Ball Mill Lifter Liner High Manganese Steel Cast Wear Spare Parts

Ball Mill Lifter Liner High Manganese Steel Cast Wear Spare Parts

Product Summary

Liner is mainly used in AG Mill, SAG Mill, Ball mill, Bar mill and other grinding equipments. Our ball mill lift liners are cast from high-manganese cast steel and are installed in the ball mill shell to lift the grinding media and material, thereby improving grinding efficiency and providing impact resistance and wear resistance. We supply OEM replacement liners and offer third-party testing for MT, UT, and dimensional compliance.

Product Inspection

Mold Manufacturing: Wooden Molds , Aluminum Molds ,Plastic Molds
Select and machine the appropriate mold based on the production batch size and casting requirements.

Rough machining, such as removing surface burrs, etc.

Heat Treatment
Select an appropriate heat treatment process based on the casting material and performance requirements to improve the casting’s microstructure and properties.

Dimensional Inspection
Inspect critical areas—such as length, hole diameter, thickness, and flatness—to ensure they meet the tolerances specified in the drawings. Focus on inspecting mounting interfaces, bolt hole spacing, and wall thickness.

MT Magnetic Particle Testing
This method is based on the principle that when ferromagnetic materials are magnetized, “leakage magnetic fields" are generated at surface or near-surface defects. These leakage magnetic fields attract magnetic particles applied to the workpiece’s surface, forming visually detectable magnetic traces (which are much larger than the actual defects), thereby clearly indicating the location, size, and shape of the defects.

UT Ultrasonic Testing
This method utilizes the propagation characteristics of ultrasonic waves in materials. When sound waves encounter defects or heterogeneous interfaces within a material, they undergo reflection, refraction, and attenuation. The instrument determines the location, size, and nature of defects by receiving and analyzing changes in the energy of the reflected echoes or transmitted waves.

Hardness Testing
Examine the indentation resistance of the casting’s surface to verify that the hardness values meet the requirements specified in the drawings and that there are no excessive variations in hardness between different areas of the same casting.
