Title: Method for measuring flow characteristic of powder
Inventor: SANNOMIYA KIMIE
IPC: G01N11/02
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To grasp the flow characteristics of powder in details. SOLUTION: Powder is loaded into a container 1 where the inner powder starts to flow down from an opening as the container 1 is inclined, the container 1 where the powder has been loaded is inclined, weight where the powder in the container flows down due to inclination is measured, and the inclination speed of the container is changed for statistically processing the fluctuation of the amount of powder that flows down and for measuring the flow characteristics of the powder. The deviation (correlation) between a step-shaped change appearing in a measured value when the inclination speed of the container 1 is changed and the change in the amount of flow-down being approximated by a straight line is obtained.  Or, the differential value of the step-shaped change is calculated, and the ratio of the standard deviation of the differential value to the amount of flow-down per unit angle is calculated.
