Advantages of High Chrome Grinding Media Balls

  • The new generation of energy-saving grinding balls developed by our company, namely high chrome grinding balls, has almost zero hardness difference between the surface and core of ordinary cast steel balls.


  • At the same time, the ball consumption, breakage rate, and out-of-round deformation rate are significantly lower.


  • Compared with ordinary high-chromium steel balls, Chengxin high chrome ball shows better performance. It has been recognized and trusted by more and more customers.


Quality Control Measures for High Chrome Grinding Balls

  • Our company has a strict quality management system and has passed the quality management system certification. Products such as our high chrome ball must undergo five strict quality inspections from raw materials entering the cast grinding balls factory to final finished products being put into storage.


  • When raw materials enter the factory, they need to undergo the first inspection. Then, after smelting, the second inspection is performed, and the third inspection is performed after pouring and forming.


  • After the semi-finished product is qualified, the fourth appearance inspection is carried out. After heat treatment, the fifth level of hardness, chemical composition, metallographic structure, falling ball fatigue life, and other components and mechanical properties are tested.


  • Only after they are finally qualified can they be bagged and put into storage.


What are high chrome steel grinding media balls used for?

High chrome steel grinding media balls are essential in cement mills, where they play a critical role in the crushing and grinding of raw materials and clinker during the cement production process. These high chrome balls are specifically designed to withstand the rigorous conditions of milling, offering superior wear resistance, high hardness, and corrosion resistance. By efficiently breaking down the materials, high chrome grinding media balls help ensure a consistent and high-quality cement product, ultimately enhancing the overall efficiency and productivity of the cement manufacturing process.
