Working Principle
Compressed air is chilled, filtered, and dried before being directed through nozzles to form supersonic airflow into the crushing chamber. This fluidizes the material, causing accelerated particles to converge at the intersection of multiple nozzle jets, resulting in intense collisions, friction, and shearing for ultra-fine particle crushing. The crushed material is then transported by an ascending air current to the impeller classification area. Under the force of centrifugal force from the classification wheel and the suction power of the fan, coarse and fine particles are separated. The coarse particles return to the crushing chamber due to gravity for further crushing, while qualified fine particles are carried by the air flow into the cyclone collector. 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-flowing classification technology, it significantly outperforms domestic and international fluidized bed air jet mills in performance.
Low energy consumption, 30% more energy-efficient compared to traditional fluidized bed air classifier mills.
2. Equipped with an internal self-dividing micro-powder classifier, with particle distribution concentrated, and 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 material and blind spots, making it easy to disassemble, clean, and sterilize. It's convenient to switch between different varieties and meets GMP requirements.
5. Low-temperature, medium-free crushing, 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 completely enclosed for crushing using inert gas as the medium. The inert gas is recycled, resulting in extremely low loss.
7. Wide particle size range from 3 to 180 um, finished product particle size adjustable; 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, 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, breaking, and granule shaping of various dry powder materials.
