  • Publication number: 20160293329
    Abstract: A powder-filling system capable of filling a container with powder at an approximately uniform filling density has: a hopper having an opening removably and hermetically closably attached to the container, the hopper communicating with the container at the opening for supplying powder to a container; a powder supplier for supplying powder to the hopper; a gas supplier for repeatedly supplying compressed gas in a pulsed form to the hopper, with the hopper hermetically closably attached to the container; and a sieve member provided at the opening and having a smaller openings in a region near a side wall of the hopper than in its central region. The smaller openings in the region near the side wall of the hopper where the powder more easily falls from the hopper into the container impedes the fall of the powder in that region and improves the overall uniformity in the filling density.
