Apparatus for evaluating fluidity of powder and method for evaluating fluidity of powder

摘要

PROBLEM TO BE SOLVED: To provide a slidability measurement method or the like of powder capable of easily measuring, in a short time, using trace specimens, the slidability of powder that continuously moves on a surface.SOLUTION: A slidability evaluation method of powder of the present invention includes the steps of: preparing a surface tilted from the horizontal surface by an angle that exceeds 0° and is less than 90°; applying a traveling wave vibration to the surface along the direction different from the tilt direction of the surface; and inputting the powder to be measured to a surface receiving the traveling wave vibration, and measuring the shape of the region in which the powder moving on the surface is distributed.
