Different types of conveyor idlers for efficient material handling in industries

Conveyor idlers are an essential component of belt conveyors that support and guide the conveyor belt along the conveyor frame. They help in reducing the friction and wear between the belt and the conveyor frame, thus facilitating smooth and efficient material handling. There are several types of conveyor idlers available, each serving a specific purpose in the conveyor system. 1. Flat return idlers These idlers are used to support the return run of the conveyor belt and provide support to the belt as it returns from the head pulley to the tail pulley. They are typically installed at the tail end of the conveyor and help in maintaining proper tension in the return section of the belt. 2. Troughing idlers These idlers are installed on the carrying side of the conveyor belt and are shaped to create a trough for the belt to run on. They help in preventing material spillage and provide support to the belt as it carries the load. Troughing idlers are usually installed in sets of three to five idlers, depending on the width of the conveyor belt. 3. Impact idlers These idlers are designed to absorb the impact of the material being loaded onto the conveyor belt. They are typically installed at the loading point of the conveyor and help in reducing the impact of large and heavy materials on the belt. Impact idlers are usually made of rubber or polyurethane to provide cushioning and protection to the belt. 4 4 4 4types of conveyor idlers. Training idlers These idlers are used to adjust the alignment of the conveyor belt and prevent it from running off-track. They are typically installed on the return side of the conveyor belt and help in maintaining proper alignment and tension in the belt. Training idlers are adjustable and can be positioned to correct any misalignment of the belt. 5. Garland idlers These idlers are used in long-distance conveyor systems to support the belt along its length. They consist of a series of rollers mounted on a frame that runs the length of the conveyor. Garland idlers help in reducing the sagging of the belt and provide support to the belt over long distances. 6. Self-aligning idlers These idlers are designed to automatically adjust the alignment of the conveyor belt and keep it running straight. They are typically installed on the return side of the conveyor belt and use pivot arms to adjust the alignment as needed. Self-aligning idlers help in reducing maintenance costs and prolonging the life of the conveyor belt. In conclusion, conveyor idlers play a crucial role in the operation of belt conveyors by providing support, guiding the belt, and reducing wear and friction. With various types of idlers available, it is important to choose the right type of idler for your specific conveyor system to ensure smooth and efficient material handling.
