Abstract: A metering feeder is provided with the following: an annular transport space formed by an outer cylinder, an inner cylinder, and a bottom plate; a central rotating blade provided on a rotating shaft in the center of the bottom plate; an outer rotating ring connected to the tip of the central rotating blade; a plurality of outer rotating blades provided on the outer rotating ring so as to point inwards; and a rotating disc in which a powder/granular-material discharge groove is formed, the top surface of said rotating disc lying in the same plane as the top surface of the bottom plate. The outer rotating blades scrape the powder/granular material in the annular-transport space into the powder/granular-material discharge groove, which transports said powder/granular material outside the outer cylinder. This metering feeder is further provided with a vertically-movable scraper for supplying large amounts of the powder/granular material and a fixed small scraper for supplying small amounts thereof. Said scrapers block the flow of the powder/granular material in the powder/granular-material discharge groove in the rotating disc and guide same to a discharge opening. This configuration makes it possible to increase the precision with which the powder/granular material is supplied.

Abstract: In a gas feeding apparatus for a powder and granular material feeder, in which a powder and granular material 3 supplied to an upper portion tubular hopper 11 is continuously supplied and discharged downward by a powder and granular material feeder provided below the tubular hopper 11, a first feed port 20 for a gas is provided in an upper surface 1a of a bottom plate 1′ on a lower surface of a boss portion for a set of rotary blades 8 of the powder and granular material feeder so that the gas can be fed to a space S between the upper surface 1a of the bottom plate 1′ of the powder and granular material feeder and the lower surface of the boss portion. Further, an annular damming plate 22 is formed on the lower surface of the boss portion on the outer side of the first feed port 20 so that the gas fed into the space S through the first feed port 20 can be fed in a radial direction into the powder and granular material feeder via slits 23, 24 provided around the annular damming plate 22.
