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. Packing

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