Ball Mill Discharge Grate Plate OEM Casting Parts For Ore Fine Grinding
Product Summary
This ball mill discharge grate plate is a vital wear‑resistant casting spare part installed at the discharge end of grate‑type ball mills for ore fine grinding. It lets qualified fine‑ground ore pass through while retaining grinding balls and coarse particles inside for re‑grinding. Made of high‑manganese steel, it delivers strong impact and abrasion resistance. OEM custom sizes and slot apertures are available with complete inspection documents.
Product Advantages
- Excellent wear and impact resistance for long service life
- Precisely machined slot aperture to control discharging fineness
- Effectively separate grinding balls and fine ore, improve fine‑grinding efficiency
- Reduce material blockage at discharge end
- Custom‑manufactured for various grate‑type ball mill models
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.
Product Inspection
- Strict full‑process factory inspection for ball mill discharge grate plate
- Visual inspection for surface defects burrs and irregularities
- Nondestructive testing including MT magnetic particle testing and UT ultrasonic testing
- Dimensional verification and 3D scanning to guarantee drawing tolerance
- Bolt fitting test to ensure smooth on‑site assembly
- Chemical composition and hardness test to verify material quality
- Inspection reports and quality certificates available on request
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.
