Angle of repose meter

The injection limited bottom surface method is used to directly measure the dust resting angle, the funnel taper is 60 ° +/- 0.5 °, and the diameter of the material tray is φ 80mm, which is suitable for powder testing with different flowability.

Glass funnel and 0-100mm scale struts were used to measure powder flowability by fixed funnel method, which met the requirements of ISO 4324 and pharmacopoeia standards.
