XCF/KYF型充氣機械攪拌式浮選機組
 Mechanical  agitating aeration flotation machine set

XCF型與KYF型浮選機均屬充氣型浮選機，葉輪直徑小，圓周速度低，可降低功率30-50%；槽內設有一個空氣分配器，因而空氣分散均勻；葉輪起離心泵作用，可使固體顆粒充分懸浮；采用U型槽結構，可使尾砂沉積最少；葉輪結構及葉片間隙流道設計合理，葉輪磨損較均勻，葉輪、定子使用壽命長。KYF型無自吸礦漿能力，功率較低；XCF型具有自吸礦漿能力，可水平配置，不需要泡沫泵，但功耗較KYF略高一些，因而一般都將XCF型和高KYF型配置成機組，XCF型為吸入槽，KYF型為直流槽，聯合機組可水平配置，不需泡沫泵。

Models XCF and KYF are enforced  aeration flotation machine. It has a smaller diameter of impeller, thus lower  peripheral speed, saving 30%-50% of power. Because and air distributor is equipped  in the tank, air is evenly dispersed. The impeller acts as a centrifugal pump,  so as to make the solid particles suspending. The tank is made as Utype,  reducing sand settlement to the least. Due to reasonable design of the impeller  structure and the impeller space,impeller wearing is even, so, the service life  of the impeller and stator are extended. Model KYF is unable to spontaneously  suck slurry, while has low power consumption. In contrast, model XCF has the  ability to automati-cally suck slurry, and may be allocated horizontally  without need for foam pump, but consumes more nower than model KYF. Thereore,  model XCF and model KYF are combined into a set, i.e., XCF as the sucking tank,  and KYF as the direct tank. The combined set can be arranged horizontally  without foam pump either.
