Apparatus for automatically determining bulk specific gravity of powdery product
 An apparatus which permits continuous automatic determination of the bulk specific gravity of a powdery sample and highly precise measurement thereof. The apparatus comprises a robot 3 transporting a container 2 filled with a powdery sample; a funnel 4 provided with a damper, which receives the powdery sample discharged from the container 2; a damper-driving unit 5a for pulling out and pushing the damper 5; a sample sensor 7 for detecting the powdery sample dropped through the funnel 4 provided with a damper; a constant volume receiver 6 for receiving dropped through the funnel 4 provided with a damper; a scraping bar 8 for sliding the upper face of the constant volume receiver 6; a scraping bar-driving unit 8a for reciprocating the scraping bar 8; a constant volume receiver-conveying robot 21 transporting the constant volume receiver 6; an electronic balance 22 which determines the weight the powdery sample in the constant volume receiver 6; and a cleaner 23 for aspirating the weighed powdery sample.
