ABSTRACT

The discrete element code, EDEM, has been employed to simulate the axial mixing of size-binary particles in rotary kiln. Number of contacts has been introduced to track the progress of mixing and number of contacts between different particles has been took as mixing index between different particles to analyze the degree of mixing The results show that the larger velocity of particles in active layer is the main reason for the mixing; axial displacement of smaller particles is due to penetration of smaller particles through the intervals between larger particles.
