Abstract: Molecular dynamics is used to simulate binary granular of RDX and Al in a revolving drum.It shows that mixing quality is irrelative with filling method.In a drum without baffle plate on the wall,segregation of RDX and Al granule happens due to revolution of drum.With an added baffle plate on the drum wall,mixing effect is increased.Theoretical explanation is given for mixing and segregation.

Key words: explosive, mixing, molecular dynamics simulation
