Frequently Asked Questions About The Aggregate Industry: Wear-Resistant Solutions

  • What causes excessive wear in aggregate processing equipment?

    Aggregate processing equipment experiences severe wear from continuous handling of abrasive materials such as crushed stone, gravel, sand, and mineral particles.


    Common wear mechanisms include:

    • Sliding abrasion from hard aggregate particles
    • High-impact loading at transfer points
    • Gouging abrasion from large rocks
    • Particle erosion in cyclones and fans
    • Continuous mechanical loading
    • Improper material flow
    • Inadequate wear-resistant materials

    High-wear components include crusher liners, screens, hammers, chutes, hoppers, washing equipment, and mobile machinery.


    SAS Global Corporation manufactures premium wear-resistant materials and custom-engineered components designed to reduce premature deterioration and extend equipment service life.

  • What are the best wear-resistant materials for aggregate processing equipment?

    The best wear-resistant material depends on the equipment, aggregate hardness, impact loading, and severity of abrasion.


    Common materials include chromium carbide overlay plate, complex carbide overlay plate, abrasion-resistant alloy steel, and manganese steel.


    SAS Global offers several premium materials:
