Overland Conveyor Design Checklist is a practical buyer guide for coal mining, coal handling, and preparation plant teams comparing equipment options, technical specifications, related systems, and RFQ requirements.
Buyer summary
Overland Conveyor Design Checklist is written for mine operators, EPC teams, plant engineers, and procurement teams that need to compare equipment options before sending a supplier RFQ. The goal is to define the process duty clearly enough that suppliers can size equipment, select wear materials, and quote the required controls, guards, and spare parts without guessing.
Where this guide applies
long-distance coal conveying between pits, plants, stockyards, ports, and power stations is usually part of a wider coal handling or coal preparation flowsheet. Buyers should not evaluate it as a standalone item only. The upstream feed condition, downstream receiving equipment, available layout, maintenance access, and dust or slurry conditions all affect the final specification.
Equipment and process scope
Typical equipment scope includes overland conveyors, drive stations, take-up systems, idlers, pulleys, belts, transfer towers, maintenance walkways, and monitoring systems. In many projects, the main equipment price is only one part of the decision. Chutes, liners, platforms, guards, instrumentation, drives, local control panels, and spare parts often determine whether the installed system performs reliably after commissioning.
Specifications buyers should compare
| Specification area | What to define before RFQ |
|---|---|
| Capacity | Nominal tph, peak tph, utilization factor, and expected operating hours. |
| Material condition | route length, lift profile, horizontal curves, belt speed, lump size, capacity, weather exposure, and required availability |
| Installation environment | Indoor or outdoor location, ambient temperature, dust load, access space, and corrosion conditions. |
| Maintenance access | Inspection points, wear-part removal space, lifting access, shutdown windows, and spare part strategy. |
| Controls and safety | Interlocks, local isolation, guarding, emergency stops, sensors, and site electrical standards. |
Common RFQ mistakes
A long conveyor cannot be budgeted reliably from length and capacity alone. Route geometry, lift, starting conditions, belt rating, and transfer points change the engineering scope.
- Asking for a budget price without feed size, moisture, capacity, or layout.
- Comparing suppliers without confirming the same duty point and scope boundary.
- Ignoring transfer points, access platforms, dust control, or wear liners until late in the project.
- Requesting only the main machine and forgetting commissioning spares and critical wear parts.
RFQ information to prepare
Prepare route survey, elevation profile, capacity, lump size, belt width preference, transfer points, maintenance access, electrical supply, and environmental restrictions.
A strong RFQ should also include drawings or layout sketches, preferred standards, destination country, site voltage, operating schedule, and any restrictions on height, footprint, noise, dust, or water use.
Related equipment and next steps
After defining the process duty, compare the related equipment around the same process step: coal conveyor systems, conveyor belts, idlers, belt cleaners, transfer chutes, and stockyard equipment. This helps suppliers understand the complete system boundary and reduces quotation gaps between mechanical equipment, electrical controls, and site installation.
