Apparatus for determining the angle of repose according to DIN ISO 4324, Dr.Pfrengle
The apparatus is used to control and test the angle of repose of powders or granulates.
For determination, the test material is passed through a standardised funnel fitted with a stirring blade.
The height of the cone formed beneath the funnel can be used as an indicator of the storage and flow properties of powders.
The flowability of materials is influenced by the surface properties of the particles, particularly particle size, particle size distribution and moisture.
Information about the angle of repose and flowability is necessary for storage and trouble-free automatic processing.
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 applied to other powders and granulates with comparable properties.
