Wear-Resistant Alumina Linings

Ceramic tiles, bricks and lined pipe that protect chutes, hoppers, cyclones and slurry lines from abrasive wear.

A ceramic lining is not a purchase of tiles — it is a design decision about where the wear actually happens, how the tiles are held to the steel, and what happens at the joints. Get those three right and the lining outlives two or three sets of steel.

Where the failure really occurs

Most ceramic lining failures we are called to look at are not caused by the tile wearing out. They are caused by one of four things:

  • Corner spalling at the entry point. Particles strike the leading edge of the first tile. If the leading tile is not protected or chamfered, the whole bond line opens up.
  • Wear through the joints. A straight bond line lets a particle track straight down a gap. A staggered bond interrupts it.
  • Fixing failure, not tile failure. Adhesive that was not specified for the temperature; studs welded to a shell that was not clean; bolt heads worn proud of the tile surface.
  • Wrong grade for the impact. AL-99 tiles in a high-impact chute chip and break up far faster than AL-95, even though AL-99 is harder.

Four ways to hold a tile to steel

Method Best for Limits Relative cost
Weld-in studs Sections over 20 mm, high impact, temperature above 150 °C Requires a clean carbon-steel shell and welding access Low
Bolt-on plates Areas that need periodic replacement, access panels Bolt heads must be sunk below the tile face Medium
Epoxy adhesive Thin tiles, complex geometry, low temperature (under 100 °C) Not suitable for hot duty; surface preparation is critical Low
Ceramic-lined steel pipe Pipework, elbows and bends of any diameter Made as a composite unit, not field-installed Medium–high

What we supply

  • AL-92 / 95 / 99 mosaic and hexagonal tiles, 10–50 mm, in weld-in, bolt-on and adhesive versions
  • Lining bricks for mill shells, cyclone cones and thick-wall duty, mechanically keyed and curved to the shell
  • Ceramic-lined pipe, elbows, tees and reducers, DN50–DN600, backfilled into a steel body
  • ZTA tiles where edge chipping on a sharp installation is the limiting factor
  • Cutting, laying templates and installation guidance — our engineers will review your relining plan
Relining an existing piece of equipment?

Send us photographs of the worn surface and the shell dimensions. In most cases we can specify the tile layout and the fixing method without a site visit, and we will tell you whether the shell is reusable.

Tell us what the equipment handles, the particle size and the temperature, and we will propose a layout, grade and thickness.
