Detailed introduction of ultrafine crusher

The airflow pulverizer, cyclone separator, dust collector, induced draft fan, etc. form a complete set of airflow pulverization system. It is a crushing system that utilizes multiple high-speed compressed gas vortices to repeatedly collide, rub, and shear materials in the crushing chamber. The entire crushing process has no temperature rise, no pollution, and minimal wear, making it suitable for ultrafine crushing of heat sensitive, low melting point, and volatile materials. Inert gas can be used instead of compressed air to achieve closed-loop crushing of flammable and explosive materials. Widely used for ultrafine grinding of dry powder materials in industries such as food, medicine, chemical, and new energy battery materials.

working principle

The negative pressure generated by the high-speed jet of compressed air (inert gas) through the feeding injector causes the powder raw material to be sucked into the crushing chamber, and through nozzles distributed on the same plane at a certain angle to the radius direction of the crushing chamber, multiple high-speed airflows with a speed of several Mach are generated. The material particles are repeatedly collided, rubbed, and sheared at the intersection of high-speed airflow, resulting in the pulverization of micro - or sub micron sized ultrafine particles. The high-speed jet forms a strong vortex inside the crushing chamber, generating strong centrifugal force. The crushed material is separated into coarse and fine materials under the action of centrifugal force. Fine particles that meet the particle size requirements enter the cyclone separator and collector through the classification zone for collection, while coarse particles return to the crushing zone for further crushing.

Performance Characteristics

1. During the crushing process, the airflow rapidly expands and the temperature decreases, making it particularly suitable for crushing heat sensitive, low melting point, and volatile materials.

2. Suitable for dry crushing of various materials, especially for crushing materials with high hardness, high purity, and high added value.

3. Materials collide with each other and self grind, resulting in minimal equipment wear and high product purity.

4. Can be used in series with multi-stage classifiers to produce products in multiple particle size ranges at once.

5. High crushing efficiency, low energy consumption, and good particle shape after crushing.

6. The device has a compact structure, easy disassembly and cleaning, and smooth inner walls without dead corners.

7. The entire system is sealed and crushed, with no dust, low noise, and a clean and environmentally friendly production process.

8. The control system adopts PLC automatic control, which is easy to operate.
