云南海口磷矿擦洗厂年处理原矿60万吨,生产P_2O_5品位在30％以上的精矿48.6万吨,是目前我国最大的擦洗厂。 厂区最高处海拔2336米,上下高差67米,左右宽度60米,选矿设备全部露天化,与露天采矿场毗邻,风沙大。对面这一条件,如何改善操作工人的生产环境,立足国内,采用较新的技术,是电气设计人员与矿山领导需要考虑的主要问题。 一、主控制楼
Yunnan Haikou phosphate rock scrubbing plant processing 600,000 tons of ore, the production of P_2O_5 grade in more than 30% of the concentrate of 486,000 tons, is currently China’s largest scrub plant. The highest elevation of 2336 meters plant, about 67 meters above and below the width of about 60 meters, all mineral processing equipment, open air, and the open pit adjacent to the large sandstorm. Opposite to this condition, how to improve the working environment of production workers, based on the domestic use of newer technologies, is the major issue to be considered by electrical designers and mine leaders. First, the main control floor
