在金属矿和非金属矿选矿过程中,有很多生产机械的单机功率不超过20～40kW,但是它们的总数量是相当大的。我们现在来研究选矿最终成品物料(精矿)过滤过程中使用大功率半导体整流器和继电控制电路以
In the mineral and non-metallic mineral processing process, there are many production machinery stand-alone power does not exceed 20 ~ 40kW, but their total number is quite large. We are now going to study the use of high-power semiconductor rectifiers and relay control circuits in the final beneficiation process (concentrate) filtration of beneficiation
