Operating Principle
Compressed air, after being chilled, filtered, and dried, is directed through nozzles to form supersonic airflow into the crushing chamber. This causes the material to become fluidized, and as it is accelerated, it 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 then transported by an ascending air stream to the impeller classification area. Here, under the force of the centrifugal force from 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
Based on the traditional fluidized bed mill design, incorporating our company's exclusive self-fluidizing grading technology, it significantly outperforms both domestic and international fluidized bed air classifier mills.
1. Low energy consumption, up to 30% energy saving compared to traditional fluidized bed air grinding machines.
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 and occupies a small area of land.
4. The crushing box is free of leftover materials and blind spots, making it easy to disassemble, clean, and disinfect. It's convenient to switch between different varieties and meets GMP requirements.
5. Low-temperature, medium-free grinding, particularly suitable for the crushing of materials with low melting points, heat-sensitive, sugary, and volatile substances.
6. Flammable and explosive materials can be fully enclosed crushed using inert gases as the medium, with the inert gases being recycled for extremely low loss.
7. Wide range of particle sizes available, finished product particle sizes adjustable from 3 to 180 um; full range of machine types, with production capacities ranging from 5 to 3,000 kg/h.
8. Vacuum production, free of dust pollution, with excellent environmental conditions.
High degree of automation, strong stability, and easy operation.
Application Fields
Widely applied 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 granule shaping of various dry powder materials.
