Abstract

PURPOSE:To increase apparent specific gravity of discharged impalpable powder by vacuum-sucking to deaerate the powder, via a cylindrical filter at the middle portion of a trough in a screw feeder with the screw pitch prior to discharging reduced so as to compress the impalpable powder such as pigment or the like. CONSTITUTION:Impalpable powder in a hopper P is carried to a discharge cylinder 11 by a screw blade 19. The impalpable powder is sucked by vacuum through an annular chamber 9 at a position of a cylindrical filter to be deaerated and compressed by the screw blade 19a having a smaller pitch near the discharge cylinder 11. Accordingly, the impalpable powder is discharged from the discharge cylinder 11 as powder R increased in apparent specific gravity. Thus, the apparent specific gravity can be increased.
