Types of Return Roller Conveyors

The versatility of return roller conveyors is evident in the variety of types available, each designed to meet specific operational needs and environmental conditions. Understanding the differences between these types can help in selecting the most appropriate conveyor return roller for a given application. Below is a detailed overview of the common types of return rollers for conveyors and their specialized counterparts.

Flat Return IdlersThese are the most basic form of return rollers, featuring a simple, flat design that supports the return side of the belt.Widely used in general material handling operations where the belt's return side does not carry any material.
Rubber Disc Return IdlersEquipped with rubber discs along the roller to help clean the belt by dislodging any material that may stick to the underside.Ideal for operations where sticky materials like wet sand or clay are handled, reducing maintenance and cleaning requirements.
V-Return IdlersComprise two or more rollers set in a V-shaped configuration to provide better belt support and alignment.Suitable for heavy-duty applications and environments where belt alignment is critical, such as mining and aggregate industries.

In addition to these common types, there are specialized return rollers designed to address specific challenges in conveyor operations:

  1. Impact Rollers: Positioned at loading points, impact rollers absorb the shock and impact of falling materials, protecting the belt and structure from damage.
  2. Guide Rollers: Installed on the sides of the conveyor frame, guide rollers prevent the belt from wandering off-track, ensuring smooth and aligned operation.
  3. Carrier Rollers: Also known as carrying idlers, these rollers support the belt and material on the carrying side, crucial for maintaining the belt’s shape and preventing sagging.

Each type of return roller conveyor offers unique benefits and is suited to particular applications. For instance, rubber disc return idlers are invaluable in environments where belt cleanliness is paramount, while V-return idlers are preferred in applications demanding enhanced belt alignment and stability. Similarly, impact rollers are essential in high-impact loading areas to extend the lifespan of the conveyor system.

Selecting the right type of return roller conveyor involves considering the nature of the materials being transported, the environmental conditions, and the specific operational requirements of the conveyor system. By matching the return roller type to the application’s needs, businesses can ensure efficient, reliable, and cost-effective conveyor operations.

FAQs about Return Roller Conveyor

What is return roller?

A return roller, part of a conveyor system, is a cylindrical component that supports the return section of the conveyor belt. After the belt has transported materials to their destination, it must return to the starting point to continue the cycle; return rollers facilitate this return path by allowing the belt to glide smoothly and with minimal resistance. These rollers are crucial for maintaining the belt’s integrity, preventing sagging, and ensuring efficient conveyor operations.

What are the different types of conveyor rollers?

Conveyor rollers come in several types, each designed for specific applications and operational requirements:
Carrying Rollers: Support the loaded section of the belt as it transports materials.
Impact Rollers: Positioned at the loading point to absorb the shock of heavy materials falling onto the belt.
Guide Rollers: Ensure the belt maintains its path and does not drift sideways.
Rubber Disc Return Rollers: Used on the return side, with discs that help to clean the belt.
Spiral Return Rollers: Have a spiral profile for self-cleaning to prevent material build-up.
Troughing Rollers: Form a trough shape to cradle the belt and materials being conveyed. Understanding the specific needs of your conveyor system is essential to select the appropriate type of roller.

What is the return idler?

A return idler is a type of conveyor roller that specifically refers to rollers mounted on the underside of the conveyor to support the return path of the conveyor belt. These idlers help to keep the belt clean, reduce wear, and ensure that it runs straight. They can be flat or may feature rubber discs or rings to aid in the cleaning process and to extend the belt’s life by reducing the accumulation of materials that can cause damage.

What is the spacing for return rollers?

The spacing of return rollers is a critical aspect of conveyor design and is determined based on several factors including belt width, the weight of the material being conveyed, and the belt speed. In general, return rollers are spaced further apart than carrying rollers because the return side of the belt is not loaded with material. Typical spacings can range from 8 to 10 feet for standard systems, but the specific spacing should always be determined by a thorough analysis of the conveyor’s operational requirements to ensure optimal performance and longevity of the conveyor belt and rollers.
