Working Principle
Compressed air is cooled, filtered, and dried, then formed into a supersonic airflow by nozzles, shooting into the crushing chamber to fluidize the material. 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 transported to the impeller classification zone by an ascending air stream. Under the force of the classification wheel's centrifugal force and the fan's suction, coarse and fine powders are separated. The coarse powder returns to the crushing chamber due to its own gravity for further crushing, while qualified fine powder is carried into 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 design of traditional fluidized bed pulverizers, our company's unique self-fluidized grading technology has been integrated, making its performance superior to that of 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 internal self-classifying micron powder separator, the particle size distribution is concentrated, with no oversized particles in the finished product.
3. The equipment features a compact structure and occupies a small footprint.
4. The crushing box is free of leftover materials and dead corners, making it easy to 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, an inert gas can be used as a medium for full-sealed crushing, with the inert gas being recycled for low loss.
7. Wide particle size range available, finished product particle size adjustable from 3 to 180 um; full range of machine models with production capacity options from 5 to 3,000 kg/h.
8. Vacuum production, dust-free environment, and excellent working conditions.
High level of automation, strong stability, and easy operation.
