Fu Shi brand three separation powder machine offer
The three-separation high-efficiency classifier is the latest technology product developed by the aerospace aerodynamic analysis method based on the most advanced principle of powder selection in the world. This product breaks through the "separate and fine powder" separation theory of the conventional closed-circuit grinding system, and divides the material into three, namely coarse powder, medium coarse powder and fine powder. The product system is simple in configuration, low in cost and large in size. The amplitude increases the mill output. The internal structure is reasonable and the powder selection effect is remarkable. It is the first choice for improving the quality of the grinding system after the implementation of the new cement standard, and guides the new trend of the technological innovation of the classifier.
The working principle of Fu Shi brand three separate separator
In the working state, the high-speed motor drives the vertical transmission shaft to rotate through the transmission device, and the material enters the powder selection chamber through the feed port provided at the upper part of the classifier chamber, and then passes through the upper and lower cones of the medium coarse powder collecting cone. The inter-powder and powder-powder pipes fall on the spreading disc, and the spreading disc rotates with the vertical transmission shaft. The material is evenly sprinkled around under the action of inertial centrifugal force, and the dispersed material enters the quenching chamber through the air inlet through the external fan. Under the action of high-speed airflow, the coarse and heavy particles in the material are forced to the inner wall surface of the powder selection chamber by the action of inertial centrifugal force. After the collision, the kinetic energy is slid down along the wall surface and falls into the coarse powder collecting cone. The remaining particles are rolled up by the rotating rising airflow. When passing through the action zone of the large wind blade, some coarse powder particles are It is thrown into the inner wall surface of the powder selection chamber. After the collision, the kinetic energy is lost along the wall surface and falls into the coarse powder collecting cone.
After passing the large wind blades, the medium coarse powder and fine powder continue to rise through the vertical guide vanes into the secondary powder selection zone under the action of the ascending air current. Under the action of the strong and stable plane vortex formed by the rotating cage rotor, the dust-containing airflow is thrown into the vertical guide vane by the centrifugal force and loses kinetic energy. It falls into the medium coarse powder collecting cone and passes through. The medium coarse powder tube is discharged. The fine powder that meets the requirements enters the interior through the cage rotor, enters the high-efficiency and low-resistance cyclone separator with the circulating wind, and then slides into the fine powder collecting cone to become the finished product.
Fu Shi brand three separate separator machine technical characteristics
Compared with the traditional classifier, the three-separation high-efficiency classifier has the following outstanding advantages:
1. The material is “divided into three”, that is, “coarse powder (d>150um), medium coarse powder (60um)
2. The Sepax three-separation high-efficiency classifier has a much higher output than the centrifugal, cyclone and rotor classifiers of similar size, and is therefore more suitable for large-scale production. The advanced and reasonable structure allows the powder volume, output and feed volume to be changed in a wide range without affecting the efficiency of the powder selection, and the classification performance is very stable.
3. The classification principle is advanced. Combined with a variety of powder selection principles, the aerodynamic analysis method was used to optimize the design of the entire flow field, resulting in significantly reduced equipment resistance and higher efficiency of powder selection. Energy saving and consumption reduction is very obvious. The rotor of the classifier is equipped with a vortex rectifier obtained by the state patent. The airflow in the rotor rises and does not rotate relative to the rotor. After the airflow enters the rotor, the momentum moment on the rotor is reduced, thereby saving driving power and reducing wear. The material is selected through two powder selection zones, and the classification accuracy is higher and more precise.
4. The spindle of the classifier adopts stepless high speed. The fineness adjustment is convenient, sensitive and reliable, and the adjustment range is wide.
5. Re-optimized and designed the spatial range of the powder selection area and the lifting area, making full use of the main space to increase the gas-to-gas ratio and improve the efficiency of powder selection.
6. The parts of the powder-removing machine that are vulnerable to wear and tear, such as the spreading disc, the cyclone cylinder, the snail angle, the wind guide vane and the rotor, are all made of wear-resistant materials or subjected to anti-wear treatment, and the wear rate is extremely low. The use of a new manganese plate effectively extends its service life.
7. The new bearing design of the lower bearing seal of the main shaft effectively solves two major problems of bearing dust and oil leakage, and effectively extends the service life of the lower bearing.
8. When designing the foundation of the powder selection machine, the principle of mechanical vibration reduction is adopted, so that the resonance frequency of the classifier and the foundation is not close to the natural frequency of the classifier, which fundamentally solves the vibration problem of the classifier that has long been plagued by the manufacturer.
9. The coarse powder pipe, the medium coarse powder pipe and the fine powder pipe all adopt double interlocking air damper, which greatly reduces the air leakage rate of the system and overcomes the defects of large dust in the operation of the previous classifier.
