Air Classifier

Working Principle:

The airflow classifier primarily consists of a feeding control system, classifier main body (1-4), efficient cyclone collector, pulse bag filter, high-pressure induced fan, and electrical control system.

1. Feeding Control System: It comprises a star feeder or vibrating feeder, combined with a variable frequency controller and feeding bin. It realizes continuous and constant-speed control of the feed material by adjusting the output frequency/current of the feeder.

2. Classifier Main Body: Mainly composed of a motor, classifying wheel, and cylinder, it achieves effective classification of materials by adjusting the rotation speed of the classifying wheel and combining it with reasonable secondary air inlet.

3. Classifier Impeller: Adjusted through a frequency converter, it features protective measures such as pressure loss protection, overcurrent protection, material level control, operation status monitoring, and alarm system.

4. Cyclone Collector: As the primary collection system for classified products, dust-laden airflow enters the cyclone collector, and due to centrifugal force, the powder slides down the cylinder wall and is separated and purified at the tail of the inner cone. The purified gas and a small amount of fine powder are discharged through the center tube of the cyclone.

5. Pulse Bag Filter: Composed of a bag collection device, pulse dust removal device, and pneumatic control device, its collection system utilizes our company's imported high-grade membrane filter bags.

Performance Advantages and Characteristics:

1. Centrifugal classification based on particle size, shape, and density, without moisture or washing, achieving narrower particle size distribution and pollution-free micropowder.

2. Features include efficient classification, wear elimination technology, reliable sealing, leak-free technology, large particle control, fine powder extraction, comprehensive and stable flow field design, constant gas-solid concentration ratio design, and technology to regulate the yield of a specific product brand.

3. Minimal wear: Can process ultrapure and ultra-narrow ultrafine powders, avoiding wear from horizontal classifiers. Under the same material, the service life of wearing parts is more than 5 times longer than that of ordinary classifiers.

4. High classification accuracy: Stable and complete classification flow field and special sealing measures reliably prevent coarse particle leakage, while the internal circulation of the vertical turbine classifier ensures qualified product particle size.

5. Full negative pressure operation, no dust pollution, no need for pit foundation, convenient for inspection and maintenance. Optional online detection and fully automated unmanned production can be achieved based on user needs.
