New Test Method for Standard Test Method for Determining Dynamic Angle of Repose using the GranuDrum
1. Scope
1.1 This method covers the apparatus and procedures for measuring the dynamic angle of repose for powders and bulk solids. 1.2 The maximum particle size of the specimen must be less than 2 mm. Note 1; Typically this device is used for testing powders in the range of 1 to 400 micrometers. 1.3 The most common use of this information is in determining various flowing properties that are useful in comparing properties of one powder to another (flowing angle, dynamic cohesive index, first avalanche angle and powder aeration). Parameters for Discrete Element Analysis (DEM) may also be derived from this data.Keywords
Dynamic Angle of ReposeRationale
This device is used by many people worldwide. It has been found to be useful as input for DEM simulations.
