Powdery materials such as lime, dedusting ash, desulfurization ash and fly ash shall be transported in a closed manner by means of tubular belt conveyor, pneumatic conveying equipment and tanker. Iron concentrate, coal, coke, sinter, pellet, limestone, dolomite, ferroalloy, blast furnace slag, steel slag, desulfurization gypsum and other lumpy or sticky wet materials shall be transported in a closed manner by tubular belt conveyor or belt corridor; if it is really necessary to transport by automobile, it shall be transported in a closed carriage or covered tightly, and dust suppression measures such as humidification shall be taken during loading and unloading. Material conveying and blanking points shall be equipped with gas collecting hood and dust removal facilities, or dust suppression measures such as spray shall be taken. Wheel and body washing facilities shall be provided at the stock yard exit. The roads in the plant area shall be hardened, and cleaning, watering and other measures shall be taken to keep them clean.

2) The cross-sectional dimensions of the truss of the pipe belt conveyor are shown in the following figure. The truss structure includes the truss body, walkways and railings. Considering that the pipe belt conveyor does not have return spreading materials, only the walkways on both sides are included, and the truss closed part only includes the rainproof color plate and fixing frame above the truss of the pipe belt conveyor.

7. Weight comparison summary:
1) The body part of the two does not include the adhesive tape and truss structure. The total weight of the belt conveyor is 293 256 491=1040kg, the total weight of the pipe conveyor is 495 360=855kg, and the belt conveyor is about 20% heavier than the pipe conveyor;
2) The main body contains adhesive tape, belt conveyor 1 040 450=1490kg, pipe belt conveyor 855 710=1565kg, and the pipe belt conveyor is about 5% heavier than the belt conveyor;
3) The biggest difference between the two weights lies in the truss part, and the weight of the closed corridor of the belt conveyor is basically 1.7 times the weight of the truss of the pipe belt conveyor;
4) The weight of the two trusses is much larger than the weight of the equipment body. After all the weights are summarized, the total weight of the belt conveyor is about 1.6 times of the total weight of the pipe belt conveyor.
5) If the closure is not considered, the weight of the belt conveyor truss and the pipe belt conveyor truss is basically the same.

The cost of belt conveyor is 3520 2560 4910 7680=16370 yuan, the cost of pipe belt conveyor is 5940 3600 17040=26580 yuan, and the cost of pipe belt conveyor is 1.6 times that of belt conveyor.
2) According to the fully enclosed summary of environmental protection requirements, the cost of belt conveyor is 155570 yuan, the cost of pipe belt conveyor is 107980 yuan, and the cost of belt conveyor is 1.44 times that of pipe belt conveyor.
　　
4. Conclusion
1. Compared with the overhead full-pass closed corridor belt conveyor and the overhead pipe belt conveyor, the weight of the belt conveyor is about 1.6 times of the weight of the pipe belt conveyor, the cost of the belt conveyor is about 1.44 times of the cost of the pipe belt conveyor, and the investment cost performance of the pipe belt conveyor is better than that of the closed corridor belt conveyor.
2, closed corridor belt conveyor if you need to reduce costs, you can start from the corridor structure, the specific summary of the next issue to share the "tube belt conveyor and fully closed corridor belt conveyor cost comparative analysis (II)."
