Raw Material:
Strict quality control of steel material from BIG STEEL FACTORY GROUP.You know the good grinding balls quality depends on the good raw material.
Prodcution Line:
1.Traditional Hammer Forging: Raw material-Cutting-Heating-Forging-Quenching-Tempering-Testing-Packing
2. Hot Rolling
Testing:
Quality control for each production shift (4hours/Shift);
Hardness, chemical elements and impact testing after production for each production shift;
SGS –third party testing before each delivery
Packing:
Container bags(Net weight:1000KGS) or Steel drums(850-900KGS) or in clients' requirements
Our advantage:
