Roller: It is an important part of the belt conveyor, with many types and large quantities. It accounts for 35% of the total cost of a belt conveyor and withstands more than 70% of the resistance, so the quality of the rollers is particularly important.
The role of the rollers is to support the conveyor belt and material weight. The roller must be flexible and reliable. Reducing the friction between the conveyor belt and the idler 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 idler is a small part in the belt conveyor and the structure is not complicated, it is not easy to manufacture a high quality roller.
The criteria for judging the quality of the roller are as follows: the radial runout of the idler; the flexibility of the idler; the axial turbulence.
Use and operation of the roller:
1. Before using the roller, carefully check the appearance for serious bump damage. The rotating roller should be flexible and free from jamming.
2. The installation distance of the roller should be determined scientifically according to the type of logistics and the characteristics of the conveyor. Avoid excessive or excessive installation.
3. The roller installation should be adapted to avoid mutual friction.
