... vanes push the particle-laden fluid into various passages. The inside of tubes or pipes is often damaged at curves because the inertia of the particles and the fluid forces them against the outer side of the curve. Obviously, sudden, sharp curves or bends cause more erosion problems than gentle curves...

The first of these arrangements makes use of a motor running at constant speed to rotate one of the parts as it is driven into contact with the second, stationary part. The resulting friction and abrasion heats...
