Analysis of ball movement for research of grinding

for the ball mill have been studied: the 3-dimensional behaviors of ball movement in a tumbling mill [6,7], the power of a tumbling mill [8,9], and the power of a centrifugal mill [10]. However, up to now, there has been little simulation research for stirred grinding media mill. In the stirred ball mill, there are some stirrers and the
