Abstract
A powdery-material mixing and feeding system is configured to feed a machine configured to execute a post process with mixed-powdery materials obtained by mixing a first powdery material and a second powdery material discharged from powdery-material feeding devices at a required ratio, wherein when a flow rate of the first powdery material discharged from the first powdery-material feeding device departs from a target value by a predetermined amount or more, a 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.
