Zirconia grinding ballProduct Introduction:
Zirconia balls are also known as zirconia grinding balls or zirconia ceramic balls.Zirconia grinding balls have high purity and are processed using special molding techniques and surface treatment processes. The overall structure of microbeads is composed of uniform and dense zirconia microcrystals, which have good wear resistance and will not break the beads during high-speed operation. It is suitable as a ball milling medium for the development of various ball mill powders and can be used in situations where sample contamination is low, wear is low, and high viscosity is required. Zirconia grinding balls are widely used for grinding and dispersing in industries such as paint, ink, coatings, papermaking, electronic materials, solar cells, pharmaceuticals, non-metallic minerals, pigments, etc.
Zirconia grinding ballProduct features:
At room temperature, it has high strength and toughness, high density, good wear resistance, high temperature and corrosion resistance, high stiffness, non-magnetic, electrical insulation, and a thermal expansion coefficient close to that of steel. Advantages: The strength and hardness of zirconia ceramic balls remain almost unchanged at 600 ℃.
1. High grinding efficiency: Yttrium stabilized TZP zirconia ceramic microspheres have a specific gravity 1.6 times that of ordinary zirconia beads, and have higher grinding efficiency under the same conditions.
2. Good fluidity: The product has good roundness, smooth surface, and lower wear on equipment compared to other grinding media.
3. Impact resistance and low wear: TZP zirconia ceramic microspheres have good toughness and do not crack or peel off in high-speed and high concentration machines. The wear is only 1/2 of that of zirconia silicate beads.
4. Low cost of use: Choosing this product will definitely bring you a comprehensive cost reduction such as medium wear, electricity consumption, labor, equipment, etc., and significantly improve product quality.
