Abstract
Devices which have the structure of the polygon rotation drum are widely used in the manufacturing industries, e.g., for ball mill, for the mixing device, and for pharmaceutical tablet coating. One of the most important factors in design of these devices is particle mixture characteristic. The mixture characteristic affect on uniformity and efficiency of milling, and uniformity of particle or tablet coating in pharmaceutical industries.
Some baffles are installed in the rotation drum. The installation method of baffles influence on particle mixture characteristic. Therefore, we tried some kind of installation method of baffles, and estimated particle mixture characteristic at the surface of the particle bed in experiment.
In this paper, we applied DEM simulation on estimating particle mixture characteristic in the polygon rotation drum, especially focusing attention on each particle motion.
