Zirconia Ball Mill Jar
Product Details
Product Introduction:
Zirconia Ball Mill Jar Good restitance and high strength, while testing rare earth material, it can ensure the abraded material is not mixed with other impurities. Pure zirconia is a high refractory material, while the melting temperature achieved 2900°C it improves the high temperature viscosity of the glaze and expanded temperature range of viscosity, has good thermal stability.

Compared with steel ball, ceramic ball has following advantages:
| 1. | 59% lighter than steel ball, which means less centrifugal force and less wear on the groove during high speed and acceleration. |
2. 44% larger elastic modulus, which means less deformation under load.
3. Harder with Rockwell hardness as 78.
4. Smaller friction coefficient.
5. Only 1/4 coefficient of thermal expansion of steel, can endure sharp fluctuation of temperature.
6. Superior surface finish can be achieved, Ra could be 0.2-0.8 for outter surface.
