Working Principle
Compressed air, after being cooled, filtered, and dried, is formed into a supersonic airflow through a nozzle and injected into the pulverization chamber. This fluidizes the material, and the accelerated material converges at the intersection of the jets from several nozzles, producing intense collisions, friction, and shearing to achieve ultrafine pulverization of the particles. The pulverized material is conveyed by the rising airflow to the impeller classification zone. Under the action of the centrifugal force of the classifier and the suction force of the blower, the separation of coarse and fine powders is achieved. Coarse powder returns to the pulverization chamber to continue pulverization due to its own gravity. Qualified fine powder enters the cyclone collector with the airflow, fine dust is collected by the bag dust collector, and the purified gas is discharged by the induced draft fan.
Performance Advantages and Features
Based on the design of traditional fluidized bed pulverizers, combined with our company's unique self-flowing classification technology, its performance is far superior to domestic and foreign fluidized bed air flow pulverizers.
1. Low energy consumption, compared with traditional fluidized bed air flow pulverizers, energy saving can be 30%.
2. Built-in self-flowing micro-powder classifier, concentrated particle size distribution, no oversized particles in the finished product.
3. Compact equipment structure, small footprint.
4. No material residue in the pulverization chamber, no dead corners, easy to disassemble, clean, disinfect, convenient to change varieties, and meet GMP requirements.
5. Low-temperature, medium-free pulverization, especially suitable for pulverization of low-melting-point, heat-sensitive, sugar-containing, and volatile materials.
6. For flammable and explosive materials, inert gas can be used as a medium to achieve fully enclosed pulverization. Inert gas is recycled with very low consumption.
7. Wide range of pulverization particle size, the finished product particle size can be adjusted in the range of 3～180um; a full range of models are available, with output ranging from 5～3000kg/h.
8. Negative pressure production, no dust pollution, excellent environment.
9. High degree of automation, strong stability, and easy operation.
