“…We also gave discussion to optimal rotation speed of an agitating blade based on the granulation experiment. 17) In this study, attention was given to fill level of starting materials so that additional discussion can be made for optimal operating conditions of the high-shear mixer by referring to the discrete element method (DEM) simulation. The simulation was conducted by changing the fill level of starting materials to not only visualize the kinetic motion of particles in an agitating vessel but also make numerical assessment.…”

SYNOPSISA high-shear mixer was used to mix a two-component system different only in the density, which was subjected to DEM (Discrete Element Method) simulation. In the first place, the kinetic motion of particles in an agitating vessel was visualized to obtain the information on how particles different in granular density were mixed and segregated. Then, segregation index was defined to clarify the relationship of segregation index and density ratio with operational conditions. The conditions were also clarified for obtaining favorable mixing conditions while segregation was prevented. In other words, it has been pointed out that DEM simulation could be not only employed to readily understand the mixing and segregation conditions of particles in a mixer but also effective in determining optimal operational conditions for obtaining favorable mixing conditions even when the density ratio is different.
