Abstract
A method bulk strength of powders uses acceleration forces to compact the powder into a small conical test cell that is rotated at high speed. Once the material is consolidated to a prescribed condition, the rotation is stopped, the outlet of the cell is exposed, and the cell is rotated again at increasing acceleration until material freely exits the cell. The forces generated on the powder in the cell are determined and used to compute the cohesive strength of the bulk material.
