Wear-resistant steel balls, also known as wear-resistant media for grinders, are consumables. Their main purpose is to grind materials to a finer particle size that meets application standards. They are widely used in ball mills across industries such as metallurgical mining, cement and building materials, thermal power generation, flue gas desulfurization, magnetic materials, chemical engineering, coal-water slurry, pellet ore, slag, ultra-fine powder, fly ash, calcium carbonate, and quartz sand. The global annual consumption of steel balls ranges from 30 to 50 million tons
