In recent years, with the development of technology, it has brought a line of vitality to the beginning of the new industry. Many chemical industries, polymer materials, such as carbon black super microfinance, etc. What are the factors of the crushing efficiency of the air flow crusher equipment? Let's take a look with Xiaobian.
The gas ratio in the process of crushing of the airflow crusher is an important technical parameter and important indicator. If the gas ratio is too small, the kinetic energy of the airflow will be insufficient, which will affect the fineness of the product. However, if the gas ratio is too high, it will not only waste energy, but even the decentralized performance of certain pigments will deteriorate.
The granularity of the feed in the feed and crushing the hard material has stricter requirements for the particle size of the feed. In the case of titanium powder, when the shattering material is crushed, 100-200 mesh needs to be controlled; the material after crushing the surface treatment is generally 40-70 mesh, which cannot exceed 2-5 mesh.
When the temperature of the working fluid is too high, the flow rate of the gas will increase. Taking air as an example, the critical speed at room temperature is 320 meters per second. When the temperature rises to 480 ° C, the critical speed can increase to 500 meters/s, that is, the kinetic energy increases by 150%. Therefore, improving the temperature of the work fluid is conducive to improving crushing.
Work pressure. It is understandable that the pressure of the working fluid is the main parameter of the speed of the shot and the main parameter that affects the crushing fineness.
Generally, the higher the pressure of the work fluid, the faster the speed, and the greater the kinetic energy. So, how much pressure should you choose when crushing? The technician believes that this mainly depends on the mixed and fineness requirements of the materials. For example, when the titanium powder is crushed by overheated steam, the steam pressure is usually 0.8 to 1.7 mega Para, and the crushed burn materials are usually higher, and the materials that are crushed on the surface can be lower.
