Forged Grinding Ball
Chengde Rongmao Cast Steel Co., Ltd. manufactures forged grinding balls from high‑carbon chromium forged steel. The balls are supplied in diameters from 100 mm to 125 mm, matching the dimensions required for large SAG mills. Each ball achieves a surface hardness of 58‑65 HRC with a core hardness tolerance not exceeding ±2 HRC. Impact toughness is reported above 12 J/cm² and the observed broken rate stays below 1 % in operation.
The high‑carbon chromium alloy provides a balanced combination of wear resistance and toughness that is recognised across mineral‑processing applications. Chemical analysis shows carbon between 0.52‑0.65 %, silicon up to 0.15 %, manganese 0.60‑1.20 %, chromium 0.20‑0.30 % and trace phosphorus and sulphur, a composition typical for forged grinding media. Compared with cast balls, forged balls deliver superior impact resistance and a more uniform hardness profile, which is standard practice for high‑value copper, gold and iron‑ore plants. The production line includes automated forging, controlled heat treatment and strict quality control to meet the stated specifications.
These balls are used primarily in SAG and AG mills for copper, gold and iron‑ore processing, where they improve grinding efficiency and product throughput. Mining contractors and mineral‑processing firms source the media in bulk, typically arranging shipment from ports such as Tianjin or Dalian under CIF or FOB terms. While the listing does not disclose minimum order quantities or exact pricing, buyers should confirm these details directly with Chengde Rongmao. Payment is usually made by T/T or L/C after verification of the mill test certificate, and lead times are negotiated per order size.

Sourcing Forged Grinding Ball from Chengde Rongmao Cast Steel Co., Ltd. - China Import Guide
Before placing an order, verify that the mill test certificate confirms the high‑carbon chromium composition, the 58‑65 HRC surface hardness and the ≤1 % broken‑rate claim. Request a detailed chemical analysis showing carbon, silicon, manganese, chromium, phosphorus and sulphur levels, as these affect wear performance. Confirm the exact diameter tolerance and the size range required for your mill. Clarifying these specifications reduces the risk of receiving non‑conforming media.
Discuss incoterms with Chengde Rongmao to decide whether FOB or CIF from the nearest Chinese port, such as Tianjin or Dalian, best fits your supply chain. Ask for an estimated lead time based on the order volume, as the supplier does not publish this information. Payment is commonly arranged via irrevocable L/C or T/T after receipt of the mill test report. Confirm any freight forwarder requirements early to avoid delays.
Arrange a third‑party inspection at the factory before shipment to verify hardness, impact toughness and the broken‑rate performance against the supplied data. Request the full mill test report and a certificate of conformity for each batch. Ensure that the packaging - typically wooden crates of 500 kg - includes internal bracing to prevent movement during transit. Discuss any post‑delivery inspection procedures with your buyer to safeguard quality.
