Why minings should choose high chrome casting balls?This is Betty from Dexin Techonlogy, who is actively in grinding balls business for 15 years. Based on the verification and application of mining enterprises over the past ten years, we believe that it is an inevitable trend for mining enterprises to adopt high-hardness and high-strength high-chromium balls. Now, I will demonstrate this through an example. One of our overseas magnetite mine customers has a Pratt hardness of over 12, with 5 series, and two-stage grinding. The first and second stages both use 2745 overflow type ball mills. Previously, they were using local ordinary steel balls, and the steel ball settlement was done by chartering. For every ton of dry ore processed, the cost of steel balls was $0.64 per ton of ore. The steel ball loss was approximately 1.05 kilograms. In October 2024, this mine began using the mine-specific high-chromium balls provided by our company, with package grinding. The hardness of the steel balls is HRC 58-65, and the impact toughness is above 5 joules. After 4 months, the steel ball wear stabilized at 0.6 kilograms. Currently, the unit price of our steel balls is only $0.56, and the grinding cost per ton of ore directly drops to $0.085. This mine processes approximately 3 million tons of ore per year, and can save $255,319 in costs annually. Moreover, it has improved the grinding indicators. The market has repeatedly proven that it is a very wise choice for mining enterprises to repeatedly use high-hardness and strong-toughness high-chromium steel balls. Dexin technology just provide the benifit grinding balls for your business.
