Ultra-fine impact mills are developed based on the characteristics of various mechanical mills at home and abroad, combined with the company’s years of experience in powder engineering. They integrate a unique crushing mechanism and grading technology, offering ultra-fine crushing, dispersion, and shaping. Inert gas can be used as a protective medium to enable closed-loop production of flammable, explosive, and easily oxidizable ultra-low moisture materials. The non-metallic lining provides full protection, ensuring ultra-pure production of new energy and electronic materials.
