The cast grinding steel ball is a wear‑resistant media produced from high chrome alloy cast steel. It is offered in diameters from 10 mm to 150 mm, with a surface hardness measured between 58 and 66 HRC. The balls exhibit an impact resistance of approximately 3.5 J cm‑2 and a breakage rate below 1 % under normal milling conditions. Production follows ISO 9001:2008 procedures, ensuring dimensional consistency for high‑volume mineral processing and cement grinding operations.
High chrome alloy provides superior abrasion resistance compared with plain carbon steel, a common requirement in ball‑mill circuits that operate continuously. In the grinding‑media market, standard grades such as AISI 52100 or equivalent alloy are used for similar applications, delivering a typical density of 7.85 g cm‑3 and a tolerance of ±0.02 mm on the nominal diameter. The heat‑treatment process employed by Chengxi yields a surface roughness around Ra 0.4 µm, which is within the typical range for efficient slurry flow. These characteristics align with the expectations of OEMs and plant engineers who prioritize low wear rates and consistent grinding efficiency.
The balls are employed in ball mills for mineral extraction, cement clinker production and power‑plant coal grinding, where reliable media reduces downtime and improves product fineness. Primary buyers include mining contractors, cement manufacturers and large‑scale power generators who source media in bulk quantities. While the listing does not disclose minimum order quantities or delivery timelines, interested parties should request bulk pricing, Incoterms and payment conditions directly from Chengxi to complete the transaction.

Before placing an order, buyers should verify the exact diameter range, surface hardness, impact energy and breakage rate against the specifications provided. Request the latest ISO 9001:2008 certificate and a recent mill‑test report to confirm that the material composition and heat‑treatment process meet your project requirements. Confirm that the packaging dimensions and weight per unit are suitable for your handling equipment.
Logistics for bulk steel media typically involve sea freight from ports such as Shanghai or Ningbo. Although the listing does not state a lead time, purchasers should ask Chengxi for estimated production lead time, preferred Incoterms (e.g., FOB, CIF) and any freight forwarder recommendations. Payment terms are not disclosed; clarify whether a letter of credit, telegraphic transfer or other method is acceptable before finalising the contract.
Quality assurance usually includes visual inspection for surface defects, hardness testing and impact‑energy verification. Arrange for a pre‑shipment inspection by a recognised third‑party agency if required, and request the test certificates for hardness and impact resistance. Ensure that the shipment is accompanied by a full material safety data sheet, a certificate of conformity and the ISO 9001:2008 audit report.
