How to change the classifier of a grinding mill to obtain a finer powder?

图片
(1) Increase the number of impeller blades Because the more blades there are, the probability of impact on the fly ash particles passing through the blades per revolution of the impeller is higher and the centrifugal force field generated is greater. The thickness of the blade should be chosen as thin as possible because the thinner the blade, the smaller the resistance to dust gas passing through the impeller. Of course, the determination of the parameters must also consider the impeller's rigidity, strength, and wear resistance. Excessively dense blades will increase the pressure loss and power consumption of the grading machine, as well as affect the normal grading. (2) Reasonable classifier casing design This is related to the shape of the classification room and the area. If the classifying chamber is too small, the fly ash powder will reflect randomly in the classifying chamber, making the turbulence very turbulent and affecting the normal classification. I...
