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
