PROBLEM TO BE SOLVED: To provide a device so as not to separate a mixed material in discharge time by removing metal powder being foreign matter from a powder and granular material when discharging the powder and granular material from a vessel and a fluid collection hopper, and so as not to separate the mixed material in discharge time by restraining sticking of the powder and granular material by static electricity on an inner wall surface by the static electricity generated in fluid mixing and air transport time, in the present invention.SOLUTION: For attaining the purpose, a metal powder removal unit of a powder and granular material on the present invention comprises a vessel having a straight cylinder part of forming an upper side part for storing the powder and granular material in a substantially cylindrical shape, a taper part of forming a lower side part in a substantially inverse conical cylindrical shape and a discharge pipe for discharging the powder and granular material to a taper part lower end part, and is provided with the metal powder removal unit for the powder and granular material constituted of a conductive substance installed in a lower part of the taper part, forming a conical shape upward and united by joining an inverse conical-shaped object to a lower part, and constituted of a support member for storing a magnet on the inside and providing a cavity with the taper part.SELECTED DRAWING: Figure 1 |
