Description
Zirconia Ball Grinding Media is made of good material. It uses advanced technology, suitable for any kind of mill such as a sand mill, attrition mill, vibratory mill, ball mill, and so on. It is used to grind and disperse the painting material, dye, ink, titanium, electronic battery material, rare-earth material, nonmetal ore, calcium, and food, etc.Because of its high density, toughness, and hardness, zirconium grinding media’s efficiency is much better than traditional ones. The high wear-resistant zirconium grinding media can not only prevent materials from being contaminated but also prevent chemical erosion that affects its working life
Features:
1. Good roundness, smooth surface, brightness, high density, high strength inertia, and hardness, perfect
grinding medium.
2. With a very low wear rate, grinding media can prevent the material from.
3. Very long service life which can decrease its comprehensive operating cost.
4. Good stability, strong acid resistance, and alkali proof.
