河北铜矿浮选铜精矿的脱水流程是:精矿由浓缩机浓缩后(排矿浓度60％固体),经4时砂泵(胶泵),送至过滤机中。在实现自动工作线以前,浓缩机的排矿、砂泵送矿,均为人工联系和操作(三个岗位,每班两名工人)。当过滤机需要给矿时,工人用电铃向砂泵、浓缩机岗位上的工人发出信号,砂泵工 Hebei Copper flotation concentrate copper concentrate dehydration process is: concentrated by concentrator concentrated (ore concentration 60% solids), after 4 sand pump (glue pump), sent to the filter. Prior to the realization of automatic work line, thickener row of ore, sand pumping ore are linked and operation (three positions, two workers per class). When the filter needs to be given to the mine, the workers use electric bells to send signals to the workers on the sand pumps and concentrator posts that sand pumps
