Frequently Asked Questions

What is the difference between forged and cast grinding balls?

Forged steel balls are made by heating and hammering steel billets, resulting in higher density, hardness, and wear resistance. Cast iron balls are poured into molds and are typically more economical for large-volume applications. Forged balls are preferred in high-impact environments like gold mining.

What sizes do you offer?

We manufacture grinding balls from 15mm to 150mm in diameter, grinding rods from 40mm to 120mm in diameter and up to 6 meters in length, and cylpebs in various cylindrical dimensions. Custom sizes are available upon request.

Do you provide product certifications?

Yes, we provide material test certificates (MTC), SGS inspection reports, and can arrange third-party inspections as required by customers. All products are traceable by batch number.

What is your minimum order quantity (MOQ)?

Our standard MOQ is 1 metric ton per size, but we can accommodate smaller trial orders for new customers. Container loading optimization is available for mixed product shipments.

How do you ensure consistent quality?

We have an in-house quality control center equipped with spectrometers, hardness testers, impact testers, and metallographic microscopes. Every production batch undergoes rigorous testing before shipment.
