1. Working Principle
Compressed air, after cooling, filtration, and drying, forms a supersonic airflow through a nozzle and is injected into a rotating grinding chamber, fluidizing the material. Inside the rotating grinding chamber, the accelerated material converges at the intersection points of several nozzles, resulting in intense collisions, friction, and shear, achieving ultra-fine grinding of the particles. The ground material is transported by the rising airflow to the impeller classification zone, where, under the combined action of the centrifugal force of the classifier wheel and the suction force of the fan, coarse and fine powders are separated. Fine powder meeting the upper limit of particle size requirements enters the main classifier with the airflow. In the impeller classification zone, powder that meets the product requirements is collected through the discharge port of the classifier. Micro-fine powder finer than the required particle size is carried by the airflow into a cyclone collector and a bag filter for collection, while the purified gas is discharged by an induced draft fan.
II. Performance Advantages and Features
The cyclone-type jet mill is a new type of jet mill independently developed by Henan Fuland Heavy Industry Machinery Co., Ltd. Its introduction addresses the shortcomings of high energy consumption and low output in jet mills. It serves as a next-generation product replacing opposed-jet and fluidized-bed jet mills, with technical performance fully surpassing similar products both domestically and internationally.
1. With the same energy consumption, the crushing output is doubled compared to that of jet and fluidized bed air jet mills.
2. It can be configured with 1 to 4 classifiers in series, enabling the simultaneous production of multiple products with narrow particle size distributions.
3. When producing products with a narrow particle size distribution, the yield rate is more than double that of traditional opposed-jet and fluidized-bed jet mills.
4. Multi-purpose machine: It can be used as a standalone crusher or as a standalone classifier.
5. Configure an automatic flow classification system, resulting in a narrow particle size distribution of the product. The service life of the classification wheel is 5 to 8 times longer than that of horizontal or vertical classification wheels.
6. Wide feed particle size range, with a **feed particle size of up to 5mm**.
7. It is not only used for ultra-fine grinding but also has the functions of particle shaping and particle dispersion.
8. For flammable, explosive, or easily oxidized materials, inert gas can be used as a medium to achieve closed-circuit crushing, with the inert gas being recycled, resulting in extremely low losses.
9. Low-temperature, media-free grinding, particularly suitable for ultra-fine grinding of low-melting-point and heat-sensitive materials.
10. Minimal wear, making it especially suitable for ultra-fine grinding of materials with high hardness and high purity.
11. The equipment has a compact structure, with polished inner and outer walls. The crushing chamber has no material accumulation, no dead corners, is easy to clean, and meets GMP requirements.
12. Negative pressure production ensures no dust pollution and an excellent working environment.
13. Automatic control, simple operation, and stable operation.
