Types of Conveyor Belts

Conveyor belts play a pivotal role in streamlining operations, enhancing efficiency, and optimizing the flow of goods. These versatile systems come in various types, each designed to meet specific industrial needs and operational challenges. Understanding the "types of conveyor belts" available is crucial for businesses looking to improve their logistics, increase productivity, and ensure smooth operations within their facilities. In this article, we explore the different conveyor belt types and their applications in warehouse automation.

Introducing conveyor belt systems

Conveyor belts are automated tracks used to transport materials and goods within a facility. They are an essential component of modern warehousing, offering a reliable and efficient method for moving items across various distances and configurations. By automating the movement of goods, conveyor belts reduce manual labor, minimize handling times, and improve overall operational flow.

7 types of conveyor belts and their applications

Several types of conveyor belts cater to the diverse needs of warehouses and distribution centers. Each type has unique features and benefits tailored to specific goods, environments, and operational requirements. Let’s go through the 7 main types of conveyor belts and their functionalities.  

1. Roller conveyor belts

Description: Roller conveyors consist of rollers mounted on a series of supports, creating a path for items to roll along. They can be powered (driven by motors) or gravity-based (where items move down a slope).

Applications: Ideal for moving boxes, pallets, and other items with a firm bottom. Roller conveyors are commonly used in shipping and receiving areas, as well as in assembly lines.

2. Belt conveyor belts

Description: These conveyors feature a continuous belt made from various materials (like rubber, PVC, or fabric) that moves over a series of pulleys. They are powered by motors and can transport items of various sizes and shapes.

Applications: Belt conveyors are versatile and used for moving products along a flat or inclined path. They are suitable for packaging lines, sorting operations, and the transport of delicate items.

3. Modular plastic conveyor belts

Description: Made from plastic modules interlocked in a bricklayed pattern, these belts offer high durability and flexibility. They can easily be cleaned and configured to suit various layouts.

Applications: These are used in food processing, pharmaceuticals, and any application requiring high levels of hygiene or where the conveyor path may need frequent changes.

4. Flexible conveyor belts

Description: Flexible conveyors are extendable, with sections that can be curved, stretched, and contracted. They are typically made of steel rollers or skate wheels mounted on a flexible frame.

Applications: Best for loading and unloading trucks, moving goods around obstacles, and temporary setups in shipping areas.

5. Slat conveyor belts

Description: Slat conveyors consist of slats or plates attached to a chain. They provide a solid, flat surface for products to rest on as they move along the conveyor.

Applications: Useful for heavy or hot items, such as metal parts, that might damage other types of conveyors. Also used in assembly lines and for moving items through ovens or cooling areas.

6. Spiral conveyor belts

Description: Spiral conveyors save space by transporting items vertically. They consist of a continuous belt that forms a spiral path, allowing items to ascend or descend within a compact footprint.

Applications: Ideal for multi-level warehousing operations, where space is at a premium. They are used to connect different floors or levels efficiently.

7. Pallet conveyor belts

Description: Specifically designed to transport pallets, these conveyors can handle heavy loads and are available in roller or chain versions.

Applications: Pallet conveyors are essential in warehouses dealing with bulk goods and heavy items, facilitating the movement of pallets to and from storage areas and loading docks.

Matching the right type of conveyor belt to industry needs

The choice of a conveyor belt system is pivotal in optimizing operations across different industries. Each industry presents unique challenges and requirements, from the delicate handling of pharmaceuticals to the rugged demands of heavy manufacturing.

Manufacturing and assembly lines

Roller conveyor belts are highly efficient for moving components and assembled products due to their ability to handle heavy loads and facilitate easy transportation along the production line.

Packaging and distribution

Belt conveyor belts offer versatility and gentle handling, making them ideal for moving packaged goods of various sizes and shapes through sorting and packaging processes.

Food processing and pharmaceuticals

Modular plastic conveyor belts are the go-to choice for these industries, thanks to their easy-to-clean surfaces and adaptability to various layouts, crucial for maintaining high hygiene standards.

E-commerce and retail distribution centers: Flexible conveyor belts cater to the dynamic environment of e-commerce warehouses, allowing for efficient loading, unloading, and adaptable routing of goods.

Heavy industry and metalworking

Slat conveyor belts are best suited for transporting heavy or hot materials, such as metal parts through ovens or cooling areas, due to their durable and heat-resistant design.

Multi-level warehousing and logistics

Spiral conveyor belts provide an effective solution for space-saving vertical transport, connecting different floors or levels without the need for large footprints.

Bulk material handling

Pallet conveyor belts are designed to move heavy loads, such as pallets or large containers, making them essential for industries dealing with bulk goods transportation and storage.

By identifying the unique requirements of each industry—from hygiene standards in food processing to heavy-load handling in manufacturing—the selection of a conveyor belt system can be optimized to enhance operational efficiency, safety, and productivity.

Materials used for different types of conveyor belts

Conveyor belts are crafted from various materials, each offering distinct advantages and challenges to suit different industrial needs. Rubber belts are renowned for their durability and ability to transport heavy loads, making them ideal for mining or construction, but they struggle in extreme temperatures. PVC belts, on the other hand, offer a versatile and chemical-resistant option, suitable for a broad range of industries, though they may not handle very heavy loads as effectively as rubber.  

Fabric belts are lightweight and flexible, perfect for food processing or packaging applications, but they lack the robustness for heavy-duty tasks. Steel belts excel in high-temperature environments and are unmatched in durability, yet their weight and cost may limit their application. Modular plastic belts provide excellent flexibility and easy maintenance, particularly in food processing, but might come with higher initial costs and lower load capacities compared to metal options. Wire mesh belts are suitable for drying processes, offering good airflow and durability, but their open design may not be appropriate for very small items.  

Each material brings a unique set of properties to the table, influencing the conveyor belt's performance, maintenance needs, and application suitability, making it crucial to select the right material based on the specific requirements of the operation.
