Abrasive Resistance Sic Spheres Silicon Carbide Ceramic Grinding Ball

Product Description

Product Description

 Silicon Carbide Milling Media

We produce sintered SiC balls, reaction bonded SiC balls and recrystallized SiC balls. Our recrystallized SiC products have a high purity, while our reaction bonded and sintered silicon carbide balls have a high mechanical strength. Our silicon carbide balls possess good wearability,a low thermal expansion coefficient, extreme corrosion resistance, high hardness and self-lubricating properties.

Mohs Hardness 9.5 — harder than alumina (9.0) and zirconia (8.5), second only to diamond
20% lighter than alumina balls → lower mill energy consumption
Wear rate: 1/5 of zirconia balls in high-speed sand mills
Fracture rate ≤ 0.2% under standard operating conditions
Excellent chemical resistance: resists acids (except HF) and alkalis
Non-magnetic, electrically conductive (unlike alumina)

Silicon Carbide Grinding Balls

Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent
thermal conductivity, low thermal expansion, and is resistant to corrosion from acids. Silicon carbide is an excellent ceramic
material for applications requiring good erosion and abrasive resistance.

Q2: Which size should I choose for my application?
A: 0.5–3mm for ultra-fine grinding (bead mills, sand mills, battery slurries); 5–10mm for standard ball mills; 15–50mm for coarse grinding and heavy-impact ore milling. Contact us with your mill type and material for a size recommendation.
