1. What is a roller?

The roller, which is an important part of the belt conveyor, can support the conveyor belt and the weight of the material. It accounts for 35% of the total cost of a belt conveyor, which produces more than 70% resistance, so the quality of the roller is particularly important. It has two kinds of welding methods,one is traditional and the other is friction-welding,and the friction-welding track roller is better.

2. Differences between Friction-welding and Traditional Type

• Friction-welding track roller is better in the wear-resistance and has a longer working lifetime.
• Consumption of raw material: the roller bodies of  traditional track roller are connected by the welding rod. but the friction ones are connected by the friction between rollers bodies. So the friction-welding roller will be added more raw material to make sure the roller is perfect to the standard size after welding. 
• Inner parts: For the traditional rollers, the welding is done after two processes of maching,so the size of the inner parts are not so precise as friction-welding ones. For the fricion-welding ones, after the weilding, there is one more precise maching with concentric locating to make sure the conformity of inner size,this means the inner parts are more precise with higher standard.
