Technical selection tables for chute liners and wear plates
Use these tables as a technical checklist before requesting chute liners, wear plates or processed liner parts. Final selection should be confirmed against drawings, material flow, impact load, existing liner life and installation constraints.
Hardness range reference
| Material option | Typical hardness reference | Practical use |
|---|---|---|
| NM400 wear plate | About 360-430 HBW | General abrasion protection and moderate-wear chute or hopper liner areas. |
| NM450 wear plate | About 420-480 HBW | Moderate-to-heavy abrasion in mining, cement and quarry transfer points. |
| NM500 wear plate | About 470-540 HBW | Severe sliding abrasion where the chute structure supports the liner correctly. |
| Ni-Hard / high chrome cast liner | Specified by casting grade and heat treatment | Severe abrasive flow zones where cast geometry or high cast hardness is preferred. |
Plate thickness range reference
| Thickness range | Typical liner use | RFQ note |
|---|---|---|
| 6-10 mm | Light-duty cover plates and low-impact sliding abrasion areas. | Confirm flatness, fixing pattern and minimum order quantity. |
| 12-20 mm | Common chute liner and hopper liner replacement plates. | Suitable for many bolt-on wear plate layouts. |
| 25-40 mm | Heavy-duty transfer points, crusher feed areas and higher-wear zones. | Check lifting weight, bolt access and installation clearance. |
| 50 mm and above | Severe wear or impact zones where structure and access allow thick liners. | Review drawing, support condition and replacement method before quotation. |
Material grade selection table
| Grade / liner type | Best-fit condition | Common buyer requirement |
|---|---|---|
| NM400 | Moderate abrasion with good workability and cost control. | Cut-to-size plates, standard bolt holes and general equipment liners. |
| NM450 | Higher abrasion while keeping practical processing and installation. | Mining chute liners, cement transfer liners and hopper liners. |
| NM500 | Severe sliding abrasion and high-wear transfer points. | Longer wear life, correct support and careful processing review. |
| ASTM A532 / Ni-Hard / high chrome cast liner | Severe abrasive flow or repeat cast liner shapes. | Grade confirmation, casting drawing, heat treatment and hardness inspection. |
Fixing method table
| Fixing method | Where it fits | Design notes |
|---|---|---|
| Bolt-on liners | Transfer chutes, hoppers and areas needing planned replacement. | Provide hole diameter, countersunk requirement, bolt spacing and access direction. |
| Weld-on liners | Fixed areas with lower replacement frequency. | Confirm welding procedure, preheating requirement and cracking risk for high-hardness plates. |
| Modular liner layout | Large chute surfaces with uneven wear patterns. | Use smaller replaceable sections to reduce spare cost and shutdown time. |
| Cast-in or machined cast liner features | Repeat cast wear liner parts and special geometry. | Confirm casting drawing, machining allowance and inspection standard. |
Wear mechanism vs material selection
| Dominant wear mechanism | Typical symptoms | Practical material direction |
|---|---|---|
| Sliding abrasion | Uniform thinning along material flow path. | NM450 or NM500 wear plate; cast high-hardness liner where geometry is suitable. |
| Impact abrasion | Cracking, broken edges, local deformation or fast wear at first contact point. | Review impact angle and support; use suitable NM grade, thickness and modular impact-zone layout. |
| Gouging / cutting wear | Deep scratches, grooves and sharp particle cutting marks. | Higher hardness wear plate or cast liner review, with thickness adjusted to service interval. |
| Material build-up | Blocked flow, changed trajectory and uneven liner wear. | Review chute geometry, liner layout, inspection access and surface transition gaps. |
| Fastener loosening | Plate movement, broken bolts or fines behind liner. | Improve bolt pattern, countersunk design, liner support and maintenance access. |
Standard RFQ Specification for NM500 Wear Plate
NM500 wear plate is mainly quoted as a drawing-based, cut-to-size and processed wear plate for severe sliding abrasion. The following ranges are practical quotation references; final selection depends on plate thickness, hole pattern, working temperature, impact load, installation method and buyer drawing.
NM500 specification reference
| Parameter | Quotation reference | RFQ confirmation required |
|---|---|---|
| Material grade | NM500 / 500-class abrasion-resistant steel plate, or buyer-specified equivalent grade. | Confirm requested standard, mill certificate requirement and whether equivalent grade is acceptable. |
| Hardness | Common 500-class reference: about 470-540 HBW. For many 4-32 mm wear plates, 470-530 HBW is a practical reference range. | State required hardness range, test position and whether hardness report is needed with shipment. |
| Thickness | Common chute liner range: 8-40 mm. Heavy-duty or long-life panels can be reviewed at 50 mm and above if structure and installation access allow. | Send existing liner thickness, target service life, panel weight limit and installation clearance. |
| Processing | Cut-to-size, drilled holes, countersunk holes, slots, edge chamfer, part marking and drawing-based inspection. | Provide DXF/PDF drawing, hole coordinates, countersink requirement, tolerance and part number list. |
| Fixing method | Bolt-on, countersunk bolt, welded support area or modular liner layout depending on chute access and replacement plan. | Confirm bolt size, bolt direction, access door position and whether welding is allowed on site. |
Price and quotation factors
| Factor | Why it matters | What to send |
|---|---|---|
| Plate thickness and weight | NM500 pricing is strongly affected by tonnage, thickness availability and cutting yield. | Thickness, size, quantity and destination country. |
| Hole pattern and machining | Drilling, countersinking and slotting high-hardness plate increases processing time and tool cost. | Hole table, coordinates, hole diameter, countersink angle/depth and tolerance. |
| Impact and abrasion condition | NM500 is strong for severe abrasion, but high impact may require thickness, support or material review. | Material handled, particle size, drop height, current wear failure photos and existing liner life. |
| Batch size | Trial sets, urgent replacements and repeat annual batches have different setup and purchasing costs. | Trial quantity, annual usage, spare list and whether repeat drawings are expected. |
| Inspection and packing | Marked part numbers, dimensional inspection, hardness reference and export packing affect schedule and cost. | Inspection report requirement, packing method, pallet weight limit and installation sequence labels. |
MOQ, lead time and documents
| Item | Planning reference | Notes |
|---|---|---|
| MOQ | Sample or trial liner sets can be reviewed by drawing. Economic batch quotation is usually better from about 500 kg to 1 metric ton and above. | Small urgent replacement parts can still be evaluated when drawings and thickness are clear. |
| Lead time | Typical processed NM500 wear plate order: about 15-30 working days after drawing confirmation and deposit. | Lead time depends on plate stock, thickness, cutting workload, hole count, inspection and packing. |
| Inspection documents | Material certificate, hardness reference, dimension inspection photos/report and packing photos can be supplied according to project requirement. | State document requirements before quotation. |
| Packing and marking | Export pallet/crate packing, rust protection, drawing number, part number and installation sequence labels. | Useful for modular chute liner sets and shutdown replacement planning. |
