Powdery material mixing degree measurement device, powdery material mixing and feeding system, and compression-molding machine including the same

A powdery material mixing degree measurement device configured to measure a mixing degree of mixed powdery materials including at least two types of powdery materials, the device comprising:

• a case including a rotor rotating in a radial direction of the case;
• a discharger including an opening in the case and configured to discharge the mixed powdery materials to a filler configured to fill, with the powdery materials disposed inside of the case, a die bore of a compression-molding machine configured to cause punches to compress the mixed powdery materials in the die bore to mold a molded product,
• the rotor comprising a plurality of movable portions configured to rotate in the radial direction of the case to move the mixed powdery materials disposed inside of the case to the opening of the discharger;
• a feeding unit configured to feed the mixed powdery materials into the case;
• and
• a first sensor disposed in the case and a. second sensor disposed in the feeding unit and configured to measure a mixing degree of the mixed powdery materials in the feeding unit.
