⑥ Production Process
Cast Balls and cylpebs are melted in electric furnace and poured into moulds after scientific proportioning. High chromium balls and cylpebs are also processed by oil quenching.
⑦ The Abrasion of the cast balls when grinding the cement
Material | Abrasion | Breakage | Size(mm) |
Low Chrome Cast Ball | 85-105g Cast Balls /Ton Cement | <2% | 10-150mm |
Medium Chrome Cast Ball | 50-80g Cast Balls /Ton Cement | <1.5% | 10-150mm |
High Chrome Cast Ball | 35-60g Cast Balls/Ton Cement | <1% | 10-120mm |
High Chrome Cylpebs | 35-60g Cylpebs/Ton Cement | <1.5% | 12×18-35×40 |
Low Chrome Cylpebs | 65-95g Cylpebs/Ton Cement | <1% | 12×18-35×40 |
Micro Cylpebs | 6×6 8×8 10×10 12×12 15×15 |
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
① According to the different customer need and usage.
② According to the ball mill size, dry grinding or wet grinding. We can recommend you the most suitable products.
6. 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.
