Grinding Table Liner Hardfacing Repair
Professional Rebuilding for VRM Grinding Table Segments & Wear Liners
JINHUA provides professional hardfacing repair and rebuilding solutions for grinding table liners, grinding table segments and other high-wear components used in vertical roller mills.
By combining automated hardfacing equipment, wear-resistant flux-cored welding wire and customized welding procedures, worn grinding table components can be rebuilt to restore surface profile, wear resistance and service life.
Our repair solutions are suitable for both preventive hardfacing and refurbishment of heavily worn table segments.

Why Do Grinding Table Liners Need Hardfacing?
Grinding table liners operate continuously under high pressure and abrasive material flow.
Typical wear problems include:
- Surface abrasion
- Material loss
- Uneven wear
- Reduced grinding profile
- Local cracking
- Worn previous hardfacing layers
If the wear becomes excessive, grinding efficiency and production stability can be affected.
Hardfacing rebuilding allows the worn surface to be restored without replacing the complete component.
Typical Repair Process
Wear Inspection
Check the liner or segment dimensions, wear depth and surface condition.
Surface Preparation
Remove damaged, cracked or unsuitable material where required.
Welding Procedure Selection
Select suitable welding wire, overlay alloy and hardfacing parameters.
Automatic Hardfacing
Deposit wear-resistant alloy onto the worn surface using mechanized or automatic welding equipment.
Profile Rebuilding
Restore the required grinding surface profile through controlled multi-pass welding.
Final Inspection
Check surface condition, dimensions and overlay quality before reuse.
Hardfacing Processes
Depending on the workpiece and wear condition, JINHUA can provide:
Benefits of Grinding Table Liner Rebuilding
Hardfacing repair can help:
- Extend component service life
- Restore worn grinding profiles
- Reduce replacement costs
- Reduce maintenance downtime
- Improve abrasion resistance
- Reuse high-value base components
- Reduce spare-part consumption
For large VRM components, rebuilding is often more economical than complete replacement.
