Working principle:
The ultra-fine grinding and classifying machine precisely classifies materials based on differences in particle size, shape, and density through centrifugal force. The entire classification process is conducted without the addition of water, using a completely dry method, resulting in a narrower particle size distribution and non-polluting micro-powder. The equipment employs high-efficiency classification technology, wear-elimination technology, reliable sealing and non-leakage technology, large particle control technology, fine powder extraction technology, as well as the design of a complete and stable flow field and a constant gas-solid concentration ratio, ensuring the precision of classification and the control of product yield. With minimal wear, it is suitable for processing ultra-fine powders with high purity and ultra-narrow particle size ranges, avoiding wear issues associated with horizontal classifiers. Operating under negative pressure, the equipment prevents dust pollution and does not require a foundation pit, making it convenient for inspection and maintenance. Users can choose an online detection function based on their needs, enabling fully automated unmanned production operations.
Equipment features: The
Airflow Classifier consists of a feeding control system, classifier main unit (1-4 units), high-efficiency cyclone collector, pulse bag filter, high-pressure induced fan, and electrical control system.
Feeding Control System: Accurate and continuous control of the feed rate is achieved through a combination of a star feeder or vibrating feeder with a variable frequency controller.
Classifier Main Unit: Consisting of a motor,
Classifier Wheel, and cylinder, it effectively classifies materials by adjusting the classifier wheel speed and secondary air intake.
Classifier Impeller: Adjusted by a frequency converter and equipped with protection measures such as voltage loss protection, overcurrent protection, material level control, operation status monitoring, and alarm systems.
Cyclone Collector: As the primary collection system, it utilizes centrifugal force to guide the powder along the wall of the cylinder, separating and purifying the powder from the gas.
Pulse Bag Filter: Composed of a bag collection device, pulse dust removal device, and pneumatic control device, it utilizes high-grade diaphragm filter bags to achieve efficient dust removal.
