浮选柱被广泛而系统地应用于当今世界的选矿工艺生产中，特别是在最后的精选阶段．然而，浮选柱和传统的浮选槽在许多方面有差异，如捕收区和泡沫区域有差异，系统内气泡的产生和分配方式有差异，浮选柱泡沫顶部的冲洗水具有新作用，因而提供了不同的控制问题与时机．因为操作受各种因素的影响，所以需要测量可调变量，开发研制新模型和控制措施．大多数设备仍然利用传统的检测仪表监控，并采用传统的分布PI控制．如能较好地理解动力学，即可改进操作，更好地控制浮选柱．据文献报道，现已研制出浮选柱的表象模型，但大部分的模型参数必须从实验数据中得到．本文介绍了2个不同规格浮选柱的动力学特性实验研究，即用矩形断面为5cmx10cm、高为135cm的实验型浮选柱和直径为10cm、高为850cm的中间规模的浮选柱柱进行实验，以获取空气──—水系统的动力学关系．首先安装并校正了现场检测设备，将数据信号通过串联的A/D/A接口传送到PC计算机，然后，对气体变化、冲洗水变化和给矿量变化以及尾矿阀门的开度进行特定设计，以便获得在不同的操作条件下矿浆液面、充气量和偏流的特性曲线．获得各变量之间的非线性关系及相互作用的信息，对于解释普通控制问题非常重要．
Flotation columns are widely and systematically used in the beneficiation process in today’s world, especially at the final selection stage. However, there are many differences between flotation columns and traditional flotation cells, such as differences in catch and foam zones, differences in the way bubbles are generated and dispensed in the system, and flushing water at the top of flotation column foam has a new role, Thus providing different control issues and timing. Because the operation is affected by various factors, it is necessary to measure the adjustable variables and to develop new models and control measures. Most devices still use traditional instrumentation to monitor and use the traditional distributed PI control. If you have a good understanding of kinetics, you can improve the operation and better control of the flotation column. According to the literature, the flotation column imaging model has been developed, but most of the model parameters must be obtained from the experimental data. In this paper, experimental study on the dynamic characteristics of two flotation columns of different specifications was introduced. The experimental flotation column with rectangular section of 5cm × 10cm and height of 135cm and the intermediate-size flotation column with diameter of 10cm and height of 850cm Experiment to get the kinetics of the air-water system. The field test equipment was first installed and calibrated, the data signal was sent to the PC computer through the serial A / D / A interface, and then specific changes were made to gas changes, changes in flushing water and changes to the mine volume and tailgate opening In order to obtain the characteristic curves of the slurry level, the charge volume and the drift current under different operating conditions. Obtaining non-linear and interdependent information between variables is important in explaining common control issues.
