Common type belt conveyor consists of six main components: gear , tail and turn back into the unit , the middle frame, tensioning devices and tape. Currently, the belt conveyor is moving long distance , high speed, low friction direction, in recent years the cushion belt conveyor is one of them . In the belt conveyor design, manufacture and application , we now compared with foreign advanced level there is still a wide gap between domestic production belt conveyor in the process of designing and there are many deficiencies.

Continuous conveyor belt conveyor is a continuous conveyor is fixed or migration -lift transport aircraft in one of the main types , which is characterized by the formation of transport to the loading point mount point between continuous material flow by continuous material flow whole movement to complete the logistics from the loading point to the unloading point of delivery. In industry, agriculture , transportation and other enterprises, the production process is continuous conveyor composed of rhythmic flow transport line indispensable component. Continuous conveyors can be divided into : a flexible conveyor traction objects , such as belt conveyors, slat conveyors , scraper conveyors , bucket conveyors, escalators and aerial tramway , etc. ; object does not have a flexible traction transport machines, such as screw conveyors , vibrating conveyors , etc. ; pipe conveyer ( fluid conveyance ) , such as pneumatic conveying equipment and hydraulic pipes.

Which is a continuous conveyor belt conveyor is the most widely used , belt conveyors , reliable operation, transmission capacity , transmission distance is long , easy to maintain , to adapt to the metallurgical coal , machinery and electric power, light industry, building materials, food and other departments .

Long-distance, large-capacity , high-speed belt conveyor is the latest development. And other transport equipment ( such as locomotive class ) compared not only with long-distance belt conveyor ( single length up to 5000 m , and can be connected in series to achieve multi-machine lap , transport distance up to 206km), large capacity , continuous transport features, and reliable operation, easy to automate and centralize control , economic benefits are obvious. Belt conveyor operation and maintenance costs far less than highway Automotive ways, and as long as the production of more than 5 years , belt conveyors way than a total investment of highway Automotive much less so in the production process, who can achieve belt conveyors occasions , generally using a continuous conveyor belt conveyor . Compared with other equipment , belt conveyor has the following advantages :长距离，大容量，高速皮带输送机的最新发展。和其他运输设备（如机车类）相比，不仅具有长距离胶带输送机（单根长度可达5000米，可串联连接，实现多机搭接，运输距离高达206公里的），大容量，连续运输的特点，运行可靠，易于实现自动化和集中控制，经济效益是显而易见的。皮带输送机的操作和维护成本远远低于公路汽车的方式，只要汽车公路总投资超过5年以上，皮带输送机的方式生产少得多，所以在生产过程中，谁能够实现皮带输送机的场合，一般采用的是连续输送机皮带输送机。皮带输送机与其他设备相比，具有以下优点：

( 1 ) conveying a wide range of materials ;
( 2 ) a wide range of transmission capacity ;
( 3 ) transmission line adaptable ;
( 4 ) flexible loading and unloading , the flexibility achieved by one or more points or discharge ;
( 5 ) the reliability and safety ;
( 6 ) low cost.
