1. A powdery-material mixing and feeding system comprising:
a first powdery-material feeding device configured to reserve and discharge a first powdery material; and
a second powdery-material feeding device configured to reserve and discharge a second powdery material, the powdery-material mixing and feeding system being configured to feed a machine configured to execute processing of a post process with mixed-powdery materials obtained by mixing the first powdery material and the second powdery material respectively discharged from the first and second powdery-material feeding devices at a required ratio, in which a controller is included for controlling a flow rate of the first powdery material discharged from the first powdery-material feeding device and a flow rate of the second powdery material discharged from the second powdery-material feeding device to converge to respective target values thereof,
wherein when the flow rate of the first powdery material discharged from the first powdery-material feeding device departs from the target value thereof by a predetermined amount or more, the controller increases or decreases the flow rate of the second powdery material discharged from the second powdery-material feeding device such that the ratio of the first powdery material to the second powdery material contained in the mixed-powdery materials is kept within a desired range.
