Idlers are cylindrical rods that extend under and along the conveyor belt. It is the most important component/assembly of the trough belt conveyor. The idler is usually located in the trough-shaped metal support frame under the support side to support the conveyor belt and materials.

There are two types of idler rollers: carrying idlers and return idlers. They are located on the support side and return side of the conveyor. These idlers have many types and functions due to specific applications.

Troughers are common carrying idler types on the load side of conveyors. They are usually installed in a trough-shaped frame on the load side along the length of the conveyor belt to guide the rubber conveyor belt and support the conveyed material. The trough idler includes a central idler with a certain width and side wing idlers on both sides of the central roller.

In quarry and mining applications, when large, heavy and sharp materials fall onto the conveyor belt, they can cause impact and damage to the conveyor belt, which ultimately leads to downtime and higher replacement costs. Therefore, an impact idler is required in the material impact area.

Picking table idler is usually used at the material loading point under the hopper. Compared with trough idler, the center roller of picking table idler is longer, and the short roller with 20 trough angle can disperse materials to the greatest extent and make inspection and classification easier.

The misalignment of the conveyor belt may cause material overflow. Therefore, when installing the idler rollers, a self-training idler group must be installed, which can control the alignment of the conveyor belt on the support side. A self-training roller is usually placed at intervals of 100-150 feet. When the total length of the belt is less than 100 feet, at least one training idler should be installed.

The flat return idler is the most common idler on the return side of the conveyor to support the return run of the conveyor belt. It consists of a steel rod installed on two lifting brackets, which can effectively prevent the belt from stretching, slack and damage.

It is used to control the alignment of the conveyor belt on the return side to prevent damage to the conveyor belt and structure. The installation distance is the same as the self-training idler on the support side.

The return idler group composed of two rollers is called V return idler group. Usually used for long-distance land conveyors, suitable for applications requiring heavy, high-tension fabrics and steel cord conveyor belts. Two rollers have a higher rated load than a single roller, which can provide better belt support and belt training.
