我厂自1968年使用浮选柱以来,先后使用和试验了以帆布、苧麻、锦纶和聚氯乙烯为材料的充气器。由于浮选工艺要求使用大量石灰,导致充气器结钙和堵塞。为了解决这个问题,我们试验成功了床石充气器,于1971年4月投入生产,基本消除了结钙现象,获得良好效果。目前,我厂的浮选柱用于铜硫混合浮选尾矿选锌系统中,即用于锌的粗选和精选作 Since the flotation column was used in our factory in 1968, we have successively used and tested aerators made of canvas, ramie, nylon and PVC. Due to the flotation process requires the use of a large amount of lime, resulting in inflator caking and clogging. In order to solve this problem, we successfully tested the bed stone inflator, which was put into production in April 1971, basically eliminating the phenomenon of calcium formation and obtaining good results. At present, I plant the flotation column for copper and sulfur mixed flotation tailings zinc selection system, that is, for the rough selection and selection of zinc
