浮选是细粒共生矿物分选的中心环节,虽然这种工艺的生产费用比较高,但却带来经济效益。故浮选机的研制一直受到特别重视。一般用分选精度作为评价浮选机结构合理性的主要标准有时也仅以可靠性作为主要的评定标准,大概也就是可靠性才确定了目前机械搅拌式浮选机的统治地位。然而,随着时代的变化,充气式浮选机很快占据了市场。目前许多类型的充气浮选机与机械搅拌式浮选机相比,不仅分选精度高,而且在可靠性方面也可与搅拌式浮选机相媲 Flotation is the center of finer grain symbiotic mineral separation, although the production cost of this process is relatively high, but it brings economic benefits. Therefore, the development of flotation machine has been given special attention. The general use of sorting accuracy as the main criteria to evaluate the structural rationality of flotation machines sometimes depend only on reliability as the main evaluation standard, which is about reliability to determine the dominance of mechanical agitation flotation machines. However, with the changing times, inflatable flotation machines quickly dominated the market. Currently, many types of aerated flotation machines are more accurate than mechanical agitation flotation machines and are comparable in reliability to agitated flotation machines
