Efficient powder separator
In order to overcome the shortcomings of centrifugal and cyclone powder separators, such as uneven spreading and uneven flow field, a batch of new classifying equipment was developed. The widely used O-Sepa type powder separator is considered as a typical representative of the third generation of efficient classification equipment.
The material enters through the feeding pipe, and is scattered into the rising airflow through the dispersion plate. Under the action of gravity, the grinding medium fragments in the material fall under the resistance of the upward airflow and are discharged from the slag discharge port. 的 The airflow with powder rises to the classification part, and enters the rotor through the guide vanes for classification. The guide vane can make the airflow and powder particles rotate, perform pre-classification, and capture the coarse particles thrown out by the rotor. It can also make the speed of the airflow evenly distributed throughout the height of the rotor. The coarse particles captured by the guide vane fall on the coarse powder cone and are discharged from the coarse powder outlet, while the fine particles and air flow enter the middle of the rotor through the rotor blade and are sent to the collection device through the fine powder outlet.
Performance advantages and characteristics
The high-efficiency powder separator has the following characteristics:
1. The material is dispersed outside the classification area. Due to the function of the dispersion plate, the intermediate connection duct and the guide vanes, it has both the static inertia classification and the dynamic classification functions.
2. The classification area of the high-efficiency powder separator is narrow and long, the air flow field is balanced and stable, the classification performance is good, and the classification efficiency is high.
3. The processing capacity of the high-efficiency powder separator is large, and the volume can be made smaller with other powder separators under the same processing capacity.
