Start with the material and operating duty
Describe the material at the point it enters the conveyor, not only its name. Particle size and shape, bulk density, moisture, flow behaviour, abrasiveness, fragility and dustiness all affect the way it can be fed, contained and transferred.
Then define the duty over a normal operating cycle. Include the required rate, whether feed is continuous or batch-based, start-stop frequency, operating hours and what happens during upstream surges or downstream stoppages. The conveyor has to fit the process around it, not just move material between two points.
Map the route, including horizontal distance, changes in direction, elevation, transfer points and available headroom. The same material may need different equipment for a short connection, vertical lift or long transfer route.
- Bulk material or packaged unit loads
- Product condition, including moisture, size range, fragility and dust
- Required operating rate and expected feed pattern
- Route, elevation, loading and discharge points
- Cleaning, containment, access and environmental requirements
Compare conveyor types by the job they do
Use the comparison as a first screen, not as a final specification. Final selection depends on the actual product, transfer arrangement, operating profile and plant constraints.
| Conveyor type | Often considered for | Key tradeoff to assess |
|---|---|---|
| Belt conveyor | Continuous movement of bulk material or packaged product along a defined route | Needs suitable loading, belt support and transfer design; incline suitability depends on the product and belt profile |
| Screw conveyor | Compact horizontal or mildly inclined transfer of fine, granular or sticky material | Enclosed, low-profile arrangement can suit tight spaces, but product behaviour and conveying duty must be checked |
| Drag chain conveyor | Enclosed transfer of dusty, abrasive or fine bulk material | Containment is useful, while chain, trough and material compatibility need to be considered together |
| Bucket elevator | Vertical elevation of grain, seed and granular material where floor area is limited | A compact vertical route requires suitable feed, discharge and attention to product damage and dust |
| Vibratory conveyor | Feeding, spreading or conveying product gently across a deck | Useful for controlled distribution, but the product and required conveying action must suit vibration |
| Swing tray bucket elevator | Vertical handling where gentle discharge is important for fragile or valuable product | Gentle handling can matter more than choosing a conventional high-throughput elevator arrangement |

Design the interfaces, not just the conveyor
A conveyor is one part of a handling route. Check how material is metered onto it, how it transfers at the head and tail, and whether downstream equipment can accept the flow. Transfer points, chutes, hoppers and intermediate storage can affect spillage, blockages, dust and product damage.
Consider access for inspection, cleaning and maintenance while the layout is still flexible. For food or agricultural products, confirm the required contact material and cleaning approach. Facet Engineering lists mild steel, galvanised steel and stainless steel as available conveyor construction materials; the suitable choice depends on the application and environment.
Include conveyor trapping points, guarding and safe access for cleaning and maintenance in the application risk review. Grain handling also calls for attention to combustible dust, ignition sources and safe isolation during maintenance. The UK and US reference guidance below is not a substitute for a site-specific risk assessment or applicable local regulations.
Where a conveyor feeds a process line, coordinate its operating rate and controls with the receiving machine and the rest of the line. A nominal machine rate does not by itself prove that the complete system will achieve the required output.

What can and cannot be decided before application review
A preliminary equipment family can often be identified from the material and route, but capacity, dimensions, drive selection, construction details and final configuration are application-specific. They need to be confirmed against the operating duty, product properties and layout.
When requesting a proposal, provide a route drawing or sketch and describe the connection points. If the application is part of a larger processing line, share the surrounding process steps as well as the conveyor requirement.
Conveyor selection information to prepare
- Material name, physical condition, particle size and bulk density if known
- Moisture, abrasiveness, dust, fragility and any contamination or hygiene concerns
- Required conveying rate, operating pattern and expected surges or interruptions
- Route sketch with distance, elevation, direction changes and transfer points
- Feed source, receiving equipment and available buffer or storage
- Operating hours, cleaning needs, maintenance access and site environment
- Preferred construction material, controls and any existing equipment interfaces
Common questions
- Which conveyor is best for grain?
- There is no single best conveyor for every grain duty. Belt, screw, drag chain and bucket elevators each suit different routes and handling requirements, so selection depends on the grain condition, transfer route, required rate and plant layout.
- What information is needed to size a conveyor?
- Provide material properties, required operating rate, feed pattern, route dimensions and elevation, loading and discharge details, and site conditions. Capacity and equipment selection must be confirmed for the specific application.
- When should I use a bucket elevator instead of a belt conveyor?
- A bucket elevator is commonly considered when grain or granular material needs vertical elevation in a compact floor area. A belt conveyor is considered for movement along a defined horizontal or inclined route. The final choice depends on product, route and transfer design.
- How do I convey fragile seed or product?
- Identify where damage occurs and review the entire route, including loading, transfer and discharge points. Facet Engineering lists swing tray bucket elevators for gentle discharge and low-damage seed handling systems, but the right arrangement depends on the product and process.
- Can I choose the conveyor before the plant layout is final?
- You can identify candidate conveyor types early, but route, elevation, transfer points and access affect final configuration. Share the current layout and expected changes so the equipment can be assessed against the real plant interfaces.
