概述在五十年代里,国外一些工业较先进的国家在选矿厂自动化方面虽然取得了某些进展,但是却远远落后于化工、石油和电站等工业部门。一般只解决了一些个别问题,例如,生产设备开停车的集中联锁,非磁性矿石用的金属探测器,磨矿机给矿量,分级机溢流浓度,浮选矿浆 pH 值,精矿干燥过程的温度和压力(或负压)等的自动测量与调节以及某些信号装置,多处于单参数自动测量与调节的局部自动化水
In the 1950s, some of the more advanced countries in the world made some progress in the automation of concentrator but lagged far behind those in the chemical, oil and power plants. In general, only a few individual problems are solved, for example, a centralized interlocking of parking facilities for production equipment, a metal detector for non-magnetic ores, a feed rate to a mill, a spillover concentration of a classifier, a pH value of a flotation slurry, The process of automatic measurement and regulation of temperature and pressure (or negative pressure), and some signaling devices, mostly in single-parameter automatic measurement and regulation of local automation water
