Operating Principle

Compressed air, after being chilled, filtered, and dried, is accelerated through a nozzle to form a supersonic airflow, which is then射入粉碎室，causing the material to become fluidized. The accelerated material converges at the intersection points of multiple nozzles, resulting in intense collisions, friction, and shearing, thereby achieving ultra-fine particle reduction. The milled material is then conveyed by an upward airflow to the classifier area of the impeller, where it is separated into coarse and fine particles due to the centrifugal force of the classifier wheel and the suction force of the fan. The coarse particles return to the crushing chamber by gravity for further reduction, while the qualified fine particles are carried by the airflow 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

Based on the traditional fluidized bed mill design, combined with our company's self-flowing classification technology, it significantly outperforms domestic and international fluidized bed air jet mills.

1. Low energy consumption, up to 30% more energy-efficient compared to traditional fluidized bed air jet crushers.

2. Equipped with an internal self-flowing micro-finer separator, particle size distribution is concentrated, with no oversized particles in the finished product.

3. The equipment features a compact structure with minimal land area required.

4. The粉碎箱 is free of leftover materials, has no blind spots, is easy to dismantle, clean, and disinfect, allows for convenient variety change, and meets GMP requirements.

5. Low-temperature, medium-free grinding, particularly suitable for the grinding of materials with low melting points, heat sensitivity, sugar content, and volatile substances.

6. Flammable and explosive materials can be fully enclosed crushed using inert gas as the medium, with the inert gas being recycled for low loss.

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

8. Vacuum production, free from dust pollution, with an excellent environment.

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

Application Fields

Widely used in industries such as chemicals, mining, abrasives, refractory materials, battery materials, metallurgy, building materials, ceramics, food, pesticides, feed, new materials, and environmental protection, for ultra-fine crushing, disintegration, and granule shaping of various dry powder materials.
