   Fine spherical aluminum powder is a main raw material of high-grade aluminum powder slurry, and it is also widely used. It is generally used in aluminum and gold materials, and steelmaking deaerators, especially aerated concrete foaming agents, have a very large demand. And, fine spherical aluminum powder can also be used in pesticides and gunpowder. Can be used as the main raw material of fireworks in gunpowder. The technical characteristics of fine spherical aluminum powder are as follows:
     1. The fine spherical aluminum powder can integrate pneumatic atomizing powder, particle size classification, pneumatic conveying, and powder packaging into a closed system. The production process uses nitrogen (purity 99.5%) as a protective gas, which can ensure high production. The quality of spherical aluminum powder also guarantees the safety of the production process. In addition, the atomizer designed and manufactured in large quantities according to the latest pneumatic atomization has a simple structure, low energy consumption, and can be used in 3. o ~ 5. Fine spherical aluminum powder was sprayed under OMPa pressure, and the average particle diameter was d50 <44 Hongm.
     2. The fine spherical aluminum powder is used in series with more advanced centrifugal and cyclone classifiers, which can separate more than 2 kinds of spherical aluminum powders with different particle sizes at one time, and the particle size range can be arbitrarily adjusted between d50 and 4-40 m. The classification accuracy can reach ± ​​1 3 / zm. In addition, the aluminum powder after particle size classification uses a dense-phase pulse pneumatic plug-flow air knife conveying device to the packaging department. The packaging process is performed in a semi-closed work box to prevent dust from flying and ensure production safety.
     3. The fine spherical aluminum powder can recover and recycle the nitrogen, and the gas consumption is less than 10m3 / h. And the equipment is designed according to the maximum explosion pressure of spherical aluminum powder (1.6MPa), and has a safety waterfall device. The fine spherical aluminum powder is equipped with a gas oxygen content measurement alarm device, which can be continuously fed into production. It can also be used alone as an aluminum powder classification device.
