  • Liner Wear Plate Selection for Chutes bulkonline Forums

    There can be two types of wear in a chute, abrasion wear and impact wear. Abrasion wear ususally occurs when the material slides along the wear liner material and impact abrasion is when the conveyed material strikes the wearliner at oblique angles. One or both types of wear may be present in a chute.
