Description
Drawing-based liner plates for ore transfer chutes exposed to impact, sliding abrasion, build-up and concentrated wear.
Ore transfer chute liner plates protect the chute shell and replaceable internal flow surfaces at conveyor transfers, crusher feeds, reclaim systems and mineral-processing plants. Panels are manufactured to approved drawings, material grades, thicknesses and fixing details rather than sold as a universal one-size liner.
Useful selection data include ore type, maximum lump, moisture, throughput, drop height, impact direction, belt speed and the wear history of each chute zone.
Impact and abrasion zones
Different materials or thicknesses can be assigned to direct-impact, sliding and lower-wear areas.
Custom plate geometry
Flat, bent, curved and tapered panels can be produced with drawing-controlled holes and fixing features.
Replacement planning
Stable part IDs, liner maps and zone-based packing support shutdown preparation and repeat orders.

Typical ore transfer chute applications
- Primary and secondary crusher feed or discharge chutes.
- Conveyor-to-conveyor transfer points in surface and underground mines.
- Ore stockpile reclaim and feeder discharge transitions.
- Screen, surge-bin and hopper feed chutes.
- Deflector plates, impact walls and changes in material-flow direction.
- Replacement liner panels for existing mining chute assemblies.
For a broader transfer-point product, see Conveyor Transfer Point Wear Liners. This page focuses on ore-handling duty and the RFQ information needed to manufacture replacement plates.
Operating conditions that control liner selection
| Condition | What to provide | Why it matters |
|---|---|---|
| Ore and mineralogy | Ore type, hardness, abrasiveness and significant contaminants. | Provides context for wear mechanism and material comparison. |
| Lump size | Typical distribution and maximum credible lump. | Influences impact severity, local support and panel-joint exposure. |
| Moisture and fines | Normal and seasonal range, clay content and build-up history. | Affects friction, adhesion, flow behavior and cleanout frequency. |
| Throughput | Normal, peak and surge feed rates. | Defines exposure and helps separate capacity problems from liner problems. |
| Trajectory | Belt speeds, drop height, impact angle and direction change. | Identifies high-energy zones and likely wear concentration. |
| Service history | Remaining thickness map, hours, failure mode and replaced part IDs. | Supports differentiated materials and practical spare quantities. |
Why ore contact behavior matters
Transfer chute performance depends on more than nominal liner hardness. Moist ore fines can interact differently with cast iron, ceramic or steel surfaces, while belt speed and chute geometry alter the impact and sliding conditions. Published transfer-chute research uses controlled tests and DEM calibration to understand these interactions; a commercial replacement RFQ should still rely on the buyer’s actual operating data, approved design and wear records.
Material-flow testing does not certify a finished liner product. It illustrates why ore condition, surface interaction and trajectory should be considered together instead of choosing a grade only from a hardness number.
Material options for ore chute liner plates
| Material family | Typical use consideration | Checks before approval |
|---|---|---|
| NM400 / NM450 wear plate | Fabricated panels requiring a balance of abrasion resistance, formability and toughness. | Thickness, bend direction, heat input, fixing method and temperature. |
| NM500 wear plate | Higher nominal hardness for severe sliding abrasion where forming and impact demands are suitable. | Impact severity, fabrication route, hole preparation and support flatness. |
| High-chrome cast iron | Severe abrasive zones where a cast geometry and the impact environment are compatible. | Impact energy, casting section, backing support, attachment and handling. |
| Buyer-specified alloy or mixed layout | Existing plant standards or zone-specific combinations. | Complete specification, substitutions, transitions, traceability and acceptance criteria. |

Available geometry and fixing features
Ore transfer chute liners can be supplied as flat, bent, tapered or curved parts. Drawing-controlled preparation can include round holes, slots, countersinks, keyhole slots, plug-weld holes or rear studs when the complete installation method is defined.
- Flat replaceable panels for straight chute walls and skirt zones.
- Bent and curved liners for transitions, corners and flow-controlling profiles.
- Deflector plates and impact-zone liners with project-specific support.
- Modular high-wear panels for targeted replacement.
- Matched part sets with wear face, flow direction and installation position marked.

Liner layout and replacement details
| Design item | Practical requirement |
|---|---|
| Panel joints | Avoid avoidable ledges facing the incoming flow; define overlap and joint direction on the drawing. |
| Fastener profile | Control projections, counterbores or recesses that affect wear and material flow. |
| Support condition | Record shell flatness, backing gaps and local repairs before copying an old panel. |
| Part identification | Use unique IDs for location, orientation, mirrored parts and revision. |
| Wear zoning | Separate direct-impact, sliding and low-wear regions when service history supports it. |
| Removal access | Confirm rear access, lifting arrangement, panel sequence and shutdown constraints. |

Manufacturing and inspection scope
The manufacturing route follows the approved drawing and material specification. Scope may include profile cutting, drilling, countersinking, forming, machining, casting, stud attachment and permanent part marking. Inspection points should focus on features that affect fit, orientation and traceability.
- Material grade and thickness verification.
- Outline, datums, hole centers, bend angle and curvature checks.
- Wear-face, shell-side and material-flow marking.
- Part ID and drawing-revision traceability.
- BOM reconciliation and shutdown-sequence packing.
Buyers can define the records using the Chute Liner Inspection Checklist Before Shipment.
