Abstract
A method testing physical properties of bulk powder materials uses acceleration forces induce a change in physical configuration of a powder sample. Various different properties may be determined by relationships between the applied acceleration and the associated detected change in configuration event. In various embodiments powder strength, friction angle, or other properties may be determined. Novel methods and devices are provided.
Claims14
A method of determining a property of a bulk powder material, comprising;
- confining a sample of powder material within a cavity;
- applying acceleration forces to the sample;
- detecting a configuration change within the sample;
- determining an acceleration force applied at the time of the configuration change;
- and
- determining a powder property from the acceleration force applied at the time of the configuration change.
