In the paper, the advantages of pipe belt conveyor are introduced. Calculation of pipe belt conveyor s main parameters is different from that of conventional belt conveyor s. The parameters such as throughput, belt speed, belt width, resistance, tension in belt and power are described. The length of transition section is analyzed because it is important to the belt life. Hexagon supporting rollers and tipping device are necessary parts ofpipe belt conveyor. The structures of them are also discussed. keywords: Pipe Belt Conveyor, Transition Section,Hexagon Supporting Rollers, Tipping Device 1. Introduction Pipe belt conveyor is a new type of special belt conveyor which developed from the conventional belt conveyor. In this conveyor, flat belt is forced to be tubular by supporting roller groups and material conveyed is enveloped in it. Therefore airproof convey is realized in whole conveyance line. Pipe belt conveyor was proposed in 1964 by Japan Pipe Conveyor (JPC), and it went into real use in 1979[1] .After that, it was rapidly developed in Gennany and America and widely used abroad. But it is not deeply studied and its use is much limited in China. 2. The characteristics of pipe belt conveyor Figurel is for the structure of pipe belt conveyor. The load is putted on by the feeder at the end of conveyor. The belt is flat when it runs through the driven roller and it is conducted by a series of supporting rollers to be tubular gradually. Thus airproof conveyance is realized. In order to discharge, the pipe is also conducted by a
