For replaceable wear plates in bins, chutes, feed and discharge areas, feeders, screen boxes and equipment housings. Consider abrasion, drop impact, thickness, support, low temperatures, cutting, bending and welding together.
Controlled heat treatment gives quenched and tempered wear plate a combination of hardness, strength and toughness. It suits protective parts made by cutting, drilling, bending or welding plate. Its manufacturing route differs from cast manganese steel, chrome-moly liners and high-chromium iron; hardness alone does not establish interchangeability.
Primarily for replaceable wear protection fabricated from steel plate.
Check support and toughness where large lumps fall from height. For sticky material, compare low-friction options such as UHMWPE.
Load-bearing screen box plates and replaceable wear plates have different functions; wear plate must not replace structural steel without an engineering assessment.
High-speed blow bars, mantles, concaves and primary load-bearing housings require their own specifications; the term wear plate does not establish suitability.
The same plate can have markedly different service lives in different locations. Match the material to both the wear mechanism and the supporting structure.
| Part / Position | Conditions and Common Failures | Required Material Properties | Fabrication and Selection Requirements |
|---|---|---|---|
| Transfer Chute Liners | Sliding particles, erosion, local drop impact and curled edges. | A balance of wear resistance and fracture toughness, consistent through-thickness hardness and good surface quality. | Impact angle, drop height, plate dimensions, mounting holes, overlap direction, backing support and replacement access. |
| Bin / Feed Hopper Liners | Large falling lumps, compression, sticking, stress around holes and temperature changes. | Impact and wear resistance and low-temperature properties; assess friction where sticking is severe. | Select materials separately for the initial impact and sliding zones; check bolted or welded fastening and thermal expansion. |
| Apron Feeder Side Liners and Impact Plates | Ore impact, scraping, vibration near pans and wear at clearances. | Toughness, wear resistance, dimensional stability and crack resistance around holes. | Clearance to pans and sprockets, plate thickness, countersunk holes, support and assembly direction. |
| Screen Box and Housing Protection Plates | Fine particle erosion, vibration, loose bolts and edge fatigue. | Wear resistance, flatness and sufficient fatigue resistance. | Distinguish structural plates from replaceable liners; control hole positions, edge distances, mass and welding distortion. |
| Feed and Discharge Protection Plates | Concentrated particle impact, changes in flow direction, local erosion and wear-through. | Impact toughness, wear resistance and ease of replacement. | Flow direction, stream width, thinnest worn area, fastening method and fit with adjacent parts. |
Retaining the supplied plate properties requires suitable cutting, cold or hot forming, welding and fastening procedures.
Check grade, heat or batch identification, thickness, delivery condition, hardness and impact requirements; a trade name is not a generic steel grade.
Control the heat-affected zone, hole edge quality and microcracking. Select drilling, countersinking or waterjet cutting from the material data.
Follow the requirements for plate thickness, hardness level, bending direction and minimum radius; control preheat, heat input and hydrogen cracking risk.
Check flatness, hole spacing, edges, plate overlaps, bolt preload and backing contact to avoid unsupported areas exposed to impact.
Review the equipment position to confirm dimensions, drawing numbers and replacement methods.
