ANALYSIS OF MIXING MECHANISM OF WET PARTI CLE SYSTEM IN KNEADING PROCESS WITH DISPERSION MODEL

A mixing process for a wet particle system is advanced by using fundam ental operations such as compression, shearing, rolling, and folding. Here, we present a simulation method based on these fundamental operat ions in order to quantitatively understand the mixing process even in the microspaces between particles. We developed model experimental app aratus, and a simulation method based on a dispersion model, and compa red the results by both methods. Using the model analysis, the mixing process can be quantitatively understood until the micromixing of the wet particles is mutually completed. It was also found that a mixing p rocess proceeds rapidly and that the mixing state proceeds regularly a nd uniformly using proposed model operation that is dominated mainly b y the folding operation.
