The roller is an important part of the belt conveyor, with many types and large quantities, which can support the weight of the conveyor belt and materials. It accounts for 35% of the total cost of a belt conveyor and produces more than 70% of the resistance, so the quality of the roller is particularly important. It has two kinds of steel and plastic.
The role of the roller is to support the conveyor belt and the weight of the material. Roller operation must be flexible and reliable. Reducing the friction between the conveyor belt and the roller 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 part in the belt conveyor and the structure is not complicated, it is not easy to make a high-quality roller.
The criteria for judging the quality of the idler are as follows: the radial runout of the idler; the flexibility of the idler; the axial channeling.
