抄録

The motion of balls in a tumbling ball mill was simulated numerically using the discrete element method (DEM). Simulations are performed for the two-dimensional and three-dimensional cases. To study the difference between two-dimensional and three-dimensional powder milling analyses, the ball motion was analyzed. It was found that there is no significant difference between the flow patterns for the two-dimensional and three-dimensional cases, but some properties such as the trajectory of the center of the gravity of the balls, the profile of the average velocity vector, the average ball velocity and the fluctuation velocities of the balls show significant differences.
