Working Principle

Compressed air, after being chilled, filtered, and dried, 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 multiple nozzle jets, 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 impeller classification area. Under the force of the centrifugal force of the classifier wheel and the suction power 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 is carried by the air stream into the cyclone collector. 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

On the basis of traditional fluidized bed mill design, integrating our unique self-fluidized classification technology, its performance far surpasses that of domestic and international fluidized bed air classifier mills.

1. Low energy consumption, up to 30% energy saving compared to traditional fluidized bed air milling machines.

2. Equipped with an internal self-flowing micro-fine classifier, the particle size distribution is concentrated, and there are no oversized particles in the finished product.

3. The equipment features a compact structure with minimal land occupation.

4.粉碎箱 interior is debris-free with no dead corners, facilitating easy cleaning and sterilization. Variety changes are convenient, meeting GMP requirements.

5. Low-temperature media-free crushing, especially suitable for materials with low melting points, heat sensitivity, sugar content, and volatile substances.

6. Flammable and explosive materials can be fully enclosed crushed using inert gases as the medium, with the inert gases recycled, resulting in extremely low loss.

7. Wide particle size range, finished product particle size adjustable from 3 to 180 um; full range of models, with production capacity options from 5 to 3000 kg/h.

8. Vacuum production with zero dust pollution and an excellent environment.

High level of automation, strong stability, and easy operation.
