The size reduction and mechano-chemical grinding in a grind-
ing media type of mill are influenced by impact,compression,shear,
and friction at all the contact points of balls in the mill.Therefore,
understanding the behavior of ball movement in the mill is very
important to identify the grinding mechanism and to produce ultra-
fine particles for developing new materials.
Stirred grinding media mill has been used as a type of an ultra-
fine grinding mill in many industries such as minerals,ceramic ma-
terials,chemical products and other materials due to its high energy
efficiency,fine and ultra-fine grinding ability,and reduced contam-
ination [1-3].The computer simulation technique for studying the
flow of granular assemblies or powders is useful especially for ob-
taining detailed results from the task in that direct experimentation
is difficult.DEM is a scheme to simulate any problem dealing with
the behavior of a discontinuous particle system by Cundall [4],who
first used this type of model to study granular assemblies.Since
then,these models have become widely applied to the simulation
of a discontinuous particle system [5].Many kinds of simulations
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
calculation of its consumed powder becomes more complicated to
compare with the simpler kinetics of conventional tumbling ball
mill [11,12].
The objective of this paper is to simulate the motion of grinding
media balls in stirred grinding media mill and to examine the con-
sumed power based on the micro interactive forces at all the contact
points between balls and between ball and stirrer.
