Working Principle
Compressed air is chilled, filtered, and dried before being directed through nozzles to form supersonic airflow into the crushing chamber. This fluidizes the material, and as it is accelerated, it converges at the intersection of multiple jet streams, resulting in intense collisions, friction, and shearing to achieve ultra-fine particle crushing. The crushed material is then carried by an ascending air stream to the impeller classification area, where it is separated into coarse and fine particles under the force of the centrifugal force from the classification wheel and the suction force of the fan. The coarse particles return to the crushing chamber due to their own gravity for further crushing, while the qualified fine particles are carried by the air stream into the cyclone collector. Micro-fine dust is collected by the bag dust collector, and the purified gas is exhausted by the induced draught fan.
Performance Advantages and Features
On the basis of the traditional fluidized bed mill design, incorporating our company's exclusive self-fluidizing grading technology, it far outperforms both domestic and international fluidized bed air classifiers.
Low energy consumption, 30% more energy-efficient than traditional fluidized bed air mill.
2. Equipped with an internal 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 land footprint.
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, thermal sensitivity, sugar content, and volatile substances.
6. For flammable and explosive materials, a full enclosure crushing can be achieved using inert gases as the medium, with the inert gases recycled for extremely low loss.
7. Wide range of particle sizes, finished product particle sizes adjustable from 3 to 180 um; full range of models, with production capacities ranging from 5 to 3000 kg/h.
8. Vacuum production with zero dust pollution and excellent environment.
High level of automation, strong stability, and easy operation.
Application Fields
