What are the Different Types of Belts Used in Conveyor Belt Systems

Conveyor belt systems are among the most widely used forms of material handling equipment in various industrial sectors. These systems utilize continuous belts to transport materials or products from one point to another. The efficiency and effectiveness of a belt conveyor system greatly depend on the type of belt used, as each type has distinct qualities tailored to specific conditions and applications. In this article, we explore the plethora of belt types designed for conveyor systems and their unique purposes.

1. Flat Belts

Flat belts are the simplest form of conveyor belts, consisting of a flat surface. These are typically made from materials like rubber, leather, fabric, or synthetic substances. These belts are versatile and are commonly used in transportation for products with a solid base. They can move items at high speeds over long distances and are perfect for carrying things on a straight level or through inclines and declines.

2. Modular Plastic Belts

This variety uses a series of interlocking plastic pieces to form a robust and flexible belt. Modular belts are ideal for handling irregular-shaped products. Due to their design and material, they are particularly resistant to abrasion and corrosion, making them suitable for the food processing industry, where ease of cleaning is paramount.

3. Cleated Conveyor Belts

Incorporating raised cleats into the belt’s design allows these conveyors to transport materials on an incline or decline efficiently by preventing slippage or rollback. The cleats ensure controlled product spacing, accurate sorting, and secure carriage of goods. They are extensively used in recycling, material handling, and food packaging industries.

4. Wire Mesh Belts

Constructed with intertwined metal wires, wire mesh belts are widely employed in high-temperature environments. Their open design allows for adequate airflow, which is essential for applications in baking, drying, and cooling. Metal wires provide durability and resilience against heat and potential damage, qualifications necessary for furnaces and foundry operations.

5. Plastic Belting and Chain

These belts, made of plastic segments connected in a chain-like fashion, provide high strength and multi-directional functionality. The plastic belting and chain are effective in scenarios requiring tight turns and complex routes. Their versatility makes them a popular choice in food and beverage conveying, including bottling plants.

6. Woven Metal Belting

As one of the more durable varieties, woven metal belts can withstand extreme operating environments. This type is customarily chosen for its ability to manage heavy loads, resist high temperatures, and survive abrasive conditions. Industries like forging, welding, and casting find these belts indispensable.

7. Filter Belts

These belts come with varying levels of permeability to facilitate the drainage or filtration of carried products. Filter belts are particularly crucial in wastewater treatment facilities, allowing water to pass through while capturing waste particles. The industry also employs these belts in various de-watering technologies for food products and mining processes.

8. Hinged Belts or Plate Link Belts

Constructed from plates or castings linked together, these rugged belts are used to handle heavy and rough materials. Their robust nature makes them favorable for the metalworking, industrial scrap management, and die-casting applications. They are known for their durability and longevity, even in demanding conditions.

9. Timing Belts

These belts have teeth on the inner surface that mesh with gear-like pulleys. Timing belts are designed for synchronization and precision, making them ideal for applications that require accurate placements, such as in automated assembly lines where precise component positioning is necessary.

10. Ribbed Belts

These belts boast longitudinal grooves along the conveying surface. The design of ribbed belts provides enhanced grip and stability for the transported items, making them favourable for transfers where slipping is a concern or where high-powered motors are used.

The selection of a conveyor belt type takes into account factors such as the nature of the material to be conveyed, the environment of operation, the durability needed, and the specific processing requirements. Industries need to choose the appropriate belt type to maximize productivity, safety, and cost-efficiency within their operations. Whether it’s moving delicate bakery items across a facility, sorting packages with care, or transferring metal scraps in an industrial setting, there exists a conveyor belt precisely engineered for every conceivable application.
