Silicon Nitride Grinding Ball Features:
1. High hardness, goodresistance, and long service life
2. High temperature resistance, maintaining high strength and hardness even at a high temperature of 1200℃
3. Low density and high densification
4. Self-lubricating never rusting
5. Low coefficient of themal expansion, high thermal shock resistance
6. Anticorrosion of acid and alk
7. Nonmagnetic and electrical insulation
8. At high temperatures, it does not adhere to the metal and hardly reacts
Silicon Nitride Grinding Ball Application:
1. Equipment such as ball mills, stirring mills, and vibration mills used in laboratories and production lines.
2. Fields such as crushing, grinding, or dispersing advanced ceramic powder materials, magnetic materials, non-metallic mineral materials, and pyrotechnic materials.
3. Ultra fine dispersion of high-end materials, especially in working conditions with extremelyhigh requirements for product purity and fineness.
