The conveyor idler is composed of transmission roller, tensioning roller, support plate, idler, motor and bearing belt. There are a lot of idlers in a conveyor. The quality of idlers has a great impact on the running resistance of belt conveyor, the service life of conveyor belt, energy consumption, maintenance and operation cost.

The conveyor idler adopts black rubber belt, which can be applied to the heavy-duty transportation of bagged objects or sand, stone and coal. In addition, baffle, skirt and other accessories can be added or removed on the belt to meet the transportation of bulk materials, and guide strips can be installed at the bottom to realize positive and negative transportation. Operation platforms can also be installed on both sides of the belt conveyor, and accessories such as lighting lamps and fans can be installed on the top to make an assembly line in the electronics and hardware industries. Through electrical control, the degree of automation can be improved, the labor input can be reduced, the investment cost of the enterprise can be reduced, and the production efficiency of the enterprise can be improved.

Idler is an important part of conveyor, with many kinds and large quantity. The quality of idler directly affects the quality of conveyor. The idler of the belt conveyor determines the use effect of the conveyor, especially one of the most important parts that determine the service life of the conveyor belt. The structure of the idler group largely determines the size and nature of the load borne by the conveyor belt and idler.

The basic requirements of belt conveyor for idler are: reasonable structure, durability, good dust-proof and waterproof performance of sealing device, and reliable use. The bearing shall ensure good lubrication, light self weight, small slewing resistance coefficient, low manufacturing cost, smooth idler surface, etc. The function of the supporting idler is to support the conveyor belt and the materials on the belt, reduce the sag of the belt, ensure the smooth operation of the belt, and form a trough section in the loaded branch, which can increase the transportation volume and prevent the leakage of materials on both sides.
