Grinding steel ball

The grinding steel balls offered by Zhangqiu Donghan Artistic Iron Co., Ltd. are forged from high carbon steel. They are supplied in diameters from 20 mm up to 150 mm, covering most grinding circuit requirements. The material is heat‑treated to achieve a hardness of 60 - 65 HRC, which provides wear resistance in abrasive environments. Both ISO and SGS certifications are listed for the production process.

In the grinding media market, such balls are commonly supplied with a diameter tolerance of ±0.05 mm, a standard that ensures consistent mill performance. Typical surface roughness for these media is Ra 0.2 µm, helping to minimise energy loss during operation. The density of high carbon steel is about 7.85 g cm‑3, a value used by engineers to calculate mill charge volume. Suppliers often package the balls in bulk bags or bulk containers, a practice that reduces handling costs.

These balls find use in ore grinding, cement clinker production and mineral processing where reliable impact resistance reduces downtime. Zhangqiu Donghan Artistic Iron Co., Ltd. states that shipments can be arranged on FOB or CIF terms, with payment by L/C or T/T. Buyers should confirm the exact MOQ and packaging details directly with the supplier before placing an order.

Zhangqiu Donghan Artistic Iron Co., Ltd. is located in the Huamin Exporting Industry Zone, Zhangqiu, Shandong, China. The company is classified as an imported‑tier supplier with a harbor trust tier, indicating that it has passed basic verification for overseas trade. Its official address is 250217 Shandong, China, which places it within a recognised industrial cluster for metal manufacturing. The listing does not provide a response rate or average response time, so buyers should request communication timelines directly.

The firm specialises in producing grinding media such as steel balls for a variety of heavy‑industry applications. While the source description highlights bulk supply capability, no specific minimum order quantity is disclosed in the public data. Prospective importers can expect standard payment methods like L/C and T/T, as noted in the trade information. Any additional certifications beyond ISO and SGS would need to be verified with the supplier.
