SAG mill liner from HENGIN is made of CrMo alloy, and its main matrix structure is pearlite and carbide. CrMo mill liner has superior strength and toughness matching, which can meet the requirements of the liner to deal with the conditions of high wear resistance and high impact toughness. It is currently the main international material selection standard for Mine SA, SAG mill liners.
■ SAG Mill Liner mainly includes parts

Feed head liner, Shell liner, Discharge head liner, Slurry elevator liner, etc.
■ HENGIN SAG Mill Liner Design and Simulation
HENGIN uses MilTraj and DEM software to design the SAG mill liner to accurately position the Toe. Use Procast software to simulate the casting of the liner to eliminate casting defects and ensure the quality of castings.
■ Manufacturing Process
casting process design→model making→resin mand modeling→molten mteel mmelting→mouring→molidification and thermal Insulation stress relief→cleaning and polishing→normalizing heat treatment→shot blasting→packaging.
■ HENGIN SAG Mill Liner Basic Property Description
◆Hardness: Hardness reflects the wear resistance of the material. In order to resist the grinding effect of metal ores with higher hardness, SAG mill CrMo liner has higher hardnessHB325-375;
◆Hardenability: The liner of the mine mill is thick . In order to ensure the uniformity of the structure and performance, the CrMo liner has high hardenability;
◆Corrosion Resistance: The mine mill liner is immersed in corrosive media, and the CrMo liner has high corrosion resistance;
◆ Abrasion Resistance: The interaction of corrosion and wear under wet grinding conditions will greatly accelerate the failure of the liner, and the CrMo liner has a high resistance to corrosion and abrasion;
◆Impact Toughness: to ensure that the liner does not break during use under wet grinding conditions, and the CrMo liner has high impact toughness. In short, the mining SA and SAG mill liner should have good comprehensive mechanical properties, hardenability, corrosion resistance and wear resistance, and it is not suitable to pursue a single performance σs≥950MPa,ak≥35J;
◆Microstructure: Pearlite + Carbide;
◆Grain Size Level: 7-8 ;
◆Liner Casting Maximum Hot Pitch Circle : 250-300mm;
◆Casting Dimension Accuracy Grade: CT11-CT12;
◆Mill Liner Wear Form: Mainly with impact wear as the main abrasive wear as a supplement.
■ Use Case Parameters
Hengin's Cr-Mo alloy steel mill liner provides Cr-Mo liners for CITIC, Tisco, Zijin Mining, China Gold, etc. Cr-Mo mill liners has been widely used in China, Australia and other places in copper, gold, iron, molybdenum and other mines.
