Narrow particle size distribution of materials processed by air flow pulverizer EPIC Powder Machinery

Xiao Bian is going to talk with you about the advantages of air flow crushing classifier today. The wearing parts of the ultra-fine crusher have low loss. All wearing parts are made of high-quality wear-resistant materials at home and abroad, with a long service life. A small number of easily worn parts are made of hard wear-resistant materials, which are small in size, light in weight and easy to replace accessories. After being filtered and dried, the compressed air of the air flow pulverizer is sprayed into the pulverizing chamber at high speed through Laval nozzle. At the intersection of multiple high-pressure air flows, the materials are crushed by repeated collision, friction and shearing. The crushed materials move to the classification area with the rising air flow under the action of the fan pumping force. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated, The fine particles that meet the particle size requirements enter the cyclone separator and dust remover through the grading wheel for collection, and the coarse particles drop to the crushing area for further crushing

The air flow crushing classifier is composed of a silo, a mechanical crusher, an induced draft fan, a cyclone, a vibrating screen, a liquid nitrogen tank, etc. The cryogenic crusher system uses liquid nitrogen as the cold source. After the crushed materials achieve embrittlement and easy crushing at low temperature through cooling, they enter the cavity of the mechanical crusher and rotate at high speed through the impeller. The materials and blades, toothed discs, materials and materials repeatedly impact, collide, shear, Under the comprehensive action of friction, the crushing effect is achieved. This is Xiaobian's introduction to the air flow pulverizer. As we all know, to choose products or services, we need to understand the processing, service, quality and other aspects of the air flow crusher classifier. After being crushed by the air flow pulverizer and classifier, the average particle size distribution of the material is narrow, the particle shape is uniform, the surface is smooth, the purity is high, the activity is high, and the dispersion is good. The low melting point and heat sensitive materials, biological products, and classifier air flow pulverizer can be driven by compressed air. The thermal expansion of the compressed gas in the nozzle will reduce the temperature of the system. The suction force generated by high-speed jet is distributed at a certain angle. The nozzle and the crushing chamber have the same level in the radius direction, and enter the crushing chamber through high-speed jet. The high-speed rotation of the material jet forms the hydrodynamic characteristics of the radius gradient of the crushing chamber, and the material particles collide with each other. Due to the high speed movement of the air flow and the inner wall of the grinding chamber, the materials have strong impact, friction and shear effects, resulting in wear of the grinding chamber and certain pollution to the products. The high-speed air blowing with an instantaneous speed of 20m/s is handled in the material equipment, and the material affects other high-speed movements. Because of the large air flow and the large impact strength of the material, the grinding efficiency is high and quite high. The movement of the human internal thread process in the spray gun and the maximum axial movement of the spiral cyclone separator material are collected to minimize friction and metal wall wear. Since the airflow crusher under the crushing chamber is equipped with a conical bottom, which enters the nozzle in the crushing chamber, the conical material can also be used for high-speed airflow nozzle and timely eliminate the crushing, blind spots, and ball media and materials under the crushing chamber. The rolling of cylindrical sphere, the irregular interaction of medium and material and the need for double action grinding, the grinding products are very thin and achieve uniform dispersion. The above are the advantages of air flow crushing classifier.
