We are one of the largest factory specialized in producing Forging Grinding Media Ball, Rolling Grinding Media Balland Casting Grinding Media Ball in China. It was founded in 1988, located in Zhangqiu City, Shandong Province, China. Annual Production Capacity is 50,000 metric ton. There are 120 employees, covering an area of 15,000 square meters. Our products have been exported to more than 30 countries and got a lot of praise. We have large-scale production workshop, advanced production equipment and perfect quality assurance system. Our company has passed ISO9001:2000 quality system authentication and we always keep sincere service promise.

The production of casting steel balls is to melt the waste raw material such as waste steel, waste iron with medium frequency induction furnace. In the process of melting, add suitable amount of precious metal alloys(such as Ferrochrome, ferromanganese, ferro-vanadium ) to the furnace. When the temperature of the molten iron is more than 1550°C and can meet the requirements of the technics,pour the qualified molten iron to steel moulds or steel production line moulds. The content of chrome of high chrome alloy casting steel balls is ≥10.0%, the content of carbon is 1.80%-3.20%. Since the national standards require the HRC≥58, ak≥3.0J/cm², to up to this hardness, the high chrome balls must be quenched and tempered. After quenched and tempered, the hardness(HRC≥60) is higher, the wear-resistance is more than 2.5 times of forging balls.

Established in 2000, We Jinan Zhongwei casting and forging grinding ball Co.,Ltd, are leading manufacturer and professional exporter of grinding media balls in China. with the annual output of 50,000 to 70,000 metric tons.
