Operating Principle
After being chilled, filtered, and dried, compressed air is formed into supersonic airflow through nozzles and injected into the crushing chamber, causing the material to become fluidized. The accelerated material converges at the intersection points of several nozzles' jet streams, resulting in intense collisions, friction, and shearing to achieve ultra-fine particle crushing. The crushed material is then transported by an ascending air stream to the impeller classification area. Under the centrifugal force of the classifier wheel and the suction force 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 qualified fine powder is carried by the air stream into the cyclone collector. 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, incorporating our company's unique self-flowing grading technology, it outperforms domestic and international fluidized bed air jet mills significantly.
Low energy consumption, 30% more energy-efficient compared to traditional fluidized bed air classifier mills.
2. Equipped with an integrated self-dividing micro-powder grading machine, particle distribution is concentrated, with no oversized particles in the finished product.
3. The equipment features a compact structure with minimal land occupation.
4. The crushing box is free of leftover materials and blind spots, making it easy to disassemble, clean, and sterilize. It is convenient to switch between different types and meets GMP requirements.
5. Low-temperature, medium-free grinding, particularly suitable for the grinding of materials with low melting points, heat-sensitive properties, sugar content, and volatile substances.
6. For flammable and explosive materials, full-sealed crushing can be achieved using inert gas as the medium. The inert gas is 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 available, with production capacity ranging from 5 to 3000 kg/h.
8. Vacuum production, free of dust pollution, with excellent environmental conditions.
High degree of automation, strong stability, easy operation.
Application Fields
Widely applied in industries such as chemicals, mining, abrasives, refractory materials, battery materials, metallurgy, construction materials, pharmaceuticals, ceramics, food, pesticides, feed, new materials, and environmental protection, for ultra-fine crushing, disintegration, and granule shaping of various dry powder materials.
