Table liners
The table liner is the track the rollers run on. It wears a groove under the rollers. The depth of that groove is often what forces the mill to stop.
- Works in
- Grinding table segments of vertical roller mills and bull ring segments of bowl mills.
- Industries
- Cement, Thermal power and steel
- Materials
- High-chromium iron, Ni-Hard
- Size
- Single pieces from 3 kg to 7 tonnes, to drawing
- Supplied
- As cast, or machined to drawing
- Inspection
- Chemistry and hardness on every heat; UT, MPI or DPT and a dimensional report as specified

- Yes. Send the part or photographs with key dimensions and we will reverse-engineer it
01
How it fails and what we do about it
- 01Track wear under the rollersHigh-chromium iron, through-hardened for the segment section.
- 02Segments working looseFixing faces and clamping surfaces held to drawing.
- 03Steps and gaps between segmentsSegments checked for fit as a complete set.
02
Choosing the grade
Typical values from the governing standards. A metallurgist confirms the grade for your duty with every quotation.
Ni-Hard (nickel-chromium white iron)
Coal mills and bowl mill bull rings.
ASTM A532 Class I · IS 4771 · ISO 21988 / EN 12513
03
What we control
- Hardened through the sectionWhite iron alloyed and heat treated for the thickness of each segment, not just its surface.
- Structure checkedMicrostructure examined with an image analyser, so carbide and matrix are verified, not assumed.
- Fit as a setSegments checked against each other and against gauges so they assemble without forcing.
- Machined to drawingBores, journals and fixing faces finished on vertical lathes and machining centres.
