Airflow grinding can also reduce solid oxidants, explosives, and catalysts, and the combustion rate made of propellants can increase by 1 to 10 times higher than that of ordinary propellants, and improve the hit accuracy and power of the rocket engine. It is extremely important to realize the modernization of defense.The pearlescent pigment is composed of a plurality of metal oxide thin layers. Alter the thin layer of the metal oxide can produce different pearlescent effects. In the preparation of pearlescent pigments, the classification is an important part, directly affecting the results of the results. Shandong Elpai usually uses airflow grading machine to process pearlescent pigments, which has the characteristics of high grading precision, high processing amount and good stability. The airflow classifier is mainly used for the calcination molding process of the pearlescent pigment calciner, which is completely different from the process of the conventional water treatment.
The airflow classifier is mainly composed of airflow classifiers, cyclone separators, pulse dust collectors, high-pressure air blowers, electric control cabinets. The airflow classifier is mainly composed of secondary wind, three wind and impeller, transmission system. When the airflow classifier is working, the material is entered by the hierarchy of the grading machine under the action of the air blower. The air solid two-phase flow is sufficiently dispersed under the action of the air and the material of the airflow classifier and the discrete cone in the lower cylinder of the airflow classifier. When the air solid two-phase flow rises to the hierarchical region, each individual particles are subjected to centrifugal force generated by the graded rotation, and is subjected to a centering force generated by the air gravity. When the centrifugal force of the particles is greater than the heart force, the coarse particles above the fractionated diameter are smashed into the inner wall of the cylinder, and the inner wall of the tube is left to the secondary wind. Air is in the active force of the airflow classifier, and the secondary air inlet is evenly distributed across the tank, and the thick mixed powder is carried out. Thus, the fine particles mixed into the coarse are separated, reflowed to the classified area, and the crude particles are discharged from the unloading device. The airflow classifier meets the particle size required to enter the cyclonic collector with the airflow, and the pulse dust collector is collected, and the purified gas is discharged into the atmosphere through the air blower vent.
The water treatment process of the airflow classifier is to increase the whiteness of 5% percent of the white pearl powder, and the airflow classifier of the pearlescent pigment can be continuously treated after calcination, and the long distance connection is used as a pipe delivery, and the sealing class is not Will produce any dust, fromDynamic adjustment does not require manual control, the built-in no screen swirl grading, which has a good dispersed effect for the calcined fine powder and gold series under high temperature calcination. The airflow classifier not only removes impurities in the pearlescent pigment, but also effectively removes particles that cause fine powder and titanium white free black spots due to mica grading and hydrolysis, thereby improving the particle size distribution, color concentration, brightness, and recovery of pearlite. The particles can be added to the finished product to increase the finished cover.
The airflow grading model produced by Erli, Shandong is FW-200, which is also widely used in ore, chemical, metallurgy, battery materials, new materials and other fields.
As a classic industrial powder equipment manufacturing enterprise in Shandong, powder equipment is actively promoting the transformation and upgrading of traditional industries and high quality development. In recent years, in the implementation of the "One Belt" Initiative, ALPA Powder Technology has actively promoted the "Chinese Zhizhi" deep-moving global market with its independent commitment and organizing the ability to implement major projects, and sing "China" sound".
