Shandong Huamin Steel Ball Joint-stock Co., Ltd. supplies 140mm (5.5 inch) grinding media balls engineered for mineral processing and ball mill operations. These forged steel balls are made from a high carbon alloy steel, chromium-carbon grade, and achieve an ultra-high hardness of HRC 55-65 on both the surface and throughout the volumetric core. The product range includes diameters from 120mm to 150mm, with this listing focusing on the 140mm size.
The material composition and forging process are designed to deliver high wear resistance and a low breakage rate, which are critical performance metrics in grinding applications. The use of a special high carbon steel is typical for grinding media, as it provides the necessary hardness and toughness to withstand repeated impact and abrasion in ore and cement mills. The balls are intended for use in ball mills where consistent particle size reduction is required.
International buyers in the mining, cement production, and ore processing industries are the target market for this product. The balls are typically sold in bulk by metric ton for export. Key sourcing details such as the exact price per metric ton, minimum order quantity, and specific bulk packaging configuration for sea freight are not listed and must be confirmed directly with Shandong Huamin for accurate procurement planning.

Before placing an order for 140mm grinding media balls from Shandong Huamin, verify the exact chemical composition and mechanical properties. Request the supplier's material specification sheet and, ideally, a mill test certificate (MTC) for a sample batch. This report should confirm the carbon, chromium, and other alloying element percentages, as well as the actual hardness values, to ensure they meet the HRC 55-65 claim and your mill's requirements.
For logistics, confirm the bulk packaging method and weight per unit package. Grinding balls are dense and heavy, so container weight limits (typically 20-26 metric tons per 20ft container) are a key consideration. Clarify the shipping terms (e.g., FOB from the nearest Chinese port, likely Qingdao or Tianjin), the lead time from order confirmation to port readiness, and the payment terms. Also, discuss the process for handling any shortage or damage claims upon arrival.
Implement a quality check upon receipt. While full testing is impractical for every ball, you can conduct random sampling for hardness testing using a portable hardness tester. Measure the diameter of a sample to check for consistency. Monitor the performance of this batch in your mill, tracking consumption rate (kg/ton of ore processed) and breakage incidents. This data will help you benchmark the supplier's product against competitors and inform future purchasing decisions.
