浮选厂浮选后的精矿如果含水过多,会使冶炼厂处理手续复杂和增加运输成本。为了减少精矿的含水量,就要经过乾燥炕,但其蒸发的有害气体严重的影响工人健康。故适当的改进脱水设备和操作,可以节省乾燥用的设备和人力直接得到含水率低的精矿。我厂采取改进圆筒型真空滤过机的措施后取得良好的效果。我厂圆筒型真空滤过机配置如图1。
Flotation concentrates after flotation of too much water, will make the smelter processing procedures and increase the cost of transportation. In order to reduce the moisture content of the concentrate, it is necessary to go through the dry kang, but the harmful gas evaporated seriously affects the workers’ health. Therefore, the proper improvement of dehydration equipment and operation, you can save drying equipment and manpower directly to the low moisture content of concentrate. I plant to take measures to improve the cylindrical vacuum filtration machine and achieved good results. I plant cylindrical vacuum filtration machine configuration shown in Figure 1.
