金堆城钼业公司大选厂有XJK—5.8型浮选机二百余台,这种浮选机泡沫槽的工艺要求是: 1.每个系统处理矿量为每小时65～70吨; 2.每吨矿石用水量3.5～4吨; 3.硫精矿粒度为0.35μ～0.65μ的占65％以上; 4.钼精矿粒度为0.35μ以下占90％以上。 这种浮选机自1983年投产后,由于浮选机泡沫槽经常发生矿浆堵塞而不能正常生产,每次开车不到24小时,泡沫槽就堵死,被迫停车。我们曾在泡沫槽上边安装三根高压水管强制冲洗,用水量增加了3倍以上,但仍未能杜绝堵塞事故的发生。泡沫槽结构示意图见图1。
Jinduicheng Molybdenum Plant Election XJK-5.8 flotation machine 200 sets of Taiwan, the flotation machine foam tank process requirements are: 1. Each system to deal with the amount of ore per hour 65 to 70 tons; 2 Per ton of ore 3.5 to 4 tons of water; 3. Sulfur concentrate particle size of 0.35μ ~ 0.65μ accounted for more than 65%; 4. Molybdenum ore particle size of 0.35μ or less accounted for more than 90%. This flotation machine put into operation since 1983, the flotation tank foam blockage often occur due to pulp and can not be normal production, each drive less than 24 hours, the foam tank is blocked, was forced to stop. We have installed three high-pressure water pipes on the foam tank for forced flushing, which has increased the water consumption by more than three times. However, it still failed to stop the plugging accident. Bubble tank structure diagram shown in Figure 1.
