50mm Air Hammer Forged Grinding Balls Forging Steel Balls For Ball Mill
1. Forged Steel Balls Application
Forged grinding balls are used in ball mills, mainly in mines, cement plants, power plants and so on.
2. Classification
According to the different chemical elements , forging grinding balls can be divided into C45,60Mn,B2 and B3. At present, the above four materials are widely used all over the world, that’s the conventional materials, if there are special needs, can be customized.
3. Manufacturing process
Forged grinding ball is forged by air hammer after being heated by electric furnace.

5. Test
Forged grinding balls test is an very important step. Real-time detection will be carried out in the production process. Balls produced in each shift will be sampled in large quantities and tested for size, hardness, chemical composition, drop test, core pulling and impact value to ensure the quality of steel balls.
