Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

1

How does chromium content influence steel grinding balls price and performance?

Higher chromium content (10%-21%) enables the formation of chromium carbides. These hard phases significantly increase the ball's resistance to abrasive wear, effectively lowering the total cost per ton of material processed.

2

Why is the hardness differential between surface and core critical?

A large difference creates internal stress, leading to breakage and loss of roundness. We maintain a differential within 0.2HRC to ensure maximum durability and structural integrity.

3

Can high-chromium balls be used in both wet and dry grinding?

Yes, our high chromium alloy balls are designed for excellent environmental adaptability and perform efficiently in both wet and dry grinding mill environments across various industries.

4

What are the advantages of the "M+C" microstructure?

The Martensite (M) and Carbide (C) combination provides a perfect synergy of high hardness for abrasive wear resistance and sufficient toughness to prevent shattering under high impact.

5

How do these balls reduce overall production costs?

By reducing the wear rate, you decrease the quantity of media required per ton of ore and minimize mill downtime for reloading, resulting in higher throughput and lower operational expenses.

6

What customizations are available for different mill requirements?

We offer tailored diameter options from φ15mm to φ140mm+ and adjustable chromium percentages (10%-21%) to match the specific ore hardness and grinding requirements of your operation.
