Not all manganese steel or alloy hammer parts perform equally. A liner that lasts well on limestone may wear out rapidly on hard, silica-rich granite. Wear rate directly controls operating cost and scheduled downtime.

Abrasive wear testing measures material loss under simulated feed conditions. It compares impact resistance and abrasive scratching to match the right alloy to each rock type.

SMP wear part technicians run wear assessments based on customer ore samples. They recommend high-manganese, chromium alloy or composite hammers according to abrasion index and impact energy.

Selecting wear parts by abrasion test data lowers tonnage-based wear cost and extends service intervals between liner changes.
