A belt conveyor in a conveyor, which is a relatively common conveyor that can be transported horizontally or at a certain angle of inclination. There are two types, fixed type and mobile type. Among them, the mobile type can adjust the working position and the conveying height, while the fixed type is fixed and dead, and cannot be moved. Screw conveyor, which is also one of them, is mainly used for conveying and lifting machine to load and unload bulk solid materials. Its main advantages are simple structure and low cost. However, if you want to transport abrasive, or toxic, or corrosive materials, then you need to use a vibrating conveyor, screw conveyor is not suitable. However, the use of vibrating conveyors also has some drawbacks and limitations, mainly because it cannot be used to transport materials that are easily broken or sticky, which is prone to problems. Moreover, it is not possible to carry out the inclined conveyance at a large angle. Therefore, in summary, different types of conveyors have a certain range of materials to be transported, so we have to select them in order to be able to select the most suitable ones and get good transport results.
