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:
1. We are a direct manufacturer,located in the largest production base of forged grinding steel ball in China.We are very pleased to offer you the most competitive price.All products with high quality would pass the third party inspection before shipment.
2. The Heat treatment technology is very perfect, especially the tempeing process,which increase the hardness of the forging steel ball and nake the product more wear-resisting.
