Belt Conveyor is a friction drive conveyor transported materials continuously. Belt conveyor machine comprises the rack, conveyor belt, pulley, rollers, tensioning devices, driving unit and other components. It not only conveys material, but also can cooperate with various industrial equipments to form a rhythmic transport line.

Type Introduction and Maintenance of Conveyor Belt Rollers
A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types ofconveyor systems. A belt conveyor system consists of two or more pulleys(sometimes referred to as drums), with an endless loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley. There are two main industrial classes of belt conveyors; Those in general material handlingsuch as those moving boxes along inside a factory and bulk material handlingsuch as those used to transport large volumes of resources and agricultural materials, such as grain, salt, coal, ore, sand, overburden and more.
Belt conveyor roller is an important part of belt conveyor. It accounts for a total cost of 35% of a belt conveyor, suffered more than 70% of the resistance. So the quality of roller is particularly important.
The role of roller is to support the belt conveyor and the weight of material. Roller must be flexible and reliable operation. Although the roller in the belt conveyor is a small part, structure is not complicated, it is not easy to produce high-quality roller. The conveyor rollers of our company are well accepted by the customers for their higher quality, reasonable price and good service.
The Carrying roller is usually equipped in the belt conveyor, which is widely used in coal mines, metallurgy, ports, construction site, power station, and chemical, food industries.
Today there are many types of rollers as follows:
The standard tough angle of trough roller is 35 degrees, so most of conveyors use 35 degrees trough rollers and 35 degrees trough bend forward rollers.
Impact roller angle includes 35 and 45 degrees, when using the canvas conveyor belt, only the 35 degrees tough impact roller can be selected. groove rollers. 45 degrees trough impact roller can be used in the section where the guide chute will not be affected by material impact .
Transition roller is used for belt conveyor with large capacity, long distance and large conveyor belt tension.
Return roller is also called below parallel roller, it is also the most used one kind of the roller.
Self-aligning roller includes ordinary self-aligning roller, friction self-aligning roller and tapered self-aligning roller. cone-shape self-aligning roller. Self-aligning roller is applied to automatically correct excessive running deviation appeared in the process of operation to guarantee the normal work of belt conveyor.
Since rollers occupies large quantity of belt conveyor parts, so for belt conveyorrollers, maintenance is particularly important. During the process of using, please keep the belt conveyor roller working in a dry environment, change the damaged roller in time and keep the roller surface clean.
