摘要

We devised the particle size measuring method in which flour particles were statically floated in the airflow at a test section. Spherically equivalent diameter of the floating particle was obtained by an elliptical approximation of the image. It was well confirmed by the study that the measuring time was reduced to one third and that the accuracy of the equivalent particle diameter acquired by the floating method was of a good consistency with our established Laser-used 3-dimensional particle size measuring method.
