美国克莱马克斯钼矿选矿厂将36槽№24(43″×43″)丹佛浮选机改为D—R型,水轮周速从1,500呎/分减少到1,240呎/分,功耗由5.4马力/槽降低到2.28马力/槽;保持了原有的浮选指标,实际上还稍有改善;浮选浓度为42％,给矿粒度为38%+10。目,仍能保持槽内的良好悬浮状态;运转一年后水轮磨损很少,减少.、了维修工作量。降低电耗而不影响选别指标,这是浮选厂的好经验,
The United States Clemex molybdenum ore concentrator to 36 № 24 (43 “× 43”) Denver flotation machine to D-R type, the water wheel speed decreased from 1,500 feet / minute to 1,240 feet / minute, power consumption by 5.4 horsepower / tank down to 2.28 horsepower / tank; to maintain the original flotation index, in fact slightly improved; flotation concentration of 42%, to the ore size of 38% +10. Head, still able to keep the tank in good state of suspension; running a few years after the wheel wear less, reduce the maintenance workload. Reduce power consumption without affecting the sorting index, which is flotation plant a good experience,
