grinding ball

Jinan Haoyang Casting and Forging has been dedicated to the research and production of wear-resistant steel balls for 14 years. They are made from high-quality steel through precise forging processes, featuring high hardness and low wear characteristics. They are suitable for heavy-duty grinding scenarios in industries such as mining, cement, and metallurgy. As a high-tech enterprise, the products have passed ISO quality system certification. The specifications range from 20mm to 150mm. Customized material formulas can be provided according to customer requirements, ensuring a 30% increase in grinding efficiency. They have gained the trust of customers both at home and abroad.

Dense forging structure without internal porosity. Ultra-low breakage rate ≤0.5%. No broken balls or flat balls during grinding, effectively reducing mill downtime.

We have rich experiences in supplying the grinding balls to Mining industry , cement plant , thermal power and chemical industry. 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 .

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.
