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

The Forged & Casted Grinding Steel Ball offered by Shandong Iraeta Heavy Industry Stock Co., Ltd. is produced in China for use in milling circuits. The balls are manufactured from high‑carbon alloy steel and undergo a proprietary heat‑treatment cycle that yields a hardness of around 60 HRC. The supplier states that the balls are available in a range of diameters that can be matched to the buyer’s grinding mill specifications. International certifications such as ISO 9001 and SGS are mentioned in the product listing.

In the grinding‑media market, bearing‑grade steel (AISI 52100) is the standard material because of its wear resistance and compressive strength. Typical grinding balls of this class are supplied with a surface roughness of Ra ≤ 0.2 µm and a dimensional tolerance of ±0.02 mm, which ensures consistent mill load distribution. The heat‑treated balls from this supplier are designed to sustain prolonged operation in mining, cement and chemical grinding lines, reducing downtime caused by premature wear. Their bulk packaging is engineered to protect the balls from moisture and impact during sea transport.

Primary users include mining contractors, cement plant operators and large‑scale chemical manufacturers who require reliable media for size reduction. The listing notes that the supplier can ship on FOB or CIF terms and accepts payment by T/T or L/C, but exact minimum order quantities and lead times are not disclosed and should be confirmed directly. Buyers are advised to request the latest material test report and certification copies before finalising the contract. The combination of a proven heat‑treatment process and certified quality control makes these balls a practical choice for high‑throughput grinding operations.

Shandong Iraeta Heavy Industry Stock Co., Ltd. is located at No.9001 Jiwang Road, Zhangqiu, Jinan, Shandong, China. The company is classified as an imported‑tier supplier and carries a harbour‑level trust tier, although its current response rate on the platform is recorded as 0 % with no average response time data available. The listed address and tier information are the only verifiable details provided about the firm’s operational standing.

The supplier’s product offering focuses on forged and cast grinding steel balls that are heat‑treated and quality‑checked against international standards. The listing mentions ISO and SGS certifications, as well as packaging designed for secure transport, but it does not disclose minimum order quantities, unit pricing or specific lead‑time commitments. Prospective buyers should therefore seek clarification on these commercial terms directly from the supplier.
