly moves the blades to allow the solids to discharge from the hopper. Packing glands of generous proportions seal against air or gas leakage into or out of the feeder. Self lubricating packing designed to sustain operating temperature.
