Abstract: The experimental and numerical simulation researches on mixing and grinding of granular material in rotating drum equipments were reviewed. The existing problems in previous researches,including lack of investigations on axial mixing of granular material in small scale rotating drum and on mixing and grinding processes of granular material in industrial scale rotating drum equipments, and insufficient consideration of the mixing and grinding processes of particles of irregular shapes and micron sizes and mixed with water, are pointed out.It is recommended that the axial or overall mixing of granular material in rotating drums should be studied and that the similarity principle and the coarse grain model should be introduced into the discrete element modelling of dynamics of granular material in the rotating drum equipments in future work.On this basis, liquid-solid coupling models and relevant numerical simulation methods involving non-spherical particles should be developed.

Keywords: granular material; rotating drum; mixing; grinding; mill performance
