Operating 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. Accelerated material converges at the intersection of several nozzle jets, resulting in intense collisions, friction, and shearing to achieve ultra-fine particle crushing. The crushed material is then transported by ascending air currents to the impeller classification zone. Under the influence of centrifugal force from the classifier wheel and the suction power of the fan, coarse and fine particles are separated. The coarse particles return to the crushing chamber by gravity for further crushing, while qualified fine particles are carried by the air flow into the cyclone collector. Microscopic dust is collected by the bag dust collector, and the purified gas is exhausted by the induced draft fan.
Performance Advantages and Features
On the basis of the traditional fluidized bed mill design, incorporating our company's unique self-flowing grading technology, the performance of the mill surpasses that of domestic and international fluidized bed air jet mills.
Low energy consumption, 30% more energy-efficient compared to traditional fluidized bed air classifier mills.
2. Equipped with an internal self-flowing micro-powder grading machine, the particle size distribution is concentrated, ensuring no oversized particles in the finished product.
3. The equipment has a compact structure and occupies minimal space.
4. The crushing box is free of leftover materials and blind spots, 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, especially suitable for the crushing of materials with low melting points, thermal 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 being recycled for low loss.
7. Wide particle size range, finished product particle size adjustable from 3 to 180 um; full model range, with production capacity options from 5 to 3000 kg/h.
8. Vacuum production with zero dust contamination and excellent environmental conditions.
High degree of automation, strong stability, and easy operation.
