Working Principle

The compressed air is chilled, filtered, and dried, then forms a supersonic airflow through the nozzle 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 to achieve ultra-fine particle crushing. The crushed material is transported to the impeller classification area by the rising airflow. Under the force of the centrifugal force of the classification wheel and the suction force of the fan, the 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 airflow. The ultra-fine dust is collected by the 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 unique self-flowing classification technology, its performance far exceeds that of domestic and international fluidized bed air classifiers.

Low energy consumption, 30% more energy-efficient than traditional fluidized bed air classifier mills.

2. Equipped with an internal self-flowing micro-powder grading machine, 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 area requirement.

4. The crushing box is free of leftover material and dead corners, 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, particularly suitable for the crushing 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 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 3,000 kg/h.

8. Vacuum production with zero dust pollution and excellent environmental conditions.

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, pharmaceuticals, ceramics, food, pesticides, feed, new materials, and environmental protection, for ultra-fine grinding, disintegration, and particle shaping of various dry powder materials.
