Abstract

 Bucket Wheel Stacker and feeder is a highly efficient for handling equipment, is widely used in thermal power plants, port, iron and steel metallurgy, mining, cement building materials, chemicals, coal and coke plant, and other raw materials storage and transportation field, can be realized coal, ore , Chemical raw materials and other bulk material from the reactor, transit, handling of the continuum.
 Belt conveying systems is expected bucket Stacker and an important link in the machine, in other areas also widely used. Modern belt conveyor is an important material for transport equipment, is no reason for the movement of mechanical conveyor belt transporting goods, with the belt conveyor belt as a conveyor belt known as the conveyor belt, or tape machines. It is simple in structure, low cost, long distance transport, high efficiency advantages. Its mainly used for metallurgical, mining, coal, power plants, ports and industrial enterprises. It is China's handling of the mining mechanization and modernization of increasing the contribution.
 This paper presents a bucket Stacker and feeder in the transport belt machine. First of all, the work on the belt conveyor characteristics, Development, principle, classification and secondly, the friction on the tape drive principle; Finally, the working conditions under their belt conveyors, including the transmission of the slowdown Is part of a detailed design and design calculations, the simple analysis of the belt material deviation and spread the causes and solutions, has introduced several other forms of belt machine.
Key words: belt conveyors: Belt conveying systems ;Development survey; reduction gear
