Coveyor Ilder Description
The idler set is the most important component of the trough belt conveyor, which is a cylindrical rod extending below and along the conveyor belt. The rollers are usually located in a grooved metal support frame under the support side and are used to support the conveyor belt and the material. Depending on the purpose of use, the roller set is installed in different positions on the belt conveyor. Depending on the position in the conveyor, there are two types. Above the conveyor belt is the Carrier Idler and below the conveyor is the Return Idler.

They are usually located on top of the belt conveyor and are used to carry the material from A to B. Therefore, Carrier Idlers are often used to better catch and transport the material. They are usually divided into trough idler, upper training idler, impact idler, and garland idler.
Trough Idler
Groove idlers are the most common type of idler and are usually designed with 3 or 5 rollers mounted on the conveyor side of the belt. The advantage is that they help ensure that the carrying capacity of the conveyor belt is the same as the length of the belt. The load-bearing distribution is more uniform to ensure the maximum load-bearing capacity of the loading point and ensure that the material will not overflow from the belt.
Impact Idler
Impact idlers are usually wrapped in rubber and used in the loading area of the conveyor belt. Increase the contact surface between the material and the belt, reduce the impact force, and prevent damage to the conveyor belt, idler frame, and surrounding structure.
Upper Training Idler
The Upper Training Idler aligns the belt perfectly and returns it to the correct position during the belt conveyor operation. Incorrect belt stitching or unbalanced material bearing will cause belt offset. Aligning idlers can align the belt with the idlers to prevent belt breakage.
Garland Idler
Each roller of the garland idler set can be moved in a certain position according to the movement of the conveyor material. If your delivery system needs to be more mobile, or when the environment is not suitable for static idlers, you will need garland idlers. These idlers are attached to the conveyor frame for better mobility.
Usually located underneath the belt conveyor, they are used to carry the belt back to the starting point and bring it back to A. Usually flat or V return idlers are used to adjust the position of the belt so that the belt returns to the starting point smoothly. They are usually divided into flat return idlers, V return idlers, and training return conveyor idlers.
Flat Return Idler
The flat return idler set consists of a single piece of steel mounted on two drop supports. They also consist of two rollers. The purpose of using flat return idlers is to support the belt from the return side to prevent belt stretching, sagging, and failure, thus increasing the service life of the conveyor belt.
Training Return Idler
The training return idler set detects the belt misalignment and corrects it to ensure that the belt is accurately tracked at the end of the conveyor during operation. The use of down-centering return idlers helps to reduce belt damage and maintenance costs associated with belts, structures, and components, ensuring the smooth and normal operation of belts and conveyors.
V Return Idler
V Return Idlers consisting of two rollers are typically used on long overland conveyors for applications requiring heavy-duty, high tension fabric and steel cord core conveyor belts. The two rollers have a higher load rating than a single roller, providing better belt support and belt adjustment and return. the angle of the V Return Idler is usually 10° or 15°.
In addition to the above idlers, belt conveyors will also utilize some special idlers, please refer to the article What is roller conveyor system? for more details.
