The apparatus is used to check and test the angle of repose of powders or granules.
granulates. To determine the angle of repose, the test material is passed through a standardised
which is equipped with a stirring paddle. The height of the cone,
the funnel can be used as an indicator for the storage and flow properties of powders.
flow properties of powders.
The flowability of materials is influenced by the surface properties of the grains, in particular also by grain size, grain distribution and moisture.
For storage and trouble-free automatic processing, information about the angle of repose and the pourability is necessary. The International Standard describes a common method for determining the angle of repose of surfactants in powder or granular form and of washing powders. This method is also applicable to other powders and granulates with comparable properties.
