Powder Angle of Repose Measuring Instrument Powder Angle of Repose Tester
1. This dust angle of repose tester according to GBT 16913-2008 dust physical test method (injection limited to the bottom method)
2. Inject enough dust to fill the overflow tray into the horizontal tray from the funnel opening, and measure the acute angle between the dust accumulation slope and the bottom horizontal plane, i.e. the angle of repose of the dust.
Inner caliber 114.3mm
Inlet funnel : Taper 60° ± 0.5°
Outlet: 5mm diameter
Receiving surface: Diameter 80mm
Protractor: 7.5cm-10cm
Operation steps:
1. Place the instrument horizontally on the test bench and plug the funnel flow outlet with a stopper rod.
2. Load the sample into the sample container, scrape it with a spatula and pour it into the funnel.
Measurement process:
1. Remove the stopper and let the dust flow out of the funnel.
2. For poorly flowing dust, the dust can be stirred with a stick and needle so that the dust flows continuously down to the material tray.
3. After all the dust has flowed out, rotate the protractor to measure the acute angle between the dust vertebrae bus and the horizontal plane on the material tray, i.e. the angle of repose.
Should be measured several times: 3-5 consecutive measurements, to find the arithmetic mean A and the average variance a.
