From theerasak phadungsri of dimet (siam)public co.,ltd. on March 24, 2012:
     You have to check speed of abrasive and design.

From M Ehab of North Valley on March 21, 2012:
   Epoxy coating reinforced with glass flakes with glass flake contents by weight in dry film not less then 25%.

From bart de cremer of acotec nv on January 17, 2012:
 We believe that a solvent-free, modified, polyamine-cured epoxy with an anti-abrasive filler is a perfect solution.

From Rodolfo Castro of International paint (Akzo Nobel Chile) Ltda on January 10, 2012:
     We usually work with solid polyurethane linings (12 mm thickness) for the interior of pipelines with copper slurry tails and concentrates. You can see some solutions in www.acotec.cl.

From Hanif Khairul of Hempel A/S on November 1, 2011:
As far as I know, the  answer is an abrasive-resistant epoxy. Some phenolic type with hard filler will also fulfill  this purpose. However, if the flow of material is a concern, a low-friction coating like fluoropolymer is better.

From Kishore Kumar K R of Nukote on November 4, 2011:
Highly abrasion-resistant polyurea is the best among the current polymers.

From Roy Bradley of Laing O'Rourke on November 3, 2011:
     You may like to consider a chloro-sulphonated polyethylene for a trial. Hypalon is a trade name (I believe).
