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.

是關於球磨攪拌機的，另：我不要翻譯軟體翻譯出來的東東

解答：

在磨機的研磨介質類型中大小的減少和機械化學磨損是受磨球所有接觸點的衝擊,壓縮,剪切和摩擦影響的.因此,爲了開發新材料,找出研磨機制和生產超細粒子,了解球磨機中球的運動特點是非常重要的.
研磨介質攪拌磨由於它的高能源效率,精細,超精細粉碎能力和少汙染在許多行業里已被用來作爲超細磨機的一種類型,如礦產,陶瓷原料,化工產品及其他材料.[1-3]計算機仿真技術對研究顆粒流動的集合或分散特別是那種很難在直接實驗中獲得的詳細結果是非常有用的.DEM是庫德爾提出的一項模擬處理一個不連續的行爲粒子系統的任何問題的方案[4],庫德爾是第一個使用這種類型的模型來研究顆粒組件的人.從那時起,這些模型已被廣泛應用在不連續的粒子系統模擬[5].對球磨機許多種類的模擬進行了研究：在歪斜狀的磨機里球的三維運動[6,7],磨機的電源[8,9]和一個離心粉碎機功率[10].不過,到了現在,已經很少對攪拌磨研磨介質進行仿真研究.在攪拌球磨機里,與傳統翻滾球磨機的簡單動力學計算相比較,也有一些攪拌器和其消耗粉的計算變得更加複雜[11,12].
本文的目的是模擬在攪拌球磨機里研磨介質球的運動,並檢查在以球與球之間和球與攪拌機之間所有的接觸點微觀互動的力量的基礎上消耗的功率.
