It is especially suitable for vertical stirring mills, horizontal rolling ball mills, vibration mills and various rod-pin sand mills with high linear speed. Finely dispersed and ground. The application areas are as follows:
1. Wear-resistant and corrosion-resistant products: coatings, textiles, pigments, printing and dyeing.
2. High-strength, high-toughness products: magnetic materials, piezoelectric ceramics, dielectric ceramics.
3. Prevent pollution: medicine, food, cosmetics.
4. Ceramics: electronic ceramics, refractory ceramics, structural ceramics.
