Import Grinding Ball, Cast Ball, Steel Ball, Mill Ball — Buy in Bulk from Supplier in China

The product is a cast steel grinding ball supplied by Anhui Ruitai New Materials & Technology Co., Ltd., intended for use in ball mills and rod mills. Each ball is produced with a hardness of HRC 60‑66, providing resistance to wear during intensive milling. The microstructure comprises a martensitic matrix with dispersed carbides, which contributes to the ball’s strength. The supplier lists the balls as suitable for heavy‑duty applications in mining, cement and power‑generation sectors.

The balls are made from chrome‑bearing steel, a material commonly used for milling media because of its balance of hardness and toughness. Typical industry grades for such balls correspond to AISI 52100 or equivalent, offering a density of about 7.8 g/cm³. Standard size ranges for grinding balls run from 10 mm to 200 mm with a tolerance of ±0.1 mm, and a surface roughness of Ra ≤ 0.8 µm. These characteristics help maintain consistent grinding efficiency and reduce the frequency of ball replacement.

End users such as mineral processors, cement manufacturers and power‑plant operators select these balls to improve throughput and lower maintenance costs. The supplier states that packaging is secured for bulk shipment and that terms such as FOB or CIF can be arranged. Potential buyers should confirm the minimum order quantity, exact size required and any certification documents before finalising the contract.
