Abstract
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.

An agitating feeder 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 comprising:
- an agitating rotor for rotating to agitate the powdery material;
- a housing accommodating the agitating rotor, a first gas flowing rotor, and a second gas flowing rotor;
- a gas passage located outside of the housing;
- and a gas flow device for circulating gas in the housing from the first gas flowing rotor through the gas passage and to the second gas flowing rotor.

- 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,
- wherein the gas flow device includes, in the housing, a first gas flowing rotor for delivering gas upward, a gas passage allowing the gas delivered by the first gas flowing rotor to flow therethrough, and a second gas flowing rotor for delivering downward the gas having flown through the gas passage.
