The 25mm-150mm high carbon grinding steel ball from Shandong Huamin Steel Ball Joint-stock Co., Ltd. is engineered for concentrator mines and ball mill applications, offered in diameters from 20mm to 150mm (1"-6"). The product features surface hardness of 55-67 HRC and volume hardness of 56-64 HRC, with impact toughness exceeding 12 J/cm² and a breakage rate below 1%. Dimensional tolerances vary by size, with roundness percentages as low as 4% for larger diameters, ensuring consistency in grinding performance.
Manufactured from high carbon steel, these grinding balls resist abrasion and impact without cracking or losing circularity, a critical requirement for mineral processing. The material composition is optimised for toughness, with chemical elements balanced to meet the demands of high-stress grinding environments. Industry standard for such media typically includes chromium or manganese additions to enhance wear resistance, though exact alloy percentages should be confirmed with the supplier for this batch.
Concentrator mines and cement plants use these balls for ore and material comminution, where durability and hardness directly influence mill efficiency. Buyers typically source in bulk, with packaging options including steel drums (800kg capacity) or nylon bags (50kg, 100kg, 1000kg), palletised for export. Shandong Huamin supplies directly from Zhangqiu, Jinan, with logistics tailored to international shipping standards.

Before ordering, verify the exact chemical composition of the steel, particularly the chromium and manganese content, as these directly affect wear resistance and longevity in grinding applications. Confirm whether the supplier provides third-party test reports for hardness, impact toughness, and breakage rate, as these are critical for quality assurance in mining operations.
Logistics confirmation should include Incoterms (e.g., FOB Qingdao), lead time for production and shipping, and whether the supplier can accommodate custom packaging or palletisation. For bulk orders, clarify if the steel drums or nylon bags meet international shipping regulations and if additional export documentation, such as a packing list or certificate of origin, will be provided.
Quality checks should include visual inspection for surface defects, dimensional verification using calipers, and hardness testing with a portable tester. Request a sample batch for trial grinding to assess performance under your specific mill conditions. Ensure the supplier can provide a mill test certificate or equivalent documentation to validate the mechanical properties of the grinding balls.
