介绍了几种不同规格压气式浮选机的技术性能。根据计算和工业试验结果 ,对使用这些型号的浮选机提出了一些建议。在浮选细磨的矿石和有价矿物含量较低的矿石时 ,采用加深槽 (大于 5m)的浮选机更为合理 ;深槽型 (3 -5m)浮选机适于浮选中等磨矿粒度的矿石 ;而半深槽型 (小于 3m)浮选机则适于浮选粗磨的矿石和连生体 ,以及在工艺流程的前部浮选有价矿物含量高的矿石 ,以分离出富的产品 (精矿 )。 The technical performance of several different specifications of flotation flotation machine is introduced. Based on calculations and industrial test results, a few suggestions are made for using these models of flotation machines. In the flotation of finely ground ore and ore with lower mineral content, the use of deepening tanks (more than 5m) is more reasonable for flotation machines; deep tank (3-5m) for flotation medium flotation Ore size; and the semi-deep trough (less than 3m) flotation machine is suitable for the flotation of rough ground ores and associated organisms, as well as the flotation of valuable mineral ores at the front of the process to separate Rich products (concentrate).
