Alumina Ceramic Grinding Balls are also known as wear-resistant ceramic balls, high-alumina balls, alumina balls, etc.
Suitable equipment: grinding media for various equipment such as ball mills, stirred mills, flaking machines, polishing machines and sand mills (sand mills).
Product features: low wear, high hardness, corrosion resistance, impact resistance, economical and practical.
1. High grinding performance: scientifically formulated wear-resistant ceramic balls have 2-5 times higher wear resistance than general materials.
2. Good fluidity: thanks to the advanced preparation process, the surface of the ball is smooth, the self-lubricating performance of the ceramic is outstanding, the scientific sorting process ensures the optimal roundness, and the wear is low in grinding conditions.
3. Impact and wear resistance: toughened ceramics have good toughness at high temperatures and can easily cope with it even when used in equipment with high working intensity.
