摘　　要：介绍目前国内单槽容积最大的浮选设备——200m3超大型充气机械搅拌式浮选机的结构、工作原理,详细阐述槽体、泡沫槽、叶轮、定子等关键部件的结构设计和液位自动控制策略和方法的选择。通过浮选动力学试验和矿浆试验验证了浮选机整机性能,在试验期间设备运行平稳,泡沫层稳定,没有翻花、沉槽现象,泡沫层厚度可根据工业要求进行调节,液位自动控制系统工作正常,控制精度满足工艺要求,其选别性能与综合技术指标达到了国际同类设备的先进水平。The structure and now, are described, an principle of 200m^3 air forced flotation machine, the largest flotation machine in China d the structure design of the key parts, including cell, launder, impeller and stator, and the control strategy and method of level automatic control system are indicated in detail. Through the flotation dynamics test and pulp test, the flotation machine performance is verified. During the trial, the operation of equipment is smooth, the foam layer is stable, the foam thickness can be adjusted in accordance with industry requirements, the level automatic control system is good, the control accuracy meet the technological requirements. The technical and processing capability of the 200m^3 flotation machine is advanced which is meet the request for the large-scale flotation cells.
