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. 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 then transported by an upward airflow 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 the qualified fine powder is carried by the airflow into the cyclone collector. Microscopic 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 exclusive self-fluidizing classification technology, it outperforms domestic and international fluidized bed air classifiers significantly in performance.
Low energy consumption, saving up to 30% compared to traditional fluidized bed air flow crushers.
2. Equipped with an internal self-classifying micro-fine separator, the particle size distribution is concentrated, with no oversized particles in the finished product.
3. The equipment has a compact structure and occupies a small area.
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 varieties and meets GMP requirements.
5. Low-temperature, medium-free crushing is 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 gases as the medium, with the inert gases recycled for extremely low loss.
7. Wide particle size range, finished product particle size adjustable from 3 to 180 um; full range of models, with production capacities ranging from 5 to 3000 kg/h.
8. Vacuum production with zero dust pollution and an excellent environment.
High level 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 crushing, dispersion, and granule shaping of various dry powder materials.
