Ball Mill Discharge Grate Plate OEM Casting For Ore Grinding
Product Description
This OEM‑cast ball mill discharge grate plate is heavy‑duty wear‑resistant casting spare part for grate‑type ball mills. Used for mineral ore coarse and medium‑fine grinding, it discharges qualified fine ore while retaining grinding media and coarse particles for re‑grinding. Multiple alloy material options, custom dimensions and slot apertures per drawings, complete MT, UT, 3D‑scanning inspection documents are available.
Product Advantages
- Excellent impact and abrasion resistance for long‑term heavy‑duty ball mill operation
- Precisely processed slot apertures to stabilize ore discharging particle size
- Retain grinding media and coarse particles for secondary grinding, reduce over‑grinding
- Optimize internal ventilation and lower material blockage risk at discharge end
- Custom‑manufactured to fit various models of grate‑type ball mills
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
Every ball mill discharge grate plate undergoes strict factory inspection before shipment for heavy‑duty ore grinding conditions. Inspection scope includes visual appearance check, magnetic particle testing MT, ultrasonic testing UT, dimensional inspection and 3D scanning. Bolt fitting test is performed to verify assembly compatibility. Raw material chemical composition and hardness test confirm material grade meets specifications. Defective castings will be rejected. Full inspection reports and quality certificates are available upon request for project acceptance.
- Visual inspection for surface defects, burrs and irregularities
- Nondestructive testing MT magnetic particle testing and UT ultrasonic testing
- Dimensional verification or 3D scanning to meet drawing tolerance
- Bolt fitting test to guarantee smooth field assembly
- Chemical composition & hardness test to verify alloy material
- Inspection reports and quality certificates supplied 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.
