In ancient China, the high rotary drum car and the tipping car for lifting water were the rudiments of the modern bucket elevator and scraper conveyor. In the middle of the 17th century, the empty cableway was used to transport bulk materials. In the middle of the 19th century, the screw conveyor appeared one after another in various modern structure conveying equipment. In 1905, the steel belt conveyor appeared in Switzerland. In 1906, the screw conveyor appeared in England and Germany Inertia conveyor. Since then, the conveyor has been continuously improved under the influence of the technological progress of mechanical manufacturing, electrical machinery, chemical industry and metallurgical industry, and gradually developed from the completion of the transportation within the workshop to the completion of the material handling within the enterprise, between enterprises and even between cities, which has become an indispensable part of the mechanization and automation of the material handling system

The main mechanical conveying equipment includes:

1. Pipe chain conveyor

2. Belt conveyor

3. Roller conveyor

4. Bucket elevator

5. Screw conveyor

6. Plate chain bucket elevator

The characteristics of the conveying equipment is a kind of friction driven machinery to transport materials in a continuous way. Using it, the material can be transported in a certain conveying line from the initial feeding point to the final discharging point to form a material conveying process. It can not only transport the broken materials, but also transport the finished products. In addition to pure material transportation, it can also cooperate with the requirements of the technological process in the production process of various industrial enterprises to form a rhythmic flow line. So conveying equipment is widely used in modern industrial enterprises.
