Wear liners for hoppers, transitions, chutes, and spouts in material handling systems are available in several types to handle different forms of abrasive wear. After classifying forms of abrasive wear, this article describes wear liner types, including their advantages and disadvantages, and tips for selecting and installing a liner.
