Conveyor Types and Their Applications Across Industries
Choosing the right conveyor system is crucial for improving productivity, ensuring safety, and optimizing material flow. Below is a comprehensive guide to the most common types of conveyor systems and where they are best applied across different industries.
1. Belt Conveyor
Description: A continuous belt loop that moves materials over long distances efficiently.
Common Applications:
- Mining (coal, ore, overburden)
- Cement plants (limestone, clinker)
- Packaging (boxes, cartons)
- Agriculture (grains, fertilizers)
- Airports (luggage handling)
Advantages: Versatile, cost-effective, works well for bulk and unit loads.
Limitations: Not ideal for very heavy or hot materials.
2. Chain Conveyor
Description: Uses interlinked chains to carry materials—suitable for rugged, heavy-duty transport.
Common Applications:
- Steel manufacturing (billets, coils)
- Automotive assembly lines
- Timber and lumber processing
Ideal For: High-load and hot material environments.
3. Roller Conveyor
Description: Uses rollers for transporting goods—powered or gravity-fed.
Common Applications:
- Warehouses (pallets, crates)
- Fulfillment centers (e-commerce)
- Assembly lines and sortation
Use Tip: Gravity rollers are great for reducing energy costs in short-distance layouts.
4. Screw Conveyor (Auger)
Description: A rotating screw moves materials through a tube or trough—excellent for bulk solids.
Used In:
- Food processing (grains, sugar)
- Waste treatment (sludge)
- Cement and fertilizer industries
Pro Insight: Great for metered flow but not suitable for fragile materials.
5. Bucket Elevator
Description: Lifts materials vertically using a series of buckets attached to a belt or chain.
Applications:
- Grain silos
- Cement kilns (raw meal)
- Fertilizer production lines
When to Use: Ideal when floor space is limited and height needs are significant.
6. Slat / Apron Conveyor
Description: Made of slats or plates for handling abrasive, hot, or heavy loads.
Used In:
- Automotive (engine blocks)
- Foundries and metal processing
- Ash or scrap handling
Durability Factor: Resists wear in extreme industrial conditions.
7. Spiral Conveyor
Description: A vertical, spiral-shaped conveyor that saves floor space.
Applications:
- Packaging plants
- Pharma and cosmetics
- Frozen food packaging
Why Use It: Efficient vertical transport in compact spaces.
8. Pneumatic Conveyor
Description: Uses air pressure or vacuum to move fine, dry materials.
Ideal For:
- Cement powder, fly ash
- Plastic granules, flour
- Pharmaceutical ingredients
Note: Requires dust control systems.
9. Overhead Conveyor
Description: Suspends loads from an overhead track—ideal for freeing up floor space.
Common Use Cases:
- Paint shops (cars and appliances)
- Garment factories
- Meat processing plants
Efficiency Tip: Reduces bottlenecks in floor-based workflows.
10. Modular Plastic Belt Conveyor
Description: Interlocked plastic segments designed for hygiene and easy cleaning.
Typical Applications:
- Food & beverage (dairy, baked goods)
- Meat and seafood processing
- Clean-room operations
Hygiene Advantage: Ideal for washdown environments.
Summary Table: Choosing the Right Conveyor
| Conveyor Type | Best For | Material Type | Orientation |
|---|---|---|---|

| Chain Conveyor | Heavy loads | Rugged, abrasive items | Horizontal/Incline |
| Roller Conveyor | Unit handling | Totes, boxes | Horizontal |
| Screw Conveyor | Controlled flow of powders | Dry powders, granules | Horizontal/Incline |
| Bucket Elevator | Vertical bulk transport | Grains, clinker | Vertical |
| Slat Conveyor | Hot or abrasive items | Scrap, molds | Horizontal/Incline |
| Spiral Conveyor | Tight vertical space | Packaged goods | Vertical spiral |
| Pneumatic Conveyor | Fine/light powders | Ash, flour, plastics | Horizontal/Vertical |
| Overhead Conveyor | Hanging objects | Apparel, carcasses | Overhead |
| Modular Plastic Conveyor | Washdown-safe environments | Meat, dairy, hygienic use | Horizontal/Incline |
How to Choose the Right Conveyor System?
When selecting a conveyor, consider:
- Material Type: Is it powder, bulk solid, unit load, or fragile?
- Environmental Conditions: Dusty, wet, hygienic, high-temperature?
- Throughput Needs: How fast and how much material must move?
- Space Constraints: Do you need vertical or space-saving options?
