目前选矿开始采用了高效的(-1毫米)湿式筛分设备。由于湿式细粒筛分机械的产量低以及伴随着操作上的问题,尽管目前出现了名目繁多的设备,都无济于改观这些情况。表现在选矿方面,由于有用矿物一般均有不同比重与性质之矿石组成,所以难于在选矿方法上取得单一性,而终于出现“过磨”现象。长期以来,对细粒筛分机械发展作了种种努力,已出现了结构简单、产量高、磨耗低以及
The beneficiation begins with efficient (-1 mm) wet screening equipment. Due to the low production of wet-type fine-grain screening machines and the attendant operational problems, it is not possible to ameliorate these conditions in spite of the wide variety of equipment currently available. Performance in the beneficiation, the useful minerals generally have different proportion and nature of the composition of the ore, it is difficult to obtain unity in the beneficiation method, and finally “over-grinding” phenomenon. For a long time, various efforts have been made on the development of fine-grained screening machinery. Simple structures, high output, low wear and tear
