Operating Principle
After being chilled, filtered, and dried, compressed air is directed 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 nozzle jet streams, resulting in intense collisions, friction, and shearing for ultra-fine particle crushing. The crushed material is then transported by an ascending air stream to the classifier area within the impeller. Under the influence of the centrifugal force of the classifier wheel and the suction force of the fan, coarse and fine powders are separated. The coarse powder returns to the crushing chamber due to its own gravity for further crushing, while the qualified fine powder enters the cyclone collector with the air stream. The ultra-fine dust is collected by a bag dust collector, and the purified gas is exhausted by the induced draft fan.
Performance Advantages and Features
Based on the traditional fluidized bed mill design, combined with our unique self-fluidizing classification technology, the performance is superior to that of domestic and international fluidized bed air classifiers.
Low energy consumption, 30% more energy-efficient compared to traditional fluidized bed air classifier crushers.
2. Equipped with an internal self-dividing micron powder grading machine, the particle size distribution is concentrated, with no oversized particles in the finished product.
3. The equipment has a compact structure and occupies minimal space.
4. The crushing box is free of leftover materials and blind spots, making it easy to disassemble, clean, and disinfect. It is convenient to switch between different varieties and meets GMP requirements.
5. Low-temperature, medium-free crushing, especially suitable for the crushing of materials with low melting points, heat sensitivity, sugar content, and volatile substances.
6. For flammable and explosive materials, full enclosed crushing can be achieved using inert gas as the medium, with the inert gas being recycled for low loss.
7. Wide particle size range, finished product particle size adjustable from 3 to 180 um; full range of models available, with production capacities from 5 to 3000 kg/h.
8. Vacuum production with zero dust pollution, ensuring an excellent environment.
High level of automation, strong stability, and easy operation.
