Wear liners protect the structure behind them from rubbing material and impact. They are replaceable wear parts, so their condition needs to be monitored before wear reaches the equipment they protect.
What To Inspect On A Worn Liner
Record remaining thickness, cracks, distortion, loose fasteners, and damage around mounting holes. Check whether the structure behind the liner is exposed or damaged.
Compare measurements with the equipment’s maintenance limits and earlier inspection records. A shiny surface or a photograph alone cannot establish the remaining thickness.
Setting A Replacement Limit
There is no single replacement thickness for every liner. The limit depends on the equipment design, loads, mounting arrangement, and required protection.
Use the equipment manufacturer’s requirements and the maintenance plan for the installation. Plan replacement before the liner can no longer protect the structure behind it.
Replacing Individual Plates Or A Complete Set
The choice depends on how wear is distributed, the condition of nearby plates, access, and planned downtime. Replacing a complete set may make sense during a scheduled shutdown; local replacement may suit an isolated worn area.
Check the fit between adjacent plates and inspect the supporting structure before defining the replacement work.
Choosing The Replacement Grade And Thickness
Hardox® grades offer different combinations of hardness and toughness. Selection should account for the material passing over the liner, impact loads, corrosion, operating temperature, and fabrication requirements.
A change in grade does not automatically justify a change in thickness. Review the design and mounting requirements together.
What To Send For A Replacement Quote
Send BSF a drawing or sample, overall dimensions, hole pattern, mounting details, and photos of the worn areas. Include thickness measurements, the current grade if known, and a description of the material being handled.
Tell us whether the enquiry covers individual plates or a complete liner set, and include any planned shutdown date.
