Operating Principle
The compressed air is cooled, 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 several nozzle jets, resulting in intense collisions, friction, and shearing for ultra-fine particle crushing. The crushed material is then transported by an upward airflow to the impeller classification area. Under the action 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 under their own gravity for further crushing, while qualified fine particles are carried by the airflow into the cyclone collector. Micro-fine dust is collected by the bag dust collector, and the purified gas is exhausted by the induced draught fan.
Performance Advantages and Features
On the basis of the traditional fluidized bed mill design, incorporating our company's exclusive self-flowing classification technology, it far exceeds the performance of domestic and international fluidized bed air classifiers.
1. Low energy consumption, saving up to 30% compared to traditional fluidized bed air grinding machines.
2. Equipped with an internal self-flowing micro-fine classifier, the particle size distribution is concentrated, and there are no oversized particles in the finished product.
3. The equipment boasts a compact structure with minimal land area required.
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, 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 gas as the medium, with the inert gas 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, with production capacities from 5 to 3000 kg/h available.
8. Vacuum production, free of dust pollution, with an excellent environment.
High level of automation, strong stability, and easy operation.
