Idler is one of the main components of belt conveyor. Its role is to support the conveyor belt, reduce the running resistance, and make the sag of the conveyor belt not exceed a certain limit to ensure the smooth operation of the conveyor belt.
The total weight of idlers accounts for about 30%-40% of the total weight of the belt conveyor. Because of the large quantity, the quality of idlers directly affects the normal operation and operating costs of material handing.
From the point of view of belt conveyor system engineering design, it is mainly to select and arrange idlers.
