Grinding Balls Supply in South Africa

Songatech is a premier supplier of high-performance Grinding Balls, providing both cast and forged media engineered to resist wear and breakage in high-impact milling environments. Our grinding media is designed to ensure a steady grind, controlled make-up rates, and reliable power draw, helping you maintain a predictable cost per tonne. On this page, we explain our grinding media range and our capacity to supply mining operations across South Africa.

Comprehensive Grinding Media Catalogue

The performance of your mill depends on the hardness profile, impact toughness, and size control of the media. From our strategic base in Alrode, Alberton, we distribute these critical consumables to major mining hubs in Rustenburg, Kathu, Postmasburg, and Middelburg:

Forged Steel Grinding Balls: Recommended for primary and SAG (Semi-Autogenous Grinding) milling where impact toughness is critical. These are produced from clean steel and heat-treated to achieve target hardness across the entire cross-section.
Cast Steel Grinding Balls (High and Low Chrome): The best choice for secondary grinding, regrind circuits, and cement plants. High Chrome options provide exceptional abrasion resistance, especially in corrosive pulps or when processing very hard ores.

Quality Assurance and Plant Support

At Songatech, we don’t just supply media; we provide the quality assurance and technical support needed to stabilise your mill operations.

Through-Hardness: Every batch is checked for consistent core hardness to ensure the ball maintains its shape and impact resistance as it wears.
Dimensional Control: We perform rigorous roundness and size checks to prevent mill instability and irregular power draw.
Traceability: All batches are supplied with QA reports, including heat treatment curves and hardness readings from surface to core.
Mill Trial Support: Our team assists with monthly wear tracking and mill trial support to help you optimise your media charge and top-up rates.

Selection Guide for South African Mills

Choosing the correct media depends on your mill type and the abrasiveness of your ore:

Primary / SAG Milling (High Impact): We recommend Forged Steel Balls (100 to 125 mm) to handle coarse feed and high impact energy. Focus on toughness and stable power draw.
Secondary Milling (Mixed Impact/Abrasion): A transitional duty where both wear and impact matter. We recommend Forged 80 to 100 mm or Cast 60 to 90 mm, matched to your specific liner profile.
Regrind / Fine Grinding (High Abrasion): For fine grinds where abrasion is dominant, Cast High Chrome balls (20 to 60 mm) provide the necessary surface hardness for wear control.
Cement (Dry Grinding): We supply Cast Low or High Chrome (20 to 90 mm) depending on clinker hardness and mill layout.
