ACCELERATED POWDER SEGREGATION TESTING APPARATUS AND METHOD

摘要

An accelerated powder segregation testing apparatus and method are disclosed. The apparatus consists of an angularly oriented ramp 10 mounted on a vibration device 22. The powder to be tested is fed into an origin portion 14 of the ramp 10, and when the vibrator 22 is activated, the powder moves along the ramp 10. As the powder exits after the test, unit-dose powder samples are collected, compacted and analyzed for differential in content uniformity. By comparing the results from several formulations, the formulation that is most resistant to segregation can be selected for production.
