Operating Principle
The compressed air, after being chilled, filtered, and dried, is accelerated through nozzles to form supersonic airflow into the crushing chamber, causing the material to become fluidized. The accelerated material converges at the intersection of several nozzles' jet streams, resulting in intense collisions, friction, and shearing to achieve ultra-fine particle crushing. The crushed material is then conveyed by an ascending air current to the impeller classification zone, where it is separated into coarse and fine powders under the centrifugal force of the classification wheel and the suction force of the fan. The coarse powder returns to the crushing chamber by gravity for further crushing, while the qualified fine powder is carried by the air stream into the cyclone collector. The ultra-fine dust is collected by a bag filter, and the purified gas is exhausted by the induced draft fan.
Performance Advantages and Features
On the basis of the traditional fluidized bed mill design, combined with our company's unique self-fluidizing classification technology, it has superior performance compared to fluidized bed air classifiers both domestically and internationally.
Low energy consumption, 30% more energy-efficient compared to traditional fluidized bed air classifier mills.
2. Equipped with an integrated self-flowing micron powder classifier, the particle size distribution is concentrated, with no oversized particles in the finished product.
3. The equipment features a compact structure with minimal footprint.
4. The crushing box is free of leftover material and blind spots, making it easy to disassemble, clean, and disinfect. It is convenient to switch between varieties and meets GMP requirements.
5. Low-temperature, medium-free crushing, especially suitable for the crushing of materials with low melting points, thermal sensitivity, sugar content, and volatile substances.
6. For flammable and explosive materials, a full-sealed crushing process can be achieved using inert gases as the medium, with the inert gas being recycled, resulting in very low loss.
7. Wide range of particle sizes available, finished product particle size adjustable from 3 to 180 um; full range of machine types, with production capacities ranging from 5 to 3000 kg/h.
8. Vacuum production, free of dust pollution, with an excellent environment.
High level of automation, strong stability, and easy operation.
