A conveyor belt (or Belt conveyor ) consists of two or more pulleys, with a continuous loop of material – 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. Belt conveyor is widely used in industries like metallurgy, coal, hydroelectric and chemicals as a kind of conveying equipments in a continuous way driven by friction. It has such advantages as large conveying capacity, simple structure, convenient maintenance, low operation cost and strong generality. With the rapid development of our economy, belt conveyor has wider application in international market.
In this way, it has become an important auxiliary equipment in stone production line by combining with stone crushers such as jaw crusher or hammer crusher. Roller is the key part of belt conveyor for supporting the conveyor belt and the stone materials. Roller can not only decrease the operation obstruction of the conveyor belt, but also guarantee the deflection of belt not exceed the technical regulation so as to make the belt operate in the specified direction smoothly and steadily. So roller is one of the most important parts which can influence the using effects. And this decides that manufacturers have to pay enough attention to the design and choice of rollers.
In order to adapt to the development of modern industry, our belt conveyor reduces the rotating speed of roller by increasing the diameter of rollers. On the other hand, the design of rollers is also very important because reasonable design will not increase the investment cost. Hongxing has spent long time on the design and production of high capacity and low cost belt conveyor, so it is areliable manufacturer and supplier of belt conveyor
