The performance of orthopedic materials directly affects the performance of lithium -ion batteries, and its cost also determines the cost of battery. At present, lithium battery positive materials that have been market -oriented include lithium cobaltate, lithium manganate, lithium iron phosphate and ternary materials. The positive electrode material usually uses the air flow crusher to perform ultra -fine processing. Let's talk about the principle and effect of the positive material air flow crusher.
The working principle of the orthopedic material air flow crusher: The airflow crusher and the whirlwind separator, the dust collector, and the induction aircraft form a set of crushing systems. After the compressed air is filtered and dried, it is sprayed into the crushing cavity at a high speed through the Rawar nozzle, and the materials at the intersection of multiple high -pressure airflows are repeatedly collided, rubbing, cutting and crushing. Under the strong corporal effect of the high -speed rotating hierarchical turbine, the thick and thin materials are separated by the high -speed rotating turbine. The fine particles that meet the particle size requirements enter the cyclone separator and the dust collector through the hierarchical wheel. . The main factor affecting the effect of the air flow crusher of the positive material: 1. The temperature of the work quality is increased due to the increased temperature. Taking the air as an example: the critical speed at room temperature is 320m/s, and when the temperature rises to 480 ° C to 480 ° C The critical speed can be increased to 500m/s, that is, the kinetic energy increases by 150%, so it is beneficial to the effect of improving the temperature of work quality. The temperature of overheating steam when crushing titanium BAIFEN is generally about 300 to 400 ° C. Usually the temperature is high when the shattering is crushed, and the material after the surface treatment is lower, because some surface treatment agents, especially the organic surface treatment agent is not resistant to high temperature, is not resistant to high temperature. Sometimes you only need to overheat 100 ° C on the basis of the original steam temperature. 2. The pressure of work quality for work quality is the main parameter of the jet flow speed, and it is also the main parameter that affects the crushing fineness. The kinetic energy of the working -quality jet is proportional to the square of its quality, which is directly proportional to the square. Therefore, the higher the pressure, the faster the speed, the greater the momentum. Although the air flow rate no longer increases, the pressure increases, and the density of the airflow increases with it, and the same kinetic energy increases accordingly. As for how high pressure to choose when crushing, it depends on the crushing and fineness requirements of things. When using the heat steam to smash the titanium Baifen, the steam pressure is generally 0.8 to 1.7MPa. The material can be lower. The orthopedic material airflow crusher is one of the special products produced by Qingdao Youmingke. For the different nature of the positive electrode materials, the MQW fluidized bed gas flow crusher is used to control the high -essence turbine rotation system.
