AT OGM MINING SUPPLIES, we manufacture our tamping’s in-house at our facility in Vereeniging, ensuring full control over quality, consistency and mineral content.
Our manufacturing services include:
- Locally produced tamping’s (OGM Caps & Kgwahla) using metallurgical-grade graded sinter dolomite and ECCA bentonite.
- Low-silica formulations developed with input and verification from Mintek, keeping total crystalline silica content below 5% by mass.
- Crushed and screened dolomite chips carefully graded for optimal blast-hole wedging and gas confinement.
- Strict quality checks using industry-recommended analytical methods to ensure mineral composition and product performance remain consistent.
This service ensures mines receive reliable, repeatable tamping products that support safe, efficient and compliant underground blasting.
