This blender series is similar to the three leaves rotatioal oar blender,the four wide leaves rotational oar blender KSX,whose functions as the round plate turbo-agitator,so it is widely used in jar fermenter,if using it combined with round plate turbine blender,can save energy largely.The common condition is μ<50000cp,n=10-400rpm,V=1~10m/s,Dj/D=0.2~0.6,and usually adopted 0.4,the wide blender is B/Dj=0.2,the narrow blender is B/Dj=0.125.

High efficiency axial flow,low shearing force,strong flow field can be  formed under the condition with baffle.The wide blade high efficiency impeller has a large liquid discharge capacity and can be operated in the situation of gas dispersion and others.
