Dear Mr. Wolfgang,

The choice of liners is affected by:

1) Impact resistance i.e. liner should not break down.

2) Wear resistance i.e. it should have acceptable life

3) Flowability of material on liner.

4) Ease / difficulty of installation

5) Ease / difficulty of maintenance i.e. quick availability, stock and replacement

6) Over all economy considering all above aspects.

I suggest you to write to manufacturers of the liners mentioned by you, requesting to send technical / application data / information. Often their sales literatures do include comparative data (I have seen such data). You will need to arrive at your conclusion after comparing the data from various sources. Such data can best be created by the manufacturers or user of plant, after sufficient field tests and experience.

Because wear is such a complex phenomenon, it is difficult to summarise it in a single table. The table referred to above provides a good summary of some experience with wet sliding abrasion.

Dry sliding abrasion will provide a slightly different set of results, since there will not be a corrosion component.

Impact situations will give a different ranking again as will slurry wear. Intensity of the wear action will also influence rankings, as will the angle of attack. The effect of grain size in the wear material will be influenced by the grain size in the abrasive ore.

I have seen some good guidelines developed for the selection of wear materials, but these considered a range of different wear situations. I think you might find a similar approach to be helpful.
