自磨机的设计是困难的，这是因其磨矿介质的可变性；当半自磨机或非自磨机中使用钢球或钢棒时，计算结果可靠得多，显然是因介质的特性是恒定的或可预测的。但当磨矿介质和给料完全相同时，给矿物理特性的变化使设计问题增多，特别是在第一段自磨机的情况下尤其如此。然而，芬兰奥托昆普公司的研究人员经过多年的全规模自磨生产磨机的研究之后，为研究矿石对“Outoenius”碎磨回路的适应性，采用“反向”研究的方法，正在研究一种专门的实验室方法。 The design of self-grinding mills is difficult because of the variability of the grinding media; when balls or bars are used in semi-autogenous or non-autogenous mills, the results are much more reliable, apparently due to the medium Characteristics are constant or predictable. However, when the grinding media and feedstock are exactly the same, changes in the physical properties of the ore give rise to design problems, especially in the case of the first-stage self-grinding machine. However, researchers at Outokumpu, Finland, have been investigating methods of “reverse” research to investigate the adaptability of ores to the “Outoenius” grinding circuit after many years of full scale self-grinding mill production A specialized laboratory method.
