PROBLEM TO BE SOLVED: To provide a powder and granular material supply device that when supplying powder and granular materials from a hopper to a supplied part positioned below the hopper through piping, can prevent the powder and granular materials from being consolidated at the supplied part.SOLUTION: In powder and granular material supply piping 3 provided between a hopper 1 and a supplied part 2 positioned below the hopper is provided a pressure reducing member 4 with an inclined upper surface which reduces pressure which is applied to the supplied part when the powder and granular materials fall by contacting at least parts of the falling powder and granular materials therewith. Here, it is preferable that the pressure reducing member 4 is made of a member with a conical upper face and between an outer periphery of the member and an inner wall of the piping is formed a clearance d through which the powder and granular materials can pass.SELECTED DRAWING: Figure 1 |
