An Italian ceramics firm sought to improve the efficiency of their glaze grinding process while reducing wear on milling equipment. Traditional zirconia balls showed low fracture toughness in abrasive slurries, leading to frequent ball breakage and contamination risks.
Kegu developed pressureless sintered silicon carbide (SSiC) grinding media solutions optimized for abrasive ceramic and chemical processing environments, featuring:
- grading optimization with dominant particle sizes of 10–11 mm for improved impact efficiency,
- surface hardness up to 2800 HV,
- and electrically insulating properties suitable for sensitive electronic glaze formulations.
Using SSiC grinding media components, grinding efficiency improved by 45%, reducing processing time from 8 hours to 4.5 hours per batch.
Ball wear rate decreased from 0.3%/cycle to 0.08%/cycle, significantly lowering replacement frequency and contamination risk.
Pressureless sintered silicon carbide (SSiC) grinding media are widely used in:
- ceramic processing,
- mining,
- chemical milling,
- and high-purity grinding applications.
Typical advantages include:
- high hardness,
- low wear rate,
- contamination control,
- and long service life.
