■ SAG Mill Discharge Grates main function is to discharge minerals with qualified particle size and refractory stones. Therefore, if there are many stubborn minerals in the mineral, two different Grates are installed at the discharge head of the mill. The discharge Grates must ensure that there are no casting defects such as shrinkage holes and shrinkage in the Grates to prevent it from breaking.
■ SAG Mill Discharge Grates main material : CrMo alloy .
■ casting process uses Procast for simulation analysis to eliminate casting defects and design a reasonable casting process.
■ Casting board adopts resin sand modeling to ensure the smooth appearance of grid and accurate size.
■  Heat Treatment process： Normalizing + Tempering ,which has uniform hardness HB325-375, and has good toughness and wear resistance.
■ The assembly surface of the SAG Mill Discharge Grates and the mine-lifter requires fine grinding or tool correction.
