Wear the tape, increase running resistance, increase power consumption, and even cause the tape to slip and cause fire accidents.
The function of the roller is to support the weight of the conveyor belt and materials. The operation of the roller must be flexible and reliable. Reducing the friction between the conveyor belt and the rollers plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the roller is a small component in the belt conveyor and the structure is not complicated, it is not easy to manufacture high-quality rollers.
The criteria for judging the quality of rollers include the following: roller radial runout; roller flexibility; and axial movement.
