4. Training Idlers: Training idlers guide the belt and ensure it runs true along the conveyor path. They can be manually adjusted to correct belt alignment and are often used in conjunction with self-aligning idlers. Properly adjusted training idlers help prevent belt misalignment, reducing wear and operational disruptions.
5. Transition Idlers: Transition idlers are placed where the belt changes from a flat profile to a trough profile or vice versa. These idlers help to gradually transition the belt, reducing stress and preventing material spillage. Properly selected transition idlers ensure smooth transitions and maintain the belt’s stability and efficiency.

The selection criteria for types of idlers in carrying idler belt conveyor systems involve careful consideration of load capacity, environmental conditions, belt speed, troughing angle, and maintenance requirements. The impact of different types of idlers on conveyor performance underscores the importance of choosing the right idlers for specific applications. By understanding these factors and their implications, operators can ensure efficient, reliable, and long-lasting conveyor operations.
