Import Grinding Steel Ball — Buy in Bulk from Supplier in China

Shandong Huamin Steel Ball Joint-stock Co., Ltd. supplies grinding steel balls that are engineered for high performance in mineral processing, cement production and power‑generation applications. The product line covers diameters from 20 mm up to 150 mm, and the supplier offers two hardness grades: HRC 55‑65 for high‑chromium alloy and HRC 45‑50 for low‑chromium alloy. These balls are manufactured to achieve a breakage rate of approximately 1 %, which helps maintain continuous operation in grinding mills. The company promotes direct sourcing from the manufacturer to ensure reliable supply and competitive pricing.

The balls are forged from high‑carbon chromium alloy steel, a material widely accepted in the grinding media market for its wear resistance and toughness. In the sector, a surface finish around Ra 0.2 µm and a dimensional tolerance of ±0.02 mm are typical for achieving uniform charge distribution. The low breakage rate cited aligns with industry expectations for premium grinding media, and the dual‑grade offering allows users to balance cost against performance. Packaging is usually in 25 kg cartons, facilitating bulk handling and storage.

Key buyers include mining firms, cement factories and power‑generation plants that require consistent milling efficiency. Huamin provides flexible minimum order quantities and ships under FOB or CIF terms from its Yangjun Village facility in Zhangqiu, Shandong.
