该泡沫分选机包括初始产品分选槽和矿浆分配器、泡沫产品精选槽和与泡沫产品分选槽连接的控制分选槽以及泡沫收集和槽内产品排出的装置、设在槽内的压缩充气器,设在初始产品分选槽和控制分选楷之间的空气提液器,空气提液器壁的上缘高出槽的本身,这些分选槽串联设置。为了优化其充气和液体动力学条件,以提高分选过程的指标,分选机设有插入装置,设于空气提液器中,并遮盖横截面的40—60％,空气提液器壁的上缘与该槽的距离为该壁高度的0.2—0.5。 The foam separator comprises an initial product sorting tank and a slurry distributor, a foam product beneficiation tank and a control sorting tank connected with the foam product sorting tank, and a device for collecting foam and discharging the product in the tank, Compressed aerators, air extractors located between the initial product sorting tank and the control sorting tank. The upper edge of the air extractor wall rises above the tank itself, and these sorting tanks are arranged in series. In order to optimize its aeration and fluid dynamics conditions to improve the indexing of the sorting process, the sorter is provided with insertion means provided in the airlift and covering 40-60% of the cross-section, the airlift wall The distance between the upper edge and the groove is 0.2-0.5 of the height of the wall.
