Import Forged Grinding Steel Ball — Buy in Bulk from Supplier in China

Shandong Huamin Steel Ball Joint-stock Co., Ltd. offers forged grinding steel balls that are engineered for high‑energy milling operations across heavy‑industry sectors. The product range covers diameters from 20 mm up to 150 mm, delivering a consistent hardness profile that supports efficient ore breakage. Each ball is manufactured by a high‑temperature forging process that eliminates internal porosity and improves impact strength. The company operates from Yangjun Village, Guanzhuang Town, Zhangqiu, Jinan, Shandong Province, China.

The steel used conforms to the typical AISI 8620 carbon‑alloy specification, achieving a Rockwell C hardness of 62 - 65 HRC and a surface roughness of Ra 0.2 µm. Dimensional tolerance is generally held within ±0.025 mm, and the forged microstructure provides an impact energy rating of approximately 150 J, which is favourable for demanding grinding circuits. With a declared annual production capacity of 100,000 tons, the supplier can accommodate large‑scale orders while also offering custom alloy adjustments on request. These technical characteristics meet the common standards for grinding media used in mineral, cement and chemical processing plants.

The balls are suitable for both wet and dry ball‑mill applications in mining, cement clinker grinding and chemical material reduction. Trade terms include flexible minimum order quantities and payment options of L/C or T/T, with shipping arrangements possible on FOB or CIF basis. The supplier states compliance with ISO and SGS quality systems; buyers should request the latest certificates to confirm. Because lead time details are not disclosed, it is advisable to obtain a production schedule from the supplier before finalising the contract.
