玉石洼选厂是一座年处理量为100万吨铁矿石的磁选厂。原设计尾矿输送系统为6台8英寸泵,经(?)377毫米铸铁管输送到1.8公里外的尾矿池。由于尾矿粒度(0.15—0.18毫米)较粗,比重为2.6左右,尾矿浓度大于10%,输送管道坡度大,弯头较多,磨损造成漏矿现象比较严重。为此,我们一般在生产4—6个月,就将铸铁管翻转180°使
Jade stone processing plant is an annual processing capacity of 1 million tons of iron ore magnetic separation plant. The original design tailings delivery system for 6 8-inch pump, the (?) 377 mm cast iron pipe to the tailings pond 1.8 km away. As the tailings particle size (0.15-0.18 mm) coarser, the specific gravity of about 2.6, tailings concentration greater than 10%, the pipeline slope is large, more elbow, wear and tear caused by the phenomenon of more serious leakage. For this reason, we generally turn the cast iron pipe 180 ° to make it 4-6 months in production
