The core function of rollers
Jan 28,2026
Supporting conveyor belt and materials
The rollers support the conveyor belt evenly, avoiding excessive sagging due to gravity and tension, ensuring smooth operation of the conveyor belt. For example, in the mining conveying system, the rollers need to bear the huge weight of the ore to prevent the conveyor belt from breaking or deviating.
Reduce operational resistance
The flexible operation of the idler can reduce the friction between the conveyor belt and the idler, thereby reducing energy consumption. According to statistics, the resistance generated by the idler roller accounts for more than 70% of the total resistance of the conveyor, and its quality directly affects the conveying efficiency.
Control suspension and deviation
By properly arranging the rollers (such as self-aligning rollers), the suspension of the conveyor belt can be limited, material leakage can be prevented, and deviation can be automatically corrected to extend the service life of the conveyor belt.
