DOSING DEVICE WITH PNEUMATIC DISCHARGE FOR FLOWABLE SOLIDS

摘要

In a feeding device of the rotary valve type with pneumatic discharge of the pockets of a rotor in the direction parallel to a portion of the rotor hub of the rotor the shaft has a conical shape such that a conveying duct for the gas/solid mixture is formed by one pocket of the rotor, the wall of the rotor casing and the rotor hub, which duct diminishes in diameter from the gas inlet opening to the outlet opening for the gas/solid mixture, the said opening extending over two pockets of the rotor.
