从浮选最早于 1911年在美国蒙大拿州获得应用之后 80年的回顾、塔加尔特的 192 7年和 1945年出版的《选矿手册》和美国采矿工程师协会 1984年出版的《选矿手册》的数据、最近的生产厂家产品目录及 2 0世纪 80到 90年代的其它资料表明 ,随着浮选法的广泛应用 ,浮选机的规格日益增大。最早的机械式浮选机容积不到 1m3(3 5立方英尺 ) ,现在最大的浮选机容积已到 2 0 0m3(70 0 0立方英尺 )。浮选机大型化需满足三个要求 :1)证实大容积浮选机取代小容积浮选机的优点 ;2 )通过相关公式计算所需功率、叶轮直径和叶轮转速等参数 ;3 )考虑大浮选机配置时台数的减少对过程动力学的影响。本文列出 7个表说明了这些问题 ,并对这些问题进行了讨论 A review of the 80 years since flotation was first applied in 1911 in Montana, USA, the 2013 Metallurgical Manual published by Taggart and published in 1984 by the American Institute of Mining Engineers, The recent catalog of manufacturers and other sources in the 1980s and 1990s show that the specifications of flotation machines are increasing with the widespread use of flotation methods. The earliest mechanical flotation machines were less than 1 m3 (35 cubic feet) in volume, and the largest flotation machine now has a capacity of 20000 cubic feet (700 cubic feet). Large size flotation machine to meet the three requirements: 1) Confirm the advantages of large volume flotation machine instead of a small volume flotation machine; 2) Through the relevant formula to calculate the required power, impeller diameter and impeller speed and other parameters; 3) Effect of Decreasing Number of Flotation Machine on Process Dynamics. This article lists seven tables that illustrate these issues and discuss them
