PURPOSE:To increase the conveying capacity of high-speed air current per a unit for powser by forcedly pressing powder such as cement or the like stored in a tank into a transport pipe through an conduit pipe to uniformly disperse the powder in the high-speed air current flowing in the transport pipe. CONSTITUTION:Powder stored in a tank 2 such as cement or the like is forced to flow down to the lower portion of a casing portion 10 through a shutter portion 9. The cement is scattered from a discharge pipe 11 in a powder conduit pipe 14 by turning force of blades 12a of an impeller 12 (forcedly pressing means). At this time, acceleration and increased grade of scattering are applied to the cement by compressed air from an air pipe 15, whereby the cement is jetted from an opening portion 14b of the powder conduit pipe 14 in a transport pipe 3. The cement in the transport pipe 3 is dispersed by high-speed air current K to be transported with the high-speed air current K to a receive tank. Thus, the transport capacity of high-speed air current K per unit for powder can be increased. |
