一、绪言细粉碎以及粉碎物的混合,在一般矿业中是不言而喻的。即使在近年迅猛发展的新兴材料工业中也是重要的工序。能够同时进行这两种作业的最普通的设备之一要算是球磨机了。然而球磨机与例如气流磨那样的细磨专用设备相比,其粉碎力小,要想得到几微米的粉体就不得不采取间歇式方法,并需要相当长的作业时间。其原因有二:(1)球磨机的粉碎力受到粉碎介质——球的工作 First, the introduction Fine grinding and crushing mixed material, in the general mining is self-evident. Even in the emerging material industry, which has been booming in recent years, it is an important process. One of the most common equipment that can perform both jobs at the same time is a ball mill. Ball mills, however, have less pulverizing power than fine grinding special equipment such as air jet mills and have to resort to a batch method to obtain powders of a few microns and require considerably longer working hours. There are two reasons for this: (1) The grinding force of a ball mill is affected by the crushing medium - the ball’s work
