Types of rollers

The general classification of rollers in China's roller industry is based on different methods such as materials and functions. According to the materials, there are steel rollers, ceramic rollers, rubber rollers, polymer rollers, etc., according to the function classification, there are adjustments. Core rollers, friction rollers, parallel rollers, spiral rollers, etc.
  The roller is an important part of the belt conveyor. There are many types and large quantities, including various trough rollers, buffer rollers, parallel rollers, etc. At present, it includes iron rollers, ceramic rollers, rubber rollers, etc. It is one of the most used parts of belt conveyors and the most convenient maintenance. It accounts for 35% of the total cost of a belt conveyor and generates more than 70% resistance, so the quality of the roller is particularly important. The role of the roller is to support the weight of the conveyor belt and the material. The operation of 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 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.
