Steel grinding balls benefits
Our steel grinding balls has good surface quality, high impact value, strong toughness, good wear resistance, and low ball breaken and lose roundness rate.
We use a forging method to heat the metal until the temperature reaches 1100oC (±50oC). The forging machine is used to apply pressure to the metal blank to plastically deform it to obtain a certain mechanical property, shape and size.
The quality of steel grinding balls are 80% depending on the quality of the materials. We use raw material produced by the national extra-large steel mills. Forged steel balls are favored by users because of their low price and efficient wear resistance. For example, international mining giants Rio Tinto, BHP Billiton, Anglo Gold, etc. all use forged steel balls.

Steel grinding balls Processing
1. Forged grinding balls are hammer forged from selected high quality carbon and alloy steels. By hammer forged, the steel balls have good density and strengths in favor of impact grinding.
2. Steel grinding balls need to be heat treated by quenching and tempering to become more wear resistant.
3. Sampling inspection at any time during the production process to ensure the steel grinding balls are qualified
4. The produced grinding steel balls are classified and stored according to different sizes and specifications.
5. Packed the steel grinding balls according to customer's requirements, generally steel balls are packed by flexible container bags (1 ton /bag ).
6. Steel grinding balls packing by steel drums is 850-930kgs/drum.

Quality control
__________________________________________________________________________________________________________________________________________________we have a first-class laboratory and equipped with advanced testing equipment to ensure the quality:
spectrometer ( The wear resistance of steel grinding balls are mainly determined by its chemical composition. )
hardness tester (Testing the surface hardness of steel grinding balls )
laser cutting machine (Testing the core hardness of steel grinding balls)
impact tester (Ball mill with a diameter more than 6m, the larger the impact value, the lower the breaking rate. )
microscope ( Observe the density and structure of steel grinding balls )
drop tester ( Testing the service life of the steel grinding balls )
