forged grinding steel ball for ball grinding machine grinding ball mill Austenite-bainite grinding ball is a kind of grinding ball, superior to the present widely used low-chromium ball, high-chromium ball, and variuos forged ball. The balls can be used in fields such as metallurgy mine, ore dressing, coal-grinding and cement production , and are manufactured by Chengde Rongmao Cast Iron Company Ltd. Its product size is 60mm, 80mm, 100mm, 120mm, 130mm, and especially the biggest size of 150mm. Our annual output is about 50,000 tons for the balls. Chemical Composition (%)
