Grinding Media Balls

Jinan Haoyang Casting and Forging has seized the global opportunities in mineral development. Its forged steel balls that comply with YB/T 091 standards have entered international mineral projects in countries such as the Democratic Republic of the Congo and Chile. The products cover specifications ranging from Φ70mm to Φ200mm, are compatible with various grinding equipment, and can be supplied in single batches of over 1,000 tons. The company has set up 3 service stations overseas. In 2025, overseas orders will increase by 52%, and the share in the new energy mineral sector will exceed 40%, helping to achieve efficient global resource development.

Thanks to the growth of the global steel ball market, the export orders of Jinan Haoyang Casting and Forging increased by 40% year-on-year. The US market accounted for over 60% of its sales. Its core forged steel balls are designed with wear-resistant properties to meet the demands of overseas mines. By leveraging its transportation hub advantages, it shortens the delivery cycle. It is expanding into emerging markets such as Southeast Asia and expects its annual export volume to exceed 8 million.

The gradient hardening forged steel balls developed by China have achieved a double breakthrough in terms of hardness (65HRC) and toughness (18J/cm²), with a 50% increase in lifespan. Using the 42CrMoV alloy and post-forging residual heat quenching process, the single consumption of 80mm steel balls is 0.45kg/t of raw ore. They have been certified by BHP Billiton and the first 2,000 tons of orders will be used for the iron ore project in Australia. This technology fills the international gap and is planned to have a 35% market share in the high-end market by 2026.

High Hardness Grinding media balls main benefit :
Improved Wearing rates
No deformation after using in Ball mill
Lower Breakage rate
Uniform Hardness throat

Haoyang was built using the most advanced hot rolling automatic machine or Labor forging machine .
We managed to achieve very high levels of quality in grinding steel balls .

Raw material Quality Control : The forged grinding balls ' steel rods are purchased from the famous steel company in China ( 50,000 Tons annually ). It will be strictly inspected before into the warehouse.

Production Line : Forged grinding balls mainly use Automatic rolling machine for 20mm to 70mm balls .
Above 70mm to 150 mm , we will use the labor forging hammer , which will increase the grinding balls intensity and tougness .
