Product lineups :
1: Polished Silicon Nitride Grinding Balls
 *Initial wear avoidable.
2: Unpolished Silicon Nitride Grinding Balls (ball blanks as grinding media)

Our business :
We handle the entire production process in-house, from procuring and grinding silicon nitride powder to granulation, sintering, inspection, and shipping.

Feature :
Our non-oxide ceramics, Si3N4, balls with high strength realize excellent grinding efficiency compared to alumina and zirconia balls. They are suitable for coarse grinding of high-strength non-oxide ceramics, fine grinding of high-strength non-oxide ceramics, glass frit fine grinding in the semiconductor field, fine grinding of additives, and etc. Additionally, they perform well under mild grinding conditions and allow for dispersion. They also have superior wear resistance as grinding balls themselves compared to alumina and zirconia balls. They are also useful for contamination-conscious grinding.

Physical Properties Table :

Note : The figures here are reference values.

Sphere equivalent diameter :

We can consider and develop new balls along with your diameter request.

Benefit of Ellipsoid shape :

Given the presence of both spherical points and linear contact points when grinding the material to be crushed, it is believed that the number of collision surfaces increases compared to mere spherical grinding media, resulting in improved grinding efficiency.

Particle size and particle-size distribution per diameter of grinding ball :

Ware rate comparison of grinding ball between ceramics types :

Compared to another supplier's Zirconia and Alumina grinding balls, it is believed that the wear rate due to grinding balls is lower for the characteristics of our Silicon Nitride grinding balls, resulting in reduced contamination caused by wear of the grinding balls.

Lead-time :
