对异形水力旋流器分级特性进行了理论分析和实验研究。异形水力旋流器分级效果与工艺参数的关系总体趋势上与常规水力旋流器相同， 但在量值上存在一定差异。由于颗粒在异形水力旋流器内的回转曲率半径沿轨迹发生变化， 造成了颗粒沿旋流器径向振荡， 有利于细粒析出， 在预分级段利用异形旋流器的物料松散功能， 可获得良好的分级效果 The theoretical analysis and experimental research on the classification of heterogeneous hydrocyclones are carried out. The relationship between the grading effect of the shaped hydrocyclone and the process parameters The overall trend is the same as that of the conventional hydrocyclone, but there are some differences in the magnitude. As the radius of gyration curvature changes along the trajectory in the shaped hydrocyclone, the particles oscillate along the radial direction of the cyclone, which facilitates the precipitation of fine particles. By utilizing the material looseness function of the shaped cyclone in the pre-classification stage, Get a good grading effect
