How to control the pulverized particle size

　　The ultrafine pulverizer performs particle size control. The main applied mechanism of ultrafine pulverizer determines its application range, high finished product, typical materials are: super hard diamond, silicon carbide, metal powder, etc., high purity requirements: ceramic color, medicine , Biochemical, low temperature requirements: medicine, PVC. By change the ordinary air of the gas source to nitrogen, carbon dioxide gas, etc., the unit can be made into an inert gas protection device, which is suitable for the pulverization classification of materials such as flammable explosive, easy oxidation. When the particle size of the finished product changes, the amount of feed should also be changed. When the hierarchical impeller speed is increased or the air volume is reduced, the particle size of the finished product is thinner, resulting in an increase in the amount of pulverization in the unit to increase the current value of the pulverized motor and the hierarchical impeller motor, and vice versa. The higher the speed of the hierarchical impeller, the finer the graded particle size (i.e., the particle size of the finished product), and vice versa, thicker. It is also possible to adjust the particle size of the finished product according to the change in the air of the fan; if the ventilation of the ventilator is large, the particle size of the finished product is thick and the air volume is small, and the particle size of the finished product is fine. The amount of feed should also be reduced or increased.

　　In the production process, it is necessary to ensure that the product particle size and feed amount must be adjusted without overloading the pulverized motor and the grading motor current. The ultrafine pulverizer is an apparatus for ultrafine pulverization of dry materials using air separation, heavy polishing, and shear. It consists of a cylindrical crushed chamber, a polishing wheel, a polishing rail, a fan, a material collection system, and the like. The material enters the cylindrical pulverizing chamber by the feed opening, and is crushed by the polishing wheel that is circumferential movement along the grinding rail, and dissensibly. The pulverized material brings out the pulverizer through the negative pressure air flow caused by the fan, into the material collection system, filtered through the filter bag, the air is discharged, the material, the dust is collected, and the pulverization is completed. The main applied pulverization mechanism determines the characteristics of a wide range of applications, high finished products, typical materials are: super hard diamond, silicon carbide, metal powder, etc., high purity requirements: ceramic color, medicine, Biochemical, low temperature requirements: medicine, PVC. By change the ordinary air of the gas source to nitrogen, carbon dioxide gas, etc., the unit can be made into an inert gas protection device, which is suitable for the pulverization classification of materials such as flammable explosive, easy oxidation. By the gas stream from the pulverized material into the hierarchy, the gas stream is brought into the inner wall and the shunt cover, and then the pneumatic force and the balance of the censored force active on the rotation hierarchy. SeparateThe coarse material returns from the inner cavity of the diverted cavity to the pulverized cavity, and the fine particle material (finished) is suiled into the hierarchy wheel, enter the discharge chamber, enter the current flow system through the unloading port, and finally the bold material separated from The inner cavity of the shunt is returned to the pulverized cavity, and then the fine particle material (finished) is suiled into the hierarchical impeller and enter the discharge chamber.
