英语翻译
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 disc

答案

在磨机的研磨介质类型中大小的减少和机械化学磨损是受磨球所有接触点的冲击,压缩,剪切和摩擦影响的.因此,为了开发新材料,找出研磨机制和生产超细粒子,了解球磨机中球的运动特点是非常重要的.
研磨介质搅拌磨由于它的高能源效率,精细,超精细粉碎能力和少污染在许多行业里已被用来作为超细磨机的一种类型,如矿产,陶瓷原料,化工产品及其他材料.[1-3]计算机仿真技术对研究颗粒流动的集合或分散特别是那种很难在直接实验中获得的详细结果是非常有用的.DEM是库德尔提出的一项模拟处理一个不连续的行为粒子系统的任何问题的方案[4],库德尔是第一个使用这种类型的模型来研究颗粒组件的人.从那时起,这些模型已被广泛应用在不连续的粒子系统模拟[5].对球磨机许多种类的模拟进行了研究：在歪斜状的磨机里球的三维运动[6,7],磨机的电源[8,9]和一个离心粉碎机功率[10].不过,到了现在,已经很少对搅拌磨研磨介质进行仿真研究.在搅拌球磨机里,与传统翻滚球磨机的简单动力学计算相比较,也有一些搅拌器和其消耗粉的计算变得更加复杂[11,12].
本文的目的是模拟在搅拌球磨机里研磨介质球的运动,并检查在以球与球之间和球与搅拌机之间所有的接触点微观互动的力量的基础上消耗的功率.
