Description
Bolt-On Chute Liner Plates for Fast Replacement and Drawing-Based RFQ
Bolt-On Chute Liner Plates are replaceable wear panels for transfer chutes, hoppers, bins, crusher feed areas and conveyor discharge points. They are used when a plant wants shorter shutdown time, predictable spare parts and easier liner replacement than fully welded wear plates.
EB Chute Liner supplies bolt-on liner plates from drawings, photos or measured samples. Plates can be quoted in NM400, NM450, NM500 or alternative wear-resistant materials, with drilled holes, countersunk holes, slots, edge preparation, part marking and export packing.
Where bolt-on liners fit
Planned shutdown replacement
Use bolt-on panels where maintenance teams need to remove worn liners quickly without cutting or gouging old welds.

Chute and hopper wear zones
Suitable for sliding abrasion, moderate impact zones, material build-up areas and replaceable liner sections.

Drawing-controlled hole pattern
Hole diameter, pitch, edge distance, countersink and bolt-head clearance should be confirmed from the drawing.

Spare parts strategy
Panels can be marked by part number or installation position so plants can keep high-wear sections in stock.

Standard RFQ Specification for Bolt-On Chute Liner Plates
The table below can be used as a starting specification when requesting bolt-on liner plates. Final quotation depends on drawing revision, material grade, thickness, hole processing, quantity, inspection and packing requirements.
Recommended specification range
| Item | Quotation reference | Buyer should confirm |
|---|---|---|
| Material grade | NM400, NM450, NM500 or equivalent wear-resistant steel; high chrome or composite alternatives can be reviewed for special applications. | Existing liner material, handled material, target service life, impact level and whether equivalent grade is acceptable. |
| Hardness range | Reference only: NM400 about 360-430 HBW, NM450 about 420-480 HBW, NM500 about 470-540 HBW. | Required hardness band, certificate format and whether toughness or abrasion resistance is the priority. |
| Thickness range | Common chute and hopper liner range: 8-50 mm; heavier impact zones or special drawings can be reviewed separately. | Current liner thickness, allowable weight, bolt length and space behind the liner. |
| Hole pattern | Through holes, slots, countersunk holes, staggered hole rows or modular panel hole layouts. | Bolt size, hole diameter, pitch, edge distance, countersink angle/depth and hole tolerance. |
| Panel shape | Flat plate, segmented panel, curved layout by drawing, chamfered edge or marked installation position. | Drawing number, part ID, left/right orientation, bend direction and installation sequence. |
| Surface and edge | As-cut, deburred, chamfered, marked, painted edge or packed with rust protection as required. | Any paint, marking, edge preparation or rust-prevention requirement before shipment. |
Quote factors and price basis
| Price factor | Why it changes cost | RFQ note |
|---|---|---|
| Material and thickness | Higher hardness and thicker plates increase material weight, cutting time and drilling difficulty. | Send grade, thickness and total plate quantity. |
| Hole count and tolerance | Every hole or slot adds drilling, countersinking and inspection time. | Provide a hole table or dimensioned drawing instead of only photos. |
| Panel size and nesting | Large or irregular panels can change plate yield and scrap rate. | Send DXF/DWG if available for nesting review. |
| Inspection documents | Hardness reports, dimensional reports and packing photos require extra QC steps. | State required documents before quotation. |
| Packing and delivery | Export crates, steel pallets, part labels and destination affect packing cost. | Confirm destination country, gross weight limit and unloading method. |
MOQ, lead time and document planning
| Item | Typical planning reference | Notes |
|---|---|---|
| MOQ | Trial quantities can be reviewed by drawing; better unit cost usually starts from batch or full liner-set orders. | Send piece count per drawing and total weight if known. |
| Lead time | Common processed liner orders are often planned around 15-30 working days after drawing confirmation and deposit. | Lead time depends on grade availability, thickness, hole count and inspection level. |
| Drawings | PDF, DWG, DXF, STEP, sketch or measured photos can be used for initial review. | CAD files are preferred for hole coordinates and repeat orders. |
| Documents | Material certificate, hardness check, dimensional inspection photos and packing photos can be supplied when required. | Confirm required documents before production. |
Bolt-on vs weld-on vs countersunk fixing
| Fixing method | Best use | RFQ detail to send |
|---|---|---|
| Bolt-on liner plate | Fast replacement, planned shutdowns and areas where rear access or threaded inserts are available. | Bolt size, hole pitch, access direction and plate thickness. |
| Countersunk bolt wear plate | Flush material-flow surface where exposed bolt heads may wear or disturb flow. | Countersink angle, head diameter, countersink depth and remaining thickness. |
| Weld-on liner plate | Fixed liner sections where replacement is less frequent or bolting is not practical. | Welding procedure, preheat requirement, access and crack-control expectations. |
| Plug weld hole plate | Attachment to backing structure where through bolting is difficult. | Plug weld hole diameter, pitch, weld side and grinding requirement. |
