Wear resistant ball mill discharge liner with long service life
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
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
