Import Grinding Steel Ball / Grinding Media For Mining — Buy in wholesale FOB from Supplier in China

The grinding media offered by Shandong Iraeta Heavy Industry Stock Co., Ltd. are forged steel balls intended for mining operations in China. Surface hardness is reported between HRC 57 and HRC 67, while volume hardness lies between HRC 56 and HRC 64. Impact toughness exceeds 12 J / cm² and the observed broken rate does not surpass 1 %. The balls are supplied in diameters that the listing does not enumerate, so buyers should request the size range that matches their mill.

The alloy is produced from audited steel‑mill raw material and undergoes a special heat‑treatment cycle that typically yields a hardness of about 45‑55 HRC for comparable media, indicating a range of treatment options. Such hardness levels are standard for high‑wear grinding media and align with industry expectations for SAG and ball‑mill applications. Typical wear rate for this class of media is around 0.02 % per 100 h, and the low broken‑rate claim reflects good internal stress relief after quenching and tempering. The joint‑venture’s academician workstation with the Shenyang Metal Institution of CAS enables custom alloy adjustments for specific mine conditions, a practice common among premium grinding‑media suppliers.

End users include mining companies, cement producers and large‑scale power‑generation plants that require reliable media to reduce operating costs. The supplier mentions that more than 20 global top‑500 enterprises purchase its forgings, suggesting suitability for high‑volume industrial users. Trade conditions such as incoterms, lead time and payment method are not detailed in the listing; prospective buyers should verify CIF or FOB options and acceptable payment terms directly. Because the response rate is listed as 0 % and average response hours are zero, contacting the supplier to confirm capacity and delivery schedule is advisable.

Shandong Iraeta Heavy Industry Stock Co., Ltd. is located at No.9001 Jiwang Road, Zhangqiu, Jinan, Shandong, China, postal code 250200. The company operates as a Sino‑Spanish joint venture, with Gestamp Group listed among its shareholders, and holds a harbor trust tier on the platform, confirming verified business status. The listed response rate is 0 % and average response time is not recorded, so communication may require persistent follow‑up.

Since its founding in 1975, Iraeta has accumulated more than 20 international and industrial certifications and has contributed to the drafting of two national industrial standards. The firm sources raw steel only from audited mills and runs a dedicated academician workstation in partnership with the Shenyang Metal Institution of CAS, enabling customized alloy formulations. Its heat‑treatment processes deliver low wear rates and high toughness, supporting customers in mining, shipbuilding, petrochemical, wind‑power and other heavy‑industry sectors.
