As the leading equipment of material grinding in the cement industry, ball mill has been widely used. The grinding body is an important consumable material in the operation of the ball mill. Its quality is related to the output and running rate of ball mill and directly affects workers’ production cost and labor intensity. It is well known that steel balls are the main grinding bodies used in mills. Over the years, through the research and development of the vast number of scientific and technological workers, the types of grinding balls have changed from ordinary carbon steel balls, to bainite grinding ball, low (middle, high chrome alloy grinding ball, and other fields. The cast alloy high chrome grinding ball is a kind of abrasive body with high anti-wear and anti-impact ability. The application test proves that it is a kind of ideal abrasive body with low production consumption and good economic benefit.
