Ball Mill Discharge Liner OEM Casting Wear Resistant Long Service Life
This OEM‑cast ball mill discharge liner is heavy‑duty wear‑resistant casting spare part for grate‑type ball mills. Featuring outstanding wear resistance and long service life, it is fitted at the mill discharge end to protect mill housing and separate qualified ore from grinding media. Multiple alloy material options, custom dimensions per drawings, complete MT, UT and 3D‑scanning inspection documents are available.
Product Advantages
- Superior wear resistance and impact resistance for heavy‑duty mining working conditions
- Long service life to reduce replacement frequency and cut operating costs
- Reliable protection for ball mill discharge end housing
- Stable material separation and smooth ore discharging performance
- Reduce material blockage at the discharge section
- Custom‑made to match various ball mill models according to drawings
Custom Service
At SXYH, we deliver full‑range customization services for ball mill discharge liners to satisfy various mineral ore grinding requirements. We customize overall dimensions and structural details strictly following your technical drawings. Multiple alloy grades including high‑manganese steel, ultra‑high‑manganese steel and Cr‑Mo multi‑alloy steel are selectable for different impact‑wear working conditions. Custom marking and model numbers are supported. All customized products comply with ASTM ISO CE standards. Lead time and payment terms depend on your order specifications.

Bolt Fit Test
Check whether the threaded holes or mating holes on the casting allow for smooth assembly with the bolts.
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.
