Airflow classifier is graded according to granule gravity
Laboratory small airflow grinding for the specific application of experimental equipment, the final effect has been included in the Chengdu University of Technology, Southwest University of Science and Technology, China Nuclear Industry Physics, China, China Weapon Industry, Xi'an 213, Guangzhou Non-ferrous metal research institute, Northwest Non-ferrous Metal Research Institute, Jilin University, Xi'an University of Technology, Xi'an University of Science and Technology, Xi'an Jiaotong University, Beijing Mining Research Center, Chemistry Center, Chinese Academy of Sciences, Oriental, Lanzhou University, Southwest Petroleum University, Xi'an Domestic colleges and universities such as Yuanfei Airlines, Nanjing University, Inner Mongolia University of Technology, Central South University, and the uniform recognition of scientific research units have also chosen small air flow grinding for industrial processing.
The so-called grading is different from the granules and dielectric resistance of the particles of the material (e.g., air or water) depending on the particles of the material (e.g., air or water), thereby producing different motion trajectories. Hierarchical technology has wide application in mineral processing, environmental protection, building materials, metallurgy, fuel, chemical, ceramics, food and other industries, and under the background of energy conservation and emission reduction in the country, research on grading technology research and grading equipment, Be more and more attention from research institutes and manufacturers. Among them, the airflow classifier is one of the important research and development equipment, which has the advantage of high grading precision, particle size adjustable, no pollution.
The airflow classifier is a different level using particles in gravity and air flow resistance. The rotor impeller of the airflow classifier is a composite bidirectional centrifugal, and the impeller is high-speed, and the lower portion of the impeller forms a negative pressure region. The air in the hierarchical cylinder enters the bottom of the impeller, and the outer leaf trail is discharged from the outlet, and the fine particles are sprayed Out of the circulation, under the action of the control loop, the air flow is rotated, and there is a sport in the axial direction and circumferential direction. The airflow flows inwardly in the hierarchical disc, and the upper exit of the impeller enters the lower impeller, and discharges from the lower impeller outlet. The gas stream moves downward in the cartridge, and then flows upward through the inner cylinder to the lower air inlet of the impeller, so that the cycle flows forms a cross circulating airflow. The material input from the star feed valve falls into a high-speed rotating tubing plate, and the metering ring is poured under the action of centrifugal force, and the material is submitted downward in the grading cartridge under the action of the gasket. Under the action of the cross airflow, the thick particle material is slipperyed from the wall of the control ring.In the collector, the fine powder is delivered to the airflow of the inner strip resistance above the rotor (the inner cylinder of the hierarchy), so that the raw material is divided into two parts, while the remaining air is rotor In the lower middle suction mouth, flow through the blade, spray the fine grain ring, the control ring, and then flow back from the center of the rotor to the rotor, and form a continuous automatic cycle of the week. Follow the excess air brought into the material and due to high leveling room temperature, excess gas is discharged from the remaining wind to ensure the balance of airflow in the classification, stabilize. Yu Fengkou sets a filter bag, so that the discharged air is not polluting the environment.
Shandong Erfai production airflow classifier for many years, its technical experience and equipment has been very mature, in China, Shandong Yerpa can be said to be the best in the first-grade accuracy, efficiency, and many powder production at home and abroad. Manufacturers use the airflow classifier provided by Shandong Erp, welcome users to come to consult!
