Introduction Dry ultra-fine grinding technology has become the mainstream processing solution for mineral powder, chemical raw materials, pharmaceutical excipients, ceramic fillers and new energy materials. Unlike wet grinding that relies on water or solvent medium, the whole dry milling system completes crushing, dispersion and classification under anhydrous conditions. It perfectly…

In industries such as lithium battery cathode materials, electronic-grade fillers, pharmaceutical fine powders, and high-end coatings, a single jet mill or single-stage classifier is increasingly unable to meet strict requirements such as D97 ≤ 3 μm, narrow particle size distribution, and zero tolerance for oversize particles. A multi-stage air classifier…

In the modern pharmaceutical industry, GMP (Good Manufacturing Practice) certification has become a necessary threshold for enterprises to enter the global market. From raw material processing to finished product production, every link must meet strict standards of cleanliness, traceability, stability and safety. As key equipment for powder refinement, ultra-fine grinders…

In the field of chemical powder processing, ultra-fine grinding equipment is key to determining particle size, purity, and production continuity. Chemical raw materials often exhibit acidity, alkalinity, oxidizability, hygroscopicity, flammability, and explosiveness. Ordinary equipment easily suffers from corrosion, rust, leakage, short service life, and poor stability. Therefore, corrosion resistance and…

As a typical heat-sensitive bioactive material, enzyme preparations are widely used in feed, food, pharmaceutical, chemical and other industries. The traditional grinding process tends to cause reduced enzyme activity and denaturation due to frictional heat generation, which has become a common pain point in the industry. Cryogenic ultra-fine grinding technology,…
