Belt Conveyor Idler commonly used in Conveyor System

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.

Trough Idlers&#;

Trough idlers are the most common type of carry idler, which are typically designed with 3 or 5 idler rollers and are fitted to the carry-side of the conveyor belt. The 5-roll idler offers more uniform cross section, resulting in a greater net carrying capacity. The 3-roll design has a centre idler roll and wing idlers on either side.

The benefit of using a trough idler is that they help to ensure the load-bearing capacity of the conveyor belt is the same along the length of the belt. With a more even distribution of load-bearing, the maximum capacity of material at the loading point won&#;t fall off of the belt.
