Compared with traditional powder separators, the three-separation high-efficiency powder separator has the following outstanding advantages:
1. Good performance and high efficiency. The three-separation powder separator "divides the material into three parts", namely "coarse powder (d>150um), medium coarse powder (60um 2. Compared with centrifugal, cyclone and rotor powder separators of similar size, the Sepax three-separation high-efficiency powder separator has a much higher output, so it is more suitable for large-scale production. The advanced and reasonable structure allows the powder selection air volume, output and feeding amount to change within a wide range without affecting the powder selection efficiency, and its classification performance is very stable. 3. Advanced classification principles. Combining a variety of powder selection principles, the entire flow field is optimized using aviation aerodynamic analysis methods, which significantly reduces the equipment resistance and makes the powder selection efficiency higher. Energy saving and consumption reduction are very obvious. The rotor of the powder separator is equipped with a nationally patented eddy current rectifier. The airflow in the rotor only rises relative to the rotor without rotating. The internal momentum moment of the airflow after entering the rotor is used to reduce the driving force on the rotor, saving driving power and reducing wear. The materials go through two powder selection areas to select powder, and the classification accuracy is higher and more precise. 4. The fineness is easy to adjust. As long as the rotation speed of the rotor is changed, the finished product can be controlled within the range of 250-500m2/k Blaine specific surface area. 5. The powder selection capacity is large. The space range of the powder selection area and lifting area has been redesigned and fully utilized to increase the material-to-gas ratio and improve the powder selection efficiency. 6. Long service life. The vulnerable and wear-resistant parts of the powder concentrator, such as the spreader plate, cyclone, snail angle, air guide blades and rotor, are made of wear-resistant materials or treated with anti-wear materials. Process treatment, its wear rate is extremely low. The use of new manganese plates effectively extends its service life. 7. The lower bearing seal of the main shaft adopts a new design solution, which effectively solves the two major problems of dust entering the bearing and lubricating oil leakage, and effectively extends the service life of the lower bearing. 8. When designing the foundation of the powder separator, the principle of mechanical vibration reduction is adopted so that the vibration frequency of the powder separator and the foundation is not close to the natural frequency of the powder separator, which fundamentally solves the long-term troublesome use. The manufacturer's powder concentrator has a vibration problem. 9. The coarse powder pipe, medium coarse powder pipe and fine powder pipe all adopt double interlocking air valves, which greatly reduces the air leakage rate of the system and overcomes the defect of large dust during the operation of the previous powder separator.
