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

Shandong Huamin Steel Ball Joint-Stock Co., Ltd manufactures grinding steel balls ranging from 20 mm to 150 mm in diameter, with an annual production capacity of up to 50 000 tonnes. The balls are forged from high‑grade steel and are noted for exceptional hardness, which supports long‑lasting performance in demanding grinding environments. The supplier cites ISO and SGS certifications as part of its quality management system, although the specific certificate numbers are not disclosed in the listing. These attributes position the balls for use in large‑scale grinding mills across several industries.

Typical steel grinding balls of this size are produced to a hardness of 58‑62 HRC and conform to the ASTM A1037 standard for steel shot and grit. Chemical composition commonly includes 0.9‑1.2 % carbon, 0.5‑0.8 % chromium and trace amounts of manganese and silicon, providing a balance of wear resistance and toughness; such composition is standard for high‑performance grinding media. Dimensional tolerance is usually ±0.02 mm for the stated diameters, and surface roughness is kept within Ra 0.2 µm to minimise wear on mill liners. The balls are supplied in bulk bags or wooden crates, with each crate containing a known quantity of balls for easy handling.

These grinding balls are employed in mining, cement and metallurgy sectors where efficient comminution is essential. Prospective importers should verify the exact hardness, chemical composition and certification status before confirming a purchase, as these factors influence mill performance and product lifespan. The listing does not specify minimum order quantities, lead times, Incoterms or payment conditions, so buyers must discuss these commercial details directly with Shandong Huamin. Aligning logistics, customs documentation and inspection plans with the supplier will streamline the sourcing process.

Shandong Huamin Steel Ball Joint-Stock Co., Ltd is located in Yangjun Village, Guanzhuang Town, Zhangqiu, Shandong Province, China, postal code 250217.
