CONVEYOR SELECTION GUIDE
Choosing the right industrial conveyor for your application starts with understanding what you need to move, how much material or product must travel, and how the conveyor will fit into your process. An unsuitable conveyor can complicate transfers, maintenance and production flow even when it appears capable of moving the load.
This guide explains the major conveyor categories offered by Saturn Conveyor, how they work, and the engineering questions worth answering before selecting equipment.
Understanding Industrial Conveyor Selection
Industrial conveyors transport bulk solids, discrete products or unit loads between points in a facility. The correct equipment depends on the physical characteristics of the conveyed material or load, required capacity, route geometry, operating environment and upstream and downstream machinery.
A dry powder behaves very differently from a sealed carton or a loaded wooden pallet. Accordingly, bulk material conveyors and unit-load conveyors use different conveying mechanisms and require different design considerations.
How Different Conveyor Systems Work
Belt Conveyors
A belt conveyor uses a moving belt supported by rollers or a slider bed to carry suitable products along a defined path. Belt width, speed, load support, tracking, transfer points and cleaning requirements should be reviewed for each application. Explore belt conveyors.
Chain Drag Conveyors
Chain drag conveyors use moving chain and flights within a trough or enclosure to transport suitable bulk solids. Material characteristics, chain speed, enclosure design, inlet and outlet arrangement, and wear considerations influence selection. Explore chain drag conveyors.
Screw Conveyors
Screw conveyors use a rotating helical flight within a trough or tube to move suitable bulk materials. Capacity depends on factors including screw geometry, rotational speed, material properties and inclination. The suitability of a screw conveyor for a particular product must be evaluated, especially when the material is abrasive, fragile, cohesive or difficult to flow. Explore screw conveyors.
Flexible Screw Conveyors
Flexible screw conveyors typically use a rotating flexible spiral inside a tube to convey suitable dry bulk materials. They may offer useful routing options in some plant layouts, but performance depends on material behavior, tube geometry, routing and operating duty. Explore flexible screw conveyors.
Pallet Conveyors
Powered pallet conveyors support and move unit loads on pallets. Chain-driven live roller (CDLR) conveyors and chain strand conveyors differ in how they support and drive a pallet. Pallet construction, bottom-board orientation, load distribution and transfer geometry are important selection factors. Turntables may be used when a pallet needs to change orientation or travel direction. Explore pallet conveying equipment.
Common Industrial Applications
Moving Dry Bulk Materials
Powders, granules and other suitable dry bulk products may be transported between storage, feeding, mixing and processing operations. Flow behavior, dust management, product degradation, cleanability and inlet or discharge conditions can determine which conveying method is appropriate.
Conveying Cartons and Packaged Products
Manufacturing and packaging lines often need predictable movement of boxes, cartons or individual products. Product dimensions, weight, base stability, spacing, transfer points and line speed are important factors when considering a belt conveyor.
Moving Loaded and Empty Pallets
Loaded pallet conveyors can connect production, palletizing, storage and dispatch operations. Empty pallet conveying may be combined with dispensers or stackers to support pallet supply and recovery. Pallet dimensions, bottom construction, weight range and transfer direction must be confirmed.
Key Benefits and Engineering Considerations
- Throughput and capacity: Define the required rate in appropriate units, such as mass per hour, packages per minute or pallets per hour. Include peak demand and operating duty.
- Dust control and housekeeping: For dusty bulk materials, consider enclosure design, transfer points, extraction needs and cleaning procedures.
- Product handling: Evaluate fragility, abrasion, moisture sensitivity, flow behavior and potential for buildup or damage.
- Integration and maintenance: Confirm loading and discharge arrangements, access for servicing, guarding, controls, interlocks and interfaces with adjacent equipment.
Comparing Conveyor Options
| Conveyor type | Typical handling focus | Key selection considerations |
|---|---|---|
| Belt | Suitable discrete products and packages | Product base, width, speed, transfers and belt compatibility |
| Chain drag | Suitable dry bulk solids | Material flow, wear, enclosure and routing |
| Screw | Suitable dry bulk solids | Material behavior, geometry, inclination and duty |
| Flexible screw | Suitable powders and granules | Material suitability, routing, tube and spiral configuration |
| Pallet | Loaded or empty pallets | Pallet construction, weight, support and transfers |
These are general application distinctions, not performance rankings. Detailed suitability must be confirmed for the specific duty.
How to Select the Right Industrial Conveyor
Begin by documenting the actual load and the required material flow. A useful preliminary specification should include the material or product description, dimensions or bulk density, required capacity, conveyor distance, elevation changes, plant layout, environmental conditions and relevant safety or sanitation requirements.
Questions to Ask Before Specifying Equipment
- What exactly is being conveyed, and what are its physical and handling characteristics?
- What is the average and peak required throughput?
- What route, transfers and elevation changes are required?
- How will the conveyor connect to upstream and downstream equipment?
- What cleaning, guarding, operator access and maintenance provisions are needed?
Frequently Asked Questions
Which conveyor is best for powders and granules?
There is no universal best option. Chain drag, screw and flexible screw conveyors may each be suitable for certain dry bulk materials. Flow properties, capacity, distance, routing and process constraints determine which should be evaluated.
Can the same conveyor handle both loaded and empty pallets?
Potentially, if the equipment is designed for the full range of pallet dimensions, weights, construction and support requirements. Empty pallets may also require dedicated dispensing, stacking or transfer equipment.
What information is needed for a conveyor quotation?
Provide the material or load description, required capacity, travel distance, layout, loading and discharge details, operating environment and any available drawings or equipment interface information.

Conclusion
The right industrial conveyor is selected by evaluating the complete conveying duty, not just the equipment name. Material characteristics, throughput, layout, transfer requirements and maintenance considerations all influence the final design. Comparing suitable conveyor technologies against those requirements is the most reliable starting point.
