PROBLEM TO BE SOLVED: To solve a problem wherein a constitution taking into consideration to surely prevent peripheral scattering in addition to ignition and explosion-proofing of granular powder and capable of completely separating material, is conventionally nonexistent, in a fixed volume feeder device of the granular powder.SOLUTION: A carrying system of a fixed volume feeder of granular powder constituted of a supply hopper of the granular powder, a driving part arranged under the hopper, a supply board installed on a rotary shaft interlocked with the driving part and a discharge chute formed under the outer end of the supply board, is stored in a sealed housing. The inside of the housing is put in a vacuum state or a state of filling inert gas, and an electric system including a motor for operating the driving part, is arranged outside the housing, and a motor shaft and a driving shaft of the driving part are connected by sandwiching the housing by magnetic coupling. |
