2. Forged Steel Grinding Media Balls Application
Forged grinding balls are used in ball mills, mainly in mines, cement plants, power plants and so on.
3. 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.
4. Forged Steel Grinding Media Balls Manufacturing process
Forged grinding ball is forged by air hammer after being heated by electric furnace.
5. Test
① Factory 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.
② The third party test
According to the customer different demand, forged grinding balls can be tested by any third party.
6. Packing
Forged grinding balls are usually packed in container bags and steel drums, it can also be customized according to different customer needs.
