2. grinding steel balls Application
① Mining ( Gold, copper, iron ore )
② Cement plant
③ Coal mill
④ Sag mill
⑤ Industry
⑥ All the ball mill or rods mill machine
3. grinding steel balls 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.
① 45#
② 60Mn
③ B2
④ B3
4. grinding steel balls Manufacturing process
Forged grinding ball is forged by air hammer after being heated by
electric furnace.
5. grinding steel balls 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. grinding steel balls Packing
Forged grinding balls are usually packed in container bags and
steel drums, it can also be customized according to different
customer needs.
