Idler roller is an important part of belt conveyor, with many kinds and large quantity. It accounts for 35% of the total cost of a belt conveyor.
Idler rollers bear more than 70% of the resistance, so the quality of the roller is particularly important.
The function of the idler roller is to support the conveyor belt and the weight of the material. Roller must be flexible and reliable operation. Reduce the friction of the conveyor belt with the roller, which plays a key role in the life of conveyor belt, which occupies more than 25% of the total conveyor cost. Although the roller in belt conveyor is a small part, the structure is not complicated, but it is not easy to manufacture high quality roller.
The standard for judging the quality of roller is the following: the radial pulsation of the roller, the flexibility of the roller, the axial movement of the roller.
