A method for determination of the flow property of each powder was studied and a new method better reproducibility was established by evaluating the flow property with the speed of a rotating cylinder when a sample in the variable rotating cylinder (Fig. 1) is completely adhesive to the inner wall of the cylinder. Further, this method is can be used extensively for the determination of flow property of liquids like water, oils, and viscous liquids, and powder such as polysaccharides and inorganic salts. There was a correlation between the rotating speed of the cylinder and the angle of repose. Further, the effect of particle size and shape on the rotating speed of the cylinder was found.
