浮选柱是新型的浮选设备,具有结构简单,处理量大,流程简化,投资省,生产费用低等优点,目前对处理金属矿高品位易选矿石或单金属矿效果较好,对非金属矿分选煤泥、磷灰石、硫铁矿也是有效的设备。 矿浆的充气是整个浮选过程的重要环节之一。对矿浆充气的要求,不仅有量的方面,而且也有质的要求。充气质量好坏,包括适宜的充气量,空气在矿浆中的分散度,气泡的上升速度及其在浮选设备中分配的均匀性等,不仅影响工艺指标、浮选速度,而且也影响浮选设备的充分利用。浮选柱属于单纯空气吹入式浮选机,柱内没有搅拌叶轮,其气泡的形成和弥
Flotation column is a new type of flotation equipment, with the advantages of simple structure, large processing capacity, streamlined process, investment saving, low production cost and the like. At present, flotation column is more effective in treating high-grade ore or single-metal ore with high grade, Metal ore separation slime, apatite, pyrite is also an effective equipment. Inflation of pulp is an important part of the flotation process. The requirements for inflating the slurry are not only quantitative but also qualitative. Aeration quality is good or bad, including appropriate aeration, air dispersion in the pulp, the bubble rise rate and its distribution in the flotation equipment uniformity, not only affect the process indicators, flotation speed, but also affect the flotation Make full use of the equipment. Flotation column is a simple air-blown flotation machine, column impeller is not mixing, the bubble formation and Mi
