Disc jet mill

Product Advantages

1. Suitable for dry grinding of various materials with a Mohs hardness of 7 or less, especially for high-hardness, high-purity, and high-value-added materials.
2. Product particle size (D50): Adjustable between 1.5 and 45 microns, with excellent particle shape and narrow particle size distribution, suitable for dispersing agglomerates.
3. Low-temperature, media-free grinding, especially suitable for grinding heat-sensitive, low-melting-point, sugar-containing, and volatile materials.
4. The entire system is enclosed, and the grinding process is achieved through collision between the materials themselves, unlike mechanical grinding, which relies on The material is crushed by the impact of blades or hammers, making the equipment wear-resistant and producing high-purity products.
5. No dead spots, no risk of material backlog, easy explosion-proof verification, no safety hazards, extremely simple cleaning, and convenient disassembly and replacement of accessories.
6. No transmission parts, a self-grading structure, and a large number of nozzles ensure high crushing efficiency.
7. An explosion-proof design is available, and it can be upgraded to a nitrogen circulation system to meet the ultrafine crushing needs of flammable, explosive, and oxidizable materials.
8. The control system is programmable for easy operation.

Working Principle

The airflow mill, along with a cyclone separator, dust collector, and induced draft fan, forms a complete pulverizing system. After being cooled, filtered, and dried, compressed air is injected at high speed into the pulverizing chamber through multiple Laval nozzles. At the intersection of these multiple high-pressure airflows, the material is repeatedly pulverized by collision, friction, and shearing. The pulverized material follows the rising airflow through the high-speed rotating classifying wheel, where centrifugal and centripetal forces separate the coarse and fine materials. Fine particles that meet the required particle size pass through the grading zone and are collected in the cyclone separator and dust collector, while the coarse particles return to the pulverizing zone for further pulverization.
