摘要
试图用理论分析方法来说明旋流闪速浮选对减少有价重矿物在磨矿分级回路中的过磨所起作用的原因。首先应用前人的研究方法,得出了旋流分选器中流场的三维速度的数值解,并在此基础上,经过合理的简化和抽象,应用平衡轨道理论.得出了旋流闪速浮选对目的矿物的分离粒度与结构参数和操作参数之间的函数关系,从理论上初步明确了旋流闪速浮选在磨矿分级回路中起作用的原因;并用上述理论分析了影响旋流闪速浮选的主要因素。
A theory analysis method is used to expound the contribution to reduction of overgrinding of the valuable high specific gravity minerals in the grinding classification circuits by cyclone flash flotation. Above all, three-dimensional distribution of velocity component in the fluid field is found through the basis theory of hydrodynamics refering to aniecessor's study. Then, the effect of structure and operating parameter of cyclone flash flotation on separation size of desirable particle is studied by the equilibrium orbit theory. Thus, the reason that cyclone flash flotation plays role in the grinding classification circuit is clarified fundamentally.
