Grinding Steel Balls for Silver Ore Mine
Jiangyin Dongbang Steel Ball Machinery Co., Ltd., based in Jiangyin, Jiangsu, China, manufactures grinding steel balls specifically for silver ore milling. The balls are cast from high chrome alloy steel containing 10‑18 % chromium and are offered in diameters from 25 mm up to 125 mm, covering the most common size increments used in SAG and ball mills. Each ball meets the supplier’s stated surface hardness of 62‑64 HRC and core hardness of 61‑64 HRC.
The media are produced by hot‑rolling for sizes up to 100 mm and by forging for the 100‑125 mm range, a process that yields a uniform tempered martensite micro‑structure and a hardness tolerance of ±2 HRC. Impact toughness values reported by the supplier range from 14 J / cm² for 70 mm balls to 26 J / cm² for the 125 mm size, which aligns with typical performance of high‑chrome grinding media. ISO 9001, ISO 14001 and OHSAS 18001 certifications are listed, indicating compliance with international quality and environmental standards.
These balls are intended for intensive wet or dry grinding circuits in silver, gold and copper mines and are favoured by operators seeking to lower per‑ton ore processing costs while maintaining high throughput. The supplier states a minimum order of 100 tons per ball size, packs the product in 1 000 kg plastic bulk bags and accepts TT or LC payment terms. Delivery dates are negotiable, and buyers are encouraged to confirm incoterms and lead‑time details directly with the factory.

Sourcing Grinding Steel Balls for Silver Ore Mine from Jiangyin Dongbang Steel Ball Machinery Co., Ltd. - China Import Guide
Before placing an order, verify the steel grade, chromium content and the hardness certification supplied by Jiangyin Dongbang. Request the latest mill test report and a sample batch inspection report to confirm that the surface and core hardness values fall within the 62‑64 HRC and 61‑64 HRC ranges. Confirm the minimum order quantity of 100 tons per size and ensure the supplier can meet any custom size requirements you may have.
Discuss logistics early: the balls are shipped in 1 000 kg plastic bulk bags and can be delivered under FOB, CIF or DDP terms as agreed. Ask the supplier to specify the expected lead time for the chosen size range and to confirm the incoterm that best fits your freight strategy. Payment is usually made by TT or LC, so align the payment schedule with your credit terms before finalising the contract.
Plan for quality assurance on arrival. Arrange for a third‑party inspection to verify hardness, impact toughness and dimensional tolerance (typically ±0.5 mm) against the supplier’s test reports. Request the original ISO certificates and any additional material test certificates. Proper documentation, including a certificate of compliance and a packing list, will smooth customs clearance and help maintain consistent grinding performance.
