摘要： The present invention provides a powder material supply device, wherein a powder and/or granular material supplied to an inner cylinder 4 is pushed outward through a gap G by rotation of a rotary blade 8 and discharged from an outlet 18, the outlet 18 being arranged to satisfy the relation of L1 ≥ G × (1/tan X°)(wherein X° is an angle of response of the powder and/or granular material), with the shortest distance from the outer end of outlet 18 to a point directly below the inner circumference of the inner cylinder 4 on the bottom plate 2a being L1 (mm), and the dimension of the gap being G (mm). With such a powder material supply device, a fixed amount of powder and/or granular material mixing two or more kinds of powder and/or granular material can be supplied while suppressing a fluctuation in the content ratio.

摘要： The present invention is a metering feeder provided with the following: an annular transport space (5) formed by an outer cylinder (2), an inner cylinder (1), and a bottom plate (4); a central rotating blade (7) provided on a rotating shaft in the center of the bottom plate (4); an outer rotating ring (8) connected to the tip of the central rotating blade (7); a plurality of outer rotating blades (9) provided on the outer rotating ring (8) so as to point inwards; and a rotating disc (10) in which a powder/granular-material discharge groove (17) is formed, the top surface of said rotating disc (10) lying in the same plane as the top surface of the bottom plate (4). The outer rotating blades (9) scrape the powder/granular material in the annular transport space (5) into the powder/granular-material discharge groove (17), which transports said powder/granular material outside the outer cylinder (2). This metering feeder is further provided with a vertically-movable scraper (18) for supplying large amounts of the powder/granular material and a fixed small scraper (19) for supplying small amounts thereof. Said scrapers block the flow of the powder/granular material in the powder/granular-material discharge groove (17) in the rotating disc (10) and guide same to a discharge opening (13). This configuration makes it possible to increase the precision with which the powder/granular material is supplied.
