The JFC series jet milling and classification equipment is developed with technical support from the Beijing Key Laboratory of Powder Technology Research and Development at Beihang University. Leveraging the company's profound expertise in fluid mechanics, the equipment is designed and manufactured based on the principles of gas dynamics and multiphase flow theory, making it a leading ultra-fine powder production device both domestically and internationally. Its key technologies have been granted four national patents and won the Gold Award at the "China's Top Ten Achievements Exhibition" in 1995. In 1996, it was included in the National Science and Technology Commission's "Ninth Five-Year Plan Key Promotion Program for Major Scientific and Technological Achievements." In 2000, it was recognized as a "National Key New Product" by five national ministries and commissions. Long-term research and practice have demonstrated that the ultra-fine powder produced by JFC equipment surpasses the quality of similar products both domestically and internationally.

Working principle
Dry, oil-free compressed air is accelerated into a supersonic airflow, which carries materials at high speed, causing them to collide and rub against each other until they are pulverized. Materials that meet the particle size requirements pass through a classifier and are collected by a collector, while those that do not meet the requirements are returned by the classifier to the crushing chamber for further pulverization. The entire process operates continuously in a fully enclosed system, with no dust pollution and low noise. For easily oxidizable materials, inert gas can be used for crushing and classification.

Characteristics
Fine particle size, with an average particle size reaching 0.5 μm and a D97 particle size reaching 3-5 μm.
Narrow particle size distribution, already applied in abrasives, NdFeB, lithium cobalt oxide for lithium batteries, and battery carbon powder.
The airflow and materials enter the crushing chamber through separate paths, where the materials collide with each other to achieve crushing. As a result, the nozzle and crushing chamber experience minimal wear, and the finished product has high purity. It can crush materials with a Mohs hardness of 1 to 10.
Special flow field control enables higher crushing efficiency and greater output.
Advanced hierarchical structure and flow field control enable the particle size and distribution of the powder to reach world-class **.
The product particle size is continuously adjustable, the equipment is simple to operate, and it is stable and reliable for long-term continuous operation.
The temperature of supersonic jet gas is far lower than room temperature, so it can crush heat-sensitive materials and the like.
