A comparative study of flow properties of the explosive compound RDX is presented. The results were used to identify desirable free‐flowing characteristics in the powders. Various static and free‐flowing tests were conducted on the explosive powders. The results suggest that flow properties of the RDX powders tested were not influenced by particle size and surface roughness. However density, moisture content and cohesive strength between the particles had some effect on the flow properties. An increase in moisture content and cohesive strength of the particles reduced the flow rate. Whereas an increase in bluk density of the powders increased the flow rate.
