14m3浮选机是用于选矿、选煤的大型浮选机之一，为了探索影响浮选工作的主要参数，我们利用了正交试验方法，对该机进行了清水性能试验研究。一、因素分析及正交表的选择14m3浮选机的结构如附图所示．14m3浮选机的可变因素有抽管高度、进气门的开度、浸没深度，为了弄清浮选机
14m3 flotation machine is one of the large flotation machines used for beneficiation and coal preparation. In order to explore the main parameters that affect the flotation work, we make use of the orthogonal test method to test the performance of the machine. First, the factor analysis and the choice of orthogonal table 14m3 flotation machine structure as shown in the figure. 14m3 flotation machine variable factors have drawn the height of the intake valve opening, immersion depth, in order to clarify the flotation machine
