With annual exports reaching US$2.5–5 million and a team of 51–100 skilled professionals, we ensure every grinding ball meets rigorous quality standards. These balls are engineered to enhance grinding efficiency, reduce wear, and extend the life of your mill, making them a reliable choice for mineral processing, cement production, and other bulk material grinding applications.
Our grinding balls are manufactured using advanced heat treatment technology and premium alloy steel, delivering consistent hardness and uniform microstructure. The included Mill Test Report provides detailed chemical composition, hardness, and impact test data, giving you full traceability and confidence in every shipment. Below is a summary of key specifications:
| Parameter | Value |
|---|---|
| Hardness (HRC) | 58–65 (adjustable per request) |
| Diameter Range | 20mm – 150mm (custom sizes available) |
| Material | High Chromium Alloy Steel (Cr ≥ 10%) |
| Impact Value | ≥ 5 J/cm² (tested per batch) |
| Warranty | 1 year (covers manufacturing defects) |
Key Features & Benefits:
- Enhanced Wear Resistance: The high chromium content and optimized heat treatment significantly reduce ball wear, lowering your consumption cost by up to 20% compared to conventional grinding balls.

Frequently Asked Questions
1. What is the warranty period for your grinding balls?
We offer a 1-year warranty covering manufacturing defects. If a ball breaks or shows abnormal wear due to material or workmanship issues within 12 months, we will replace it free of charge.
2. Do you provide a Mill Test Report for each shipment?
Yes, every batch is accompanied by a detailed Mill Test Report that includes chemical composition, hardness (HRC), impact value, and density. You can request a sample report before ordering.
3. What sizes are available, and can you customize?
Standard diameters range from 20mm to 150mm. We can also produce non-standard sizes, such as 17mm or 130mm, based on your mold requirements. Please inquire for custom sizes.
4. What is the typical hardness of your balls, and can it be adjusted?
Our standard hardness is HRC 58–65. For specific applications, we can adjust the heat treatment cycle to achieve a different hardness range (e.g., HRC 55–60 for low-impact mills or HRC 62–68 for high-wear conditions).
5. How are the balls packaged for sea freight?
We offer multiple packaging options: steel drums (typically 500–800 kg per drum), flexible big bags (1 ton each), or wooden pallets with shrink wrap. All packaging is suitable for long-distance shipping and can be customized per your handling requirements.
