Types of Industrial Conveyors
There are two main conveyor technologies: bulk material and unit handling. There are also many different conveyor types. Belt conveyors are the most popular type of product. These versatile, reliable industrial conveyors are made of an endless, fabric-covered belt that traverses between two or more pulleys and is supported by idler rolls at intermediate points. Belt conveyors can move materials ranging from fine powders to large, lumpy stones at belt speeds ranging from 20 to 300 m/min. Industrial conveyors differ in terms of features. Roller, live roller, belt and gravity conveyors are designed to allow the accumulation of materials. Industrial conveyors with magnets are used to move ferrous materials. Types of industrial conveyors include:
- Air tables and ball transfer tables - Air transfer and ball transfer tables are used with products that must be manually rotated or correctly positioned. They can also be used when more than two conveyor lines converge and packages must be transferred from one line to another.
- Anti-static conveyors - Anti-static conveyors are made of materials that do not allow the build up or storage of an electrical field.
- Auger conveyors
- Belt conveyors - Belt conveyors include flat belt, magnetic belt and trough belt conveyors.
- Bucket conveyors - Bucket conveyors are industrial conveyors that consist of a bucket elevator and an endless belt or chain with a series of attached buckets.
- Cart-on-track conveyors - Cart-on-track conveyors are used to pull a cart along a track. Basic components include a rotating tube, track, and cart.
- Chain conveyors - There are five types of chain conveyors: push-bar conveyors, twin chains conveyors, sliding chain conveyors, heavy-duty plates for assembly conveyors, and apron or slat conveyors.
- Chute conveyors - Chute conveyors are used to link two powered conveyors together, and for accumulation in shipping areas.
- Cleated conveyors - Cleated conveyors are designed to transport and control material over an inclined or horizontal plane.
- Drag conveyors
- Flex turns
- Flexible screw or auger conveyors
- Free and power conveyors
- Gravity conveyors
- Pneumatic tube conveyors
- Pneumatic or vacuum conveyors
- Roller conveyors
- Sanitary conveyors - Sanitary conveyors can be sterilized and are designed for medical, pharmaceutical, and food processing applications.
- Screw conveyors
- Slat conveyors
- Sorting conveyors - Sorting conveyors are used for merging, identifying, inducting, and separating products to be conveyed to specific destinations.
- Table top conveyors
- Tow line conveyors
- Trolley conveyors
- Vertical reciprocating conveyors - Use a single platform, forks or cage to lift or lower loads between various levels in intermittent flow operations.
- Vertical continuous conveyors - Use multiple platforms, forks or cages to lift or lower loads between various levels in intermittent flow operations.
- Vibrating conveyors - Consist of a trough supported by tuned springs and/or hinged links having a drive system. The drive system is arranged to oscillate the trough, causing solid particles to be moved along the trough.
- Washdown-capable conveyors - Washdown-capable industrial conveyors are also associated with sanitary or hygienic applications.
Performance specifications for industrial conveyors include:
- Maximum load
- Load capacity
- Volume of material transported
- Mass flow of material
- Number of pieces per minute.

Related Products & Services
Air conveyors are devices that use airflow to move items or media. Products include air tables, pneumatic tube conveyors, and vacuum conveyors.
Bulk Handling Conveyors
Bulk handling conveyors carry materials such as grain, coal, pellets or any other powder, granular or bulk media.
Unit Handling Conveyors
Unit handling conveyors are designed to handle packages, pallets, or any other unit format. They are used to transport large, discrete items that can be handled independently.
Vertical conveyors are used to lift or lower loads between various levels in intermittent flow operations and where horizontal space is limited. There are two types of vertical conveyors, reciprocating and continuous.
