Levigated China Clay for Advanced Ceramic Production
Levigated china clay is produced through a specialized wet processing method where raw kaolin is mixed with water to create a slurry, then processed through de-gritting, solid-liquid separation, filtering, and drying stages. This purification process removes impurities and enhances physical properties such as brightness, whiteness, and post-firing.
- Enhanced Purity
- Superior Whiteness
- Consistent Quality
- Balanced Particle Size
Why Choose Expolica as
Levigated China Clay Manufacturer
Expolica Ceramics produces ultra-refined levigated china clay through advanced wet processing at our five mining facilities. Our multi-stage purification delivers exceptional whiteness, purity, and particle consistency for premium ceramic applications across India.
- Advanced Wet Processing : Our processing plants feature modern levigation equipment including hydro-cyclones, centrifugal separators, and filtration systems. This infrastructure removes coarse particles, organic matter, and metallic impurities efficiently.
- Brightness Levels Above 92% : Through careful impurity removal and mineral separation, our levigated china clay achieves brightness readings consistently above 92%. This exceptional whiteness reduces your need for additional whitening agents in ceramic formulations.
- Narrow Particle Size Distribution: Our classification systems produce levigated clay with tightly controlled particle ranges. This narrow distribution improves slip casting behavior, reduces settling issues, and enhances green strength in formed pieces.
- Moisture-Controlled Packaging: We offer levigated china clay in filter cake form (20-25% moisture), powder form (8-10% moisture), or completely dried. Choose the format matching your mixing equipment and process requirements.
- Application-Specific Processing: Different ceramic applications need different clay properties. For tile manufacturing, we optimize for suspension stability. For sanitaryware, we focus on casting rate
- Traceability from Mine to Dispatch: Every batch receives a unique identification code linking it to the specific mine, processing date, and quality test results. This traceability helps you maintain consistent formulations and quickly identify causes if production issues arise.
