Cr-Mo Steel Casting Product Liners for SAG Mill

Application

the semi-autogenous mill lining plates are used to protect the mill's body from the direct impact and wear of grinding ball and materials.  the different shapes of the lining plate are used to adjust the movement state of the mineral, thereby enhancing the efficiency of grinding and crushing. which is helpful to improve the grinding efficiency, increase the output and reduce the metal consumption.  the semi-autogenous mills are with larger diameter, larger grain size, low filling ratio of steel balls, the ore itself needs to act as part of the grinding media, which requires semi-autogenous mill lining plate to have certain degree of hardness to resist grind ball fatigue wear, this also need to resist cutting wear from edges and corners of the ore. Due to the larger diameter of the semi-autogenous mill, it required to reach a sufficient impact and toughness value , so as to avoid deformation and fracture failure. Therefore, the design needs higher requirements.

Property and advantages

1.High wear and impact resistance

With scientific and reasonable formulation of alloy elements, the semi-autogenous mill lining plate has good physical and chemical properties. So it can withstand high impact, produce hardened layer around the alloy surface constantly during the application, and improve the wear resistance.

2.High strength, high toughness

By using the special quenching medium agent with thermal stability in the quenching process, Semi-autogenous mill lining plate combine high strength, high hardness and high toughness perfectly, since greatly improve the impact toughness, so can be used in semi-autogenous mill has a larger diameter, satisfy high impact and wear resistance technological requirements.

3.High cost-effective, strong adaptability

Through the independent designed heat treatment process of our company, semi-autogenous mill lining plate has a unique feature with quenching, combine high hardness and high toughness. So that the product not only has good wear resistance and high impact load resistance, but also improves the grinding efficiency and increases the machine-hour capacity.
