Flowability Tester Accessories

The Angle of Repose is the angle (relative to the horizontal base) of the conical pile produced when a granular material is poured onto a horizontal surface. It is related to the density, surface area and coefficient of friction of the material concerned. The Angle of Repose Attachment comprises a 100 mm diameter circular test platform together with a digital height gauge, having a range of 0-300 mm and an accuracy of 0.03 mm. The test platform has a protruding outer lip in order to retain a layer of powder upon which the cone is formed. Surplus powder is collected in a tray below the test platform.

Providing a simple method for assessing the frictional characteristics of powders, the Angle of Repose module is ideal for predicting manufacturing issues associated with gravitational flow. Comprising a 100 mm diameter circular test platform together with a digital height gauge, powder heights of up to 145 mm can be easily read from the clear display. The tangent of the Angle of Repose (θ) is determined by measuring the height of the powder cone in mm and dividing it by 50. The inverse tangent of this figure provides the Angle of Repose in degrees.
