1. Cast Iron Ball is popular grinidng media for ball mill, please
tell your size, chrome content or hardness, we will give the most
competition qutation ASAP.
Following is the detail:
2. Classification
According to the different chemical elements , Cast balls can be
divided into Low Cr,Medium Cr and High Cr. At present, the above
materials are widely used all over the world, that’s the
conventional materials, if there are special needs, can be
customized.
3. Manufacturing process
Casting balls are melted in electric furnace and poured into moulds
after scientific proportioning. High chromium cast balls are also
processed by oil quenching.

5. Test
① Factory test
Casting 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, casting balls can be
tested by any third party.
6. Packing
Casting balls are usually packed in container bags and steel drums,
it can also be customized according to different customer needs.
