    3. Cement Grinding Balls Classification:



    4. The difference of the forged ball and cast ball


    ① Different production line

    ② Different raw material

    ③ Different chemical element

    ④ Different core hardness and core hardness


    5. How to choose the material


    According to the different customer need and usage.

    According to the ball mill size, dry grinding or wet grinding. We can recommend you the most suitable products.


    6. Ball Mill Balls Quality Control


    ① Factory Test

    Grinding cylpebs test is an very important step. Real-time detection will be carried out in the production process. Cylpebs 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 cylpebs

    ② The third party test

    According to the customer different demand, cylpebs can be tested by any third party.


    7. Packing

    Cylpebs are usually packed in container bags and steel drums, it can also be customized according to different customer needs.
