Powder separator manufacturers introduce the working principle of air separation and classification!
The classifier is a powder classification device. It was originally mainly used in the production process of the cement industry, and has also been widely used in chemical, metallurgical and other industries. Under the actual working conditions, the materials to be sorted are fed from the upper feeding opening of the powder separator, and fall on the material spreading disc integrated with the rotor, which is thrown out in the radial direction under the effect of centrifugal force and dispersed in the powder selection chamber. .
The material meets the upward swirling airflow in the powder selection chamber. The fine particles in the material rise with the airflow due to the small mass, and are classified by the classification circle that rotates with the rotor. The qualified fine powder passes through the classification circle grid and continues to rise into the cyclone. After being collected by the cyclone, it falls into the ash collecting hopper and is discharged by the fine powder tube; the air after the fine powder is cleared is returned from the center of the cyclone through the air duct to the fan to form a closed-loop airflow; coarse particles are larger in the distribution tray and classification due to the larger mass Under the action of the ring, it separates from the fine materials, falls, and is discharged from the coarse powder tube. The thickness of the product can be adjusted by changing the speed of the spindle and the air volume of the fan.
A powder separator is used in the sand making process, and its main function is to separate the excess stone powder and useful particles and recycle them separately. Its working principle is: mixing gas and powder to form a gas-solid two-phase flow, the rotating spreading disc and high-speed air flow make the powder-containing air flow obtain centrifugal force during rotation, and the centrifugal force obtained by particles with different particle sizes is different, so as to achieve coarse and fine powder Grain separation. At the same time, the corresponding methods are used to recover the coarse and fine particles. The useful granules are the finished sand, and the unused fines are discarded.
The working principle of the powder separator, the digested lime powder is evenly dispersed into the dispersion area inside the powder separator through the upper feeding port, and the dispersed lime powder is sent to the ring separator at the upper end of the powder separator through the rising airflow. The powder area is sorted. Under the action of high-speed rotating vortex blades and horizontal partition plates, a balanced and stable horizontal rotary vortex powder separator sorting area is formed. The lime powder is classified with the wind pressure and air volume of the fan to achieve the finished product. The lime powder with particle size requirements enters the discharge outlet through the vortex blades and is collected by the cyclone separator through the pipe. It is removed through the discharge outlet below. The coarse powder and slag that does not meet the required particle size of the finished product are discharged through the slag outlet below the powder separator. . Advanced frequency conversion technology effectively improves the yield of the powder separator, so that the yield can reach more than 97%, and ensures the output and the fineness and purity of the finished product of calcium hydroxide.
The powder separator is designed and manufactured to meet the requirements of the new national standard for cement. It can collect 3-32um particles as much as possible during use. Fully notice the three main factors that affect the working efficiency of efficient powder separators: dispersion, classification and collection. Material Dispersion: Above the screw-type spreading pan, a new uniform distribution cone is newly designed to ensure that the material is evenly distributed on the spreading pan and fully dispersed. Material classification: The classification area is large enough to prepare for precise powder selection. Material collection: The newly-designed cyclone avoids the phenomenon of secondary dust, and the collection efficiency is particularly high. For easy-wearing parts, wear-resistant steel is lined, and even wear-resistant ceramic is pasted, which greatly extends the service life.
