《大有洞》矿山选矿车间的工人和技术人员们把分级机溢流堰长度改为改进前的4.3倍以后,磨矿机的处理量提高了10%,分级机的效率提高6.6%。在改进前,当增加磨矿机的处理量时,在分级机中产生矿砂堆积及矿浆面的波动现象,从而形成了很厚的溢流层。这样,在溢流产物中含有不少未单体分离 After the length of the classifier overflow weir was changed to 4.3 times that of the previous one, the throughput of the mill increased by 10% and the efficiency of the classifier by 6.6%. Before the improvement, when increasing the processing capacity of the mill, ore deposits and fluctuations in the slurry surface were produced in the classifier, resulting in a thick overflow layer. In this way, there is a lot of non-monomer separation in the overflow product
