Which is better for different collection methods of air jet mill? Umico Powder Machinery

As a commonly used superfine crushing equipment in industry, air flow pulverizer has always been famous and become the favorite of the powder processing industry. The finished powder materials processed by air flow pulverizer are characterized by high fineness (2-54 μ m), high efficiency, good dispersion and high purity, which are very suitable for high-end applications. The air flow pulverizer is generally used in rare, valuable and high value-added raw materials, such as diamond, white corundum, boron nitride, battery cathode materials, rare earth, etc. due to its relatively high energy consumption

Airflow pulverizer is that compressed air is accelerated into supersonic airflow through Laval nozzle and then injected into the crushing area to fluidize the materials, so each particle has the same motion state. In the crushing area, the accelerated particles collide with each other at the intersection of nozzles. The crushed materials are transported to the classification area by the updraft, and the fine powders that meet the particle size requirements are screened by the grading wheels arranged horizontally. The coarse powders that do not meet the particle size requirements return to the grinding area for further crushing. The qualified fine powder enters the cyclone separator with the air flow for collection, and the dusty gas is filtered and purified by the dust collector and discharged into the atmosphere< Br. This process has a very low primary yield, up to 90%, high energy consumption, and the waste heat of tail gas can not be used, which has been basically eliminated< Br/>At present, the air flow pulverizer mainly collects materials by dry method, that is, the materials from the air flow pulverizer enter the high-temperature bag filter for gas-solid separation. The current surface coated high-temperature resistant filter materials have a separation rate of more than 99.5%. The separated materials are discharged through the star discharger at the lower part of the high-temperature bag filter for cooling and packaging. The separated high-temperature exhaust gas is discharged from the air purification chamber at the upper part of the high-temperature bag filter, Enter the tail gas waste heat recovery unit for waste heat utilization< Br/>Any product will be gradually updated with the progress of the times and the demand of the market, and the same is true for jet mill. Qingdao Youmingke is the source manufacturer specializing in the production of air flow pulverizers. It is also the R&D and production base of large air flow pulverizers in China. Since its establishment more than 20 years ago, the air flow pulverizers produced by Qingdao Youmingke have continuously updated their processes and technologies, making the products more in line with user needs. The equipment is distributed in various industries at home and abroad
