Absorbs falling ROM ore impacts and protects the feed hopper steelwork.
Feed Hopper Liners (Feed Hopper Liner)— Gyratory Crusher Wear part, position 33.
| Installation Position | Inside the feed hopper above the crusher; outside positions 01–30 in the FLS crusher section. |
| Main Function | Absorbs falling ROM ore impacts and protects the feed hopper steelwork. |
| Replacement Frequency | High replacement frequency; assess remaining thickness, cracks, looseness, perforation and uneven material flow. |
| Item | Details |
|---|---|
| Material Options | Quenched and tempered wear plate in the 400–500 HB range, bimetallic overlay plate, ceramic composite or rubber liners |
| Typical Properties and Acceptance Criteria | Material selection depends on lump impact and drop height, sliding distance, ore abrasiveness and blockage risk. Prioritise core toughness and replaceable modules in high-impact zones. In predominantly sliding zones, higher surface hardness or composite options may be suitable. Acceptance checks also cover plate thickness, bolts, joints, support and flow path geometry. |
| Principal Failure Mechanism | Sliding or three-body abrasion, localized impact and cracking around fastener holes |
