选矿的磨矿方式,在过去长时间内,基本上都是采用棒磨或球磨。采用这样的磨矿方式,矿石的粉碎比小,因此粉碎段数多,建设周期长,一般来说基建投资和生产费用较高。此外,棒磨和球磨都须用金属磨矿介质,当处理某些类型矿石时,矿粒表面会被介质细屑污染,也易产生过粉碎。自磨矿工艺就为克服这些缺点而创立的。本文拟就湿式自磨厂设计中的若干问题提出一些看法,供讨论。 Mineral processing methods of grinding, in the past long period of time, are basically using rod mill or ball mill. With such a grinding method, the crushing ratio of the ore is small, so there are many crushing stages and a long construction period. Generally speaking, the investment in capital construction and the production cost are high. In addition, the rod mill and ball mill must use metal grinding media, when dealing with some types of ore, the surface of mineral particles will be contaminated by the media fines, but also easy to produce over crushed. Since the grinding process to overcome these shortcomings and founded. This article intends to wet granulation mill design some of the issues put forward some views for discussion.
