Ball vs. Rod Mill: What's Better for Grinding? – Valid Words
Energy Consumption. Ball mills offer a lower energy storage capacity than rod mills, and balls take up more space than rods. This means the overall cost is typically higher for ball mills. Ball mills are generally used for wet grinding due to their greater energy efficiency. On the other hand, rod mills are better for grinding dry materials.
