During the test, the energy-saving grinding balls didn't deform or lose roundness from large to small, and the breakage rate was extremely low. Even under harsh industrial and mining conditions, it can show excellent performance! During use, the output per unit was increased, the filling rate and consumption rate was reduced,the using amount of grinding balls was saved, the grinding fineness was increased, and the electricity bill was saved. This solved the common problem of grinding media products that are easy to lose roundness, deform, and break. It truly achieved cost reduction and efficiency improvement for customers!

As one of the leading cast grinding balls factory, we developed the energy-saving grinding balls which didn't deform or lose roundness from large to small, and the breakage rate was extremely low. For small size grinding balls, we have 20mm grinding ball for example in the range Φ4mm-80mm. Even under harsh industrial and mining conditions, it can show excellent performance!
