Manufacturing Process of Silicon Carbide Grit: Step-By-Step Flow

1. Raw Material Selection → High-grade petroleum coke & fine quartz sand sourced and quality checked (SGS, ISO 8486 compliance).

2. High-Temperature Electric Arc Furnace Smelting → Mixture heated to 2000–2500°C, enabling SiC crystal formation via reductionreaction.

3. Crushing & Milling → Large SiC ingots mechanically crushed, then milled by ball-milling or vibro-milling for granularity control.

4. Magnetic Separation & Purification → Removes ferrous impurities to increase SiC purity above 98%.

5. Particle Classification (CNC/ISO Control) → CNC sieving per ISO 8486/ANSI B74, controlled D₅₀ size distribution for consistency.

6. Final Packaging & Quality Assurance Tested as per ISO/ANSI standards, stored in anti-static bags, ready for delivery.
