Introduction of Silicon Carbide Grinding Balls

Silicon Carbide Grinding Balls are high-performance ceramic grinding media made from Silicon Carbide (SiC) with high hardness, high density, and excellent wear resistance. Silicon carbide is an advanced engineering ceramic material known for its high hardness, high thermal conductivity, and chemical stability. Silicon Carbide Grinding Balls are widely used in powder grinding, dispersing, and mixing processes and are ideal for efficient grinding and fine processing.

Features of Silicon Carbide Grinding Balls

High hardness and wear resistance: The high hardness of silicon carbide, second only to diamond and cubic boron nitride, can effectively resist wear and prolong service life.

High density: The density is usually 3.1-3.2 g/cm³, providing higher impact energy and improving grinding efficiency.

Chemical Stability: Extremely resistant to acids, alkalis, and organic solvents, suitable for a wide range of chemical environments.

Low contamination: virtually no impurities are introduced during the grinding process, ensuring high purity of the powder.

Excellent impact resistance: high toughness, able to withstand high-speed impact without breaking.

Smooth surface: after precision processing, the surface is smooth, reducing the wear and tear on the grinding equipment.

High temperature resistance: able to maintain stable performance in high temperature environment, suitable for high temperature grinding process.
