Basic Knowledge Of Mining Grinding Balls

The international market demand for mining grinding balls is about 18-20 million tons per year, and they are mainly used in ball mills as media for grinding materials. It is widely used in mineral processing plants, cement and other industries.
The types of steel balls used in mining: 1. Cast steel balls: ordinary cast cast steel balls are produced by non-electric furnaces, low-chromium alloy cast steel balls are melted in electric furnaces, medium chromium alloy cast steel balls are melted in electric furnaces, high-chromium alloy cast steel balls are melted in electric furnaces, and ultra-high chromium is melted in electric furnaces Alloy cast steel balls (chromium content 22%-30%) 2. Forged (rolled) steel balls: 50mn, 60mn, 65mn and high alloy steel B2, B3, BU material forged hot-rolled steel balls 3. Miniature steel balls Both steel grit and steel shot: one is to cut the shot with a steel bar, and the other is to pour it with molten steel to remove rust and polish the smooth surface.
