FAQs
What is the difference between forged grinding balls and cast grinding balls?
Forged grinding balls are made by heating and shaping high-carbon or alloy steel under high pressure, resulting in superior hardness, impact resistance, and longevity. Cast grinding balls are produced by melting and pouring metal into molds, offering a cost-effective solution for less demanding grinding environments. Forged balls excel in high-impact mining operations, while cast balls are ideal for lower-impact scenarios like cement or coal grinding.
How do I choose between forged and cast grinding balls?
Choose forged balls for high-impact, large-scale mining (e.g., copper, gold) where durability and low wear rates are critical.
Choose cast balls for cost-sensitive applications with softer materials (e.g., limestone, coal) or smaller operations.
Can it be customized as per our requirements?

This Skilsaw is powered by our largest 15 amp Dual-Field™ high torque motor so you will make the last cut as precisely as you did the first cut. Exclusive 60-degree bevel. High torque Dual-Field™motor. Legendary SKIL durability.
Can you customize the size and hardness of grinding media?
Yes! We offer fully customizable solutions. Specify your required diameter (e.g., 20–150mm for balls), hardness (HRC 50–65), and material composition to match your mill’s operating conditions (e.g., ore hardness, rotation speed).
What materials are used in your grinding rods and mine liners?
- Grinding Rods: Made from high-carbon steel or alloy steel, heat-treated for optimal wear resistance and toughness.
- Mine Liners: Constructed from high-manganese steel, chromium steel, or composite alloys to withstand abrasion and impact in mills.
