ABSTRACT:
A powder constant-volume feeder includes a canister having on the inner surface thereof a fin for transferring powder upwards and is inclined to form a return portion for the powder which has been transferred by the fin. A bucket wheel has a plurality of buckets for continuously transferring the powder from the interior of the return portion to a powder hopper. The powder hopper receives the powder from the interior of the buckets of the bucket wheel. A constant volume of powder can thus be fed continously at a constant bulk density.
