Alumina wear tiles & liners
Dense 92 % or 95 % alumina tiles that take the wear instead of the steel. Plain and weld-on tiles, mosaic and hexagonal mats, cylinders and custom shapes for chutes, hoppers, pipes and other surfaces where material slides and scours.
Forms we supply
| Form | Typical dimensions* | Fixing | Typical use |
|---|---|---|---|
| Plain tile | 150×100, 100×100, 100×50 mm; 6–25 mm thick | Bonded | Chutes, hoppers, flat or gently curved faces |
| Weld-on tile (centre hole) | 150×100, 100×100 mm; 15–25 mm thick | Welded stud + ceramic cap | Vertical and overhead faces, vibration, warm or wet duties |
| Mosaic tiles on mats | 10×10 to 20×20 mm tiles, 3–8 mm thick, on sheets of about 500×500 mm | Bonded | Curved surfaces, pipe and cyclone interiors |
| Hexagonal tiles on mats | About 20 mm across flats; 3–13 mm thick | Bonded | Curved surfaces where joints must stay tight |
| Cylinders, dimpled and serrated tiles | e.g. Ø20×12, Ø20×20 mm; 20×20×5 mm | Vulcanised by panel makers | Rubber-ceramic panels and pulley lagging |
| Custom shapes | To drawing | Bonded, welded or interlocking | Transfer points, bends, wear parts |
*Typical dimensions from partner factories’ standard ranges. Other sizes to drawing; final dimensions and tolerances are confirmed on the quotation.
Custom shapes and assemblies
Cones, cylinders and transition pieces are built from shaped tiles, fitted and numbered at the factory so they go back together on site.
Choosing the fixing method
How a tile is held decides where it can be used. The alumina tolerates high steady temperatures; the adhesive, rubber or stud usually fails first.
| Method | Use it when | Limits |
|---|---|---|
| Bonded (adhesive) | Ambient to moderate temperature; mostly sliding wear; horizontal or inclined faces | The adhesive, not the alumina, sets the temperature and chemical limit. We check its rating against your maximum and fluctuating temperature. |
| Weld-on (stud + cap) | Vertical and overhead faces, vibration, warm duties, wet corrosive duties such as flue gas desulphurisation | Stud and weld must suit the corrosive medium; tiles must be thick enough for the countersunk hole. |
| Vulcanised in rubber | Impact together with abrasion | Rubber limits the temperature — see rubber-ceramic panels. |
| Interlocking / dovetail | Where adhesive is unsuitable and studs are impractical | Needs a matching steel profile; made to drawing. |
Where alumina tiles are a poor fit
- Rapid temperature swings, quenching or frequent hot starts — alumina is sensitive to thermal shock.
- Large lumps falling from height onto bare tiles — use rubber-ceramic panels at the impact point.
- Duties where the adhesive or stud would fail long before the tile — change the fixing, not the grade.
92 % or 95 %?
92 % alumina is the standard grade for wear tiles. 95 % wears more slowly and costs more; we suggest it where wear is severe enough that relining downtime outweighs the price difference. Each quotation states the grade.

Questions
How thick should the tiles be?
It depends on how fast the surface wears now and how long you want between relines. Send the current lining thickness and its service life; we propose a thickness and explain the trade-off against weight and cost.
Can tiles follow a curved surface?
Mosaic and hexagonal mats follow curves. On large diameters, such as big silo walls, flat tiles can often be fitted directly because the curvature is small. Tight radii need mats or shaped tiles.
Do you supply the adhesive or studs?
Yes, adhesive or weld studs and caps can be supplied with the tiles, matched to the duty. Installation is by your team or a local contractor, following the factory’s installation notes.
Send the surface and the duty.
A drawing or photos with dimensions, the material and its temperature are enough to start. We reply within one business day.
