FJD multi-stage classifier

FJDSeries multi-stage classifier

1、 Working principle
The material enters the self splitting classification zone from the feeding system for the first classification. Most of the coarse particles are separated, and a small amount of coarse particles are carried by the rising airflow into the turbine classification zone for secondary classification. The fine powder enters the trap for collection through the classification wheel, and the coarse particles are discharged from the classifier discharge valve.
　　FJDThere are multiple types of multi-stage classifiersFJBThe classifier is connected in series to form a closed-loop system, which can simultaneously divide the powder into several particle size segments.
2、 Performance advantages and features The self splitting classifier is a new type of ultrafine classifier independently developed by our company, which is a perfect combination of self splitting inertia classification technology and centrifugal classification technology. Its core technology has reached the advanced level in the world today, and its technical performance has made a qualitative leap compared to the turbine classifier.
1Used for producing products with narrow particle size distribution requirements, the upper and lower limits of finished particle size are strictly controlled.
2Simultaneously producing products of several particle sizes, one classifier can replace several single-stage classifiers.
3Low energy consumption: With the same processing capacity, the energy consumption is reduced compared to other horizontal and vertical classifiers50%.
4High efficiency: With the same processing capacity, the classification efficiency is higher than other horizontal and vertical classifiers50%.
5High precision: The grading fineness is high, completely eliminating oversized particles and sieve residue in the product.
6Low speed: For the same grading particle size, the grading wheel speed is reduced compared to other horizontal and vertical grading machines50%Production of Mohs hardness<5When preparing the powder, there is no wear on the grading wheel; Production of Mohs hardness≥7When it comes to powder, the service life of the grading wheel is longer than other horizontal and vertical types5～8Twice.
7Complete structure: Specialized hierarchical structures can be configured according to different special requirements.
8It can form a closed or open circuit system with various grinding equipment such as ball mills, Raymond mills, impact mills, and air flow mills.
9Negative pressure production, no dust pollution, and excellent environment.
10High degree of automation, strong stability, and easy operation.
3、 Application scope
