Iron, copper, gold, manganese and zinc ores are among the hardest and most abrasive feeds in the industry. Wear parts in mining circuits must survive heavy impact at the primary stage and abrasive slurry in grinding circuits, often on a 24-hour duty cycle.

Aggregate plants are the largest single market for crusher wear parts. Cost per ton of finished aggregate is decided almost entirely by how long jaw plates, cone liners and blow bars last between change-outs.

Cement plants combine abrasion-dominant wear with elevated temperature and almost no unplanned downtime tolerance. Shutdown windows are planned months in advance, so wear life has to be predictable as well as long.

Coal handling and pulverising equipment runs at high throughput with a mixture of impact and abrasion. Wear parts here are usually replaced on a schedule tied to unit outages, so consistency between batches matters as much as absolute wear life.

Recycling and demolition feeds are unpredictable by nature. Reinforcing bar, tramp metal and mixed material mean that toughness often matters more than maximum surface hardness, because a cracked blow bar stops the plant immediately.

Ground-engaging tools wear by sliding abrasion with intermittent high-impact loading. The right balance between work-hardening toughness and surface hardness decides both the wear rate and whether a tooth bends or snaps.
