Re: Ceramic Liners Vs. Metal Liners
This is the closest thing I have seen in the public domain:

Suspect a lot of it is based on empirical reserach within group / industry / site.
Ceramics (poor fracture toughness) do not respond well to tramp (metal or larger rock present in ROM etc).

Metal Liners Vs. Ceramic Plating
Dear Kayem,
when doing design I always look after life cycle cost vs. primar investment sum. Several square meters of some wear plate can easily be flame cut into size and welded (or bolted) to the chute walls.
In general metal liners resist better against impact, when ceramic based lining has good resistance to wear / flow friction. So you look after free fall heigths in your loading points.
There's not always a throughput that big as in Richards Bay, and in more remote areas some metal lining is rather easier to obtain ( and to maintain ) than hightech ceramic / rubber liner equipment.
But sometimes, when conveying of sticky goods is on the agenda, I even prefer rubber liner bars at baffle plates. So the baked up conglomerates break and fall down as the rubber gives way to impact forces.
Hope I could give you some useful hint.

Metal Vs Ceramic Liners
Dear Mr. Kayem,
We have been supplying ceramic liners for over a decade.
One of the critical applications of ceramic is in the material charging hoppers of a steel plant. We have been successfully supplying and applying ceramics for this application.
For the highest impact zones we recommend 50 mm ceramic liners which are pasted onto the steel casing by means of a high temperature adhesive. For moderate and low impact areas we recommend 25 mm and 13 mm liners respectively. The joints between the 50 to 25 and 13 mm are carefully pre-engineered so that there is a smooth transition.
The ceramics have given 7 years life at one such installation at a reputed steel plant in India.
The selection of material for impact application is done based on a carefull study of the operating parameters such as fall height, temperature, dry or wet application, particle size, nature of material being transferred or conveyed etc.
The major USP's of ceramic are
Good abrasion and corrosion resistance.
Temperature resistance upto 1700 degree celsius.
High surface finish which is a contributing factor to its non-stick property along with its zero water absorption property.
Moderate impact resistance.

Ceramic Liner Vs Metal Liners
Dear Kayem
*Ceramic Liners directly fixed on mother plate of pipes, chutes, bends in non impact area of material handling is widely used in Industry particularly in Thermal Power Stations for conveying fine abbressive coal etc
*Ceramic Composite Liners (Embaded /Impregnated in Polymers, Rubber, PolyUrethane etc) etc have got techo Commercial advantages (Corrosion resistance, High Wear restistant, Flow Promotion etc) over conventional metalic liners
*We are manufacturing these Ceramic Composite Liners for various applications
*We will be to happy to suggest appropriate Composite on receipt of your specific application detail ■

Ceramic Liners Vs. Metal Liners
It seems, from most of the postings here, that Ceramic liners (preferably tiles mounted on rubber) are preferred over conventional metal liners including SS liners.
Is there any documented study / case study which proves that such ceramic liners actually outlast SS liners in operation ? I would be most interested in reading any such article.
Under what circumstances would metal liners be preferred over ceramic liners & why ? Could someone please enlighten me on this ?
Thanks
Kayem ■
