Operating Principle
Compressed air is chilled, filtered, and dried before being 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 nozzles, resulting in intense collisions, friction, and shearing to achieve ultra-fine particle crushing. The crushed material is then carried by an upward airflow to the impeller classification area. Here, the centrifugal force of the classifier wheel and the force of the fan separate coarse and fine particles. The coarse particles return to the crushing chamber under their own gravity for further crushing, while qualified fine particles are carried by the airflow into a cyclone collector. Ultra-fine dust is collected by a bag dust collector, and the purified gas is exhausted by an induced draft fan.
Performance Advantages and Features
Based on the traditional fluidized bed mill design, incorporating our company's unique self-flowing classification technology, it outperforms domestic and international fluidized bed air classifiers significantly in terms of performance.
Low energy consumption, saving up to 30% compared to traditional fluidized bed air classifier mills.
2. Equipped with an integrated self-flowing micro-finer grading machine, the particle distribution is concentrated, ensuring no oversized particles in the finished product.
3. The equipment features a compact structure and occupies a small footprint.
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, 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 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 3000 kg/h.
8. Vacuum production, free of dust pollution, with an excellent environment.
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, 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.
