众所周知,浮选法是选矿的重要方法之一,而浮选机又是实现浮选法的必要工具。尽管自50年代中期开始,在激烈的竞争中,低耗、高效、结构简单的大型浮选机得到了发展,浮选机流体动力学的研究已引起国外学者的注意,浮选柱近两年在西方和苏联再度兴起,目前国外大型浮选机应用于生产的不下20种。然而,实 As we all know, flotation method is one of the important methods of beneficiation, flotation machine and flotation method is to achieve the necessary tools. Although flotillators have been developed in the fierce competition since the mid-1950s with low consumption, high efficiency and simple structure, the research on fluid dynamics of flotation machines has attracted the attention of foreign scholars. In recent two years In the West and the Soviet Union once again rise, the current foreign large-scale flotation machine used in the production of no less than 20 species. However, real
