What are the classifications of powder sorting machine manufacturers ?
There are many types of powder separators. Different types are suitable for different materials. Different models are also made according to customer requirements for material fineness. Commonly used powder separators include cyclone-type cyclone powder separators, three-separation powder separators , centrifugal powder separators, special separators for coal mills, and special separators for calcium powder. Later, many high-efficiency powder separators and high-efficiency three-separation powder separators have been developed. They are a new generation of varieties that have been improved on the basis of the original shortage.
Cyclone powder separator
The cyclone type powder separator uses a speed-regulating motor and drives 60 blades on the turntable to rotate through a secondary reduction to form a classification effect on the powder. The speed of the blade speed is adjusted according to the size of the finished powder. If you want to obtain finer-grained powder, you must increase the speed of the blades to increase the contact between the blades and the powder, so that the undesired powder is thrown by the blades to the outer wall to escape from the airflow, and the coarse powder falls into the force of gravity. The grinding chamber is reground. The qualified finished powder is sucked into the large cyclone collector by the blade with the airflow. After the airflow and the powder are separated, the powder is collected.
Three separation powder separator
The three-separation classifier breaks through the two-separation theory of "coarse and fine powder" of the conventional closed-circuit grinding system and divides the material into three, namely coarse powder, medium coarse powder and fine powder. Can greatly increase mill output. Its 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.
Centrifugal powder separator
Centrifugal powder separator is the first generation of wind classifier. The centrifugal powder separator has been transformed to solve the problem of high cycle load of the previous generation centrifugal powder separator, which can not only increase the mill output, reduce costs, but also improve product quality.
Centrifugal classifier is the first generation of classifier used in the cement industry. It was invented by the British Munfound and Moadie in 1885. For more than 100 years, with the advancement of technology and the increase in production process requirements, it has undergone a series of technical transformations and developed into a variety of structural forms, such as smnemam, cacco, Tso, and Heyd. The textbook structure and classification principle of these powder separators are similar. The common feature is that the powder selection airflow is internal circulation, that is, the gas separator, the circulation fan and the cyclone to collect fine powder are combined. This is also called internal circulation. Air powder separator. Using NHx high-efficiency rotor-type powder separator technology to transform the traditional centrifugal powder separator, Mingding can improve the efficiency of the powder separator and the output of the grinding system. This technology is especially suitable for the old line transformation with insufficient funding for technical innovation, low mill height, and difficult replacement of new high-efficiency powder separators, and has certain application value and market application prospects.
Pottery sand sorting machine
The pottery sand separator uses a high-distribution-capacity spreading disc, which enhances the spreading and swirling capabilities, enables the material particles to be fully dispersed and raised, and enhances the classification and dispersion performance of the material. The positions of the powder selection area and the lifting area were reasonably adjusted, and the powder selection efficiency was improved. The main shaft of the classifier can perform stepless speed regulation. Multi-level liner protection extends the life of the main unit. The advanced split-type detachable cage rotor is adopted, which greatly saves maintenance time and maintenance difficulty. The coarse powder tube and the fine powder tube adopt double interlock air valves, which greatly reduces the air leakage rate and overcomes the shortcomings of large dust during the operation of the previous classifier.
Fly ash powder separator
The classification principle is advanced. It adopts the organic combination of gravity centrifugation and cyclone vortex multiple classification force field to achieve high classification accuracy. The lower cage rotor can help the accumulated particles to rise again, increase the classification ability, and effectively reduce the fine powder content in the coarse powder. A speed-regulating motor is used to adjust the spindle speed, which is convenient for fineness adjustment, high sensitivity, and wide adjustment range. The powder selection area has been optimized and designed to enhance the space range of the area and improve the efficiency of powder selection. High-efficiency and low-resistance cyclone dust collector can effectively reduce fluid resistance and improve dust collection efficiency. A variety of anti-condensation devices such as flexible cleaners are optimized in the machine, and the anti-condensation effect is good. No-foot dust-proof vibration damping fan, easy to install, and low investment.
Slag powder separator
The slag powder is usually required to achieve a higher specific surface area during slag grinding. It is generally desirable that the slag powder has a specific surface area above 420 m / kg. When superfine grinding of slag, the average particle diameter of the material entering the powder separator is only about 10-12 μm, and the maximum particle diameter is only about 50-60 μm. Moreover, the density of slag is less than that of cement. At present, ordinary powder separators used in cement raw material and cement clinker grinding systems cannot meet the production requirements of slag grinding systems in terms of performance of spreading, classification and collection of finished products.
