Abstract
A powdery-material feeding device is configured to feed a powdery material to a compression-molding machine configured to obtain a molded product by filling a die bore with the powdery material and to compress the powdery material with punches. The powdery-material feeding device includes a detector configured to detect a biologically-originated foreign matter mixedly contained in the powdery material to be fed to the compression-molding machine, and a controller configured to control to remove the powdery material mixedly containing the biologically-originated foreign matter detected by the detector to avoid feeding of the powdery material mixedly containing the biologically-originated foreign matter to the compression-molding machine, or to control to stop the feeding of the powdery material to the compression-molding machine.
