The Cast iron grinding ball is excellent in surface quality, toughness, and resistance to impact and abrasion. It won't crack and lose circularity quickly. Grinding media is used in ball mills to pulverize or mix materials into powders The forged steel grinding ball must use super wear-resistant material to ensure abrasion resistance. Benefits include being able to be operated
