PDA(particle dynamics analyzer system) was used to measure the flow velocity of particles in the XFD-12 flotation cell, the results show that tangential mean velocity in the radial direction changes from positive to negative in the flotation cell, naught point emerge in the medium of the radial direction ,it is where backward fluid emerge ,shear stress of backward fluid induce the particle detachment from bubbles .

汁算数据与实际矿石筛析结果都表明，紊流强度增大，泡沫中粗粒级含量减小。 4。用PDA在XFD-12型8L浮选机中测定的速度值，进行混合区、分离区、泡沫区紊流运动功率谱计算，得紊流脉动频率，混合区小于20Hz，分离区在20-30Hz之间，泡沫区在25-35Hz之间，浮选槽内紊流脉动以低频为主，且紊流脉动动能是混合区大于分离区大于泡沫区。
