Agitating feeder and compression molding machine

摘要

An agitating feeder is provided in a compression molding machine that includes at least one die having a die bore, an upper punch and a lower punch retained respectively above and below the die so as to be vertically slidable, and a compression mechanism for compressing and molding a powdery material filled in the die bore by the upper punch and the lower punch. The agitating feeder includes an agitating rotor for rotating to agitate the powdery material, a housing accommodating the agitating rotor, and a gas flow device for flowing gas in the housing.
