Re: Long Distance High Capacity Belt Conveyor
A 9 km, 6400 t/h (coal) single flight can provide you with a good solution that is within bankable industrial norms.
The temperature range does not have excessive lows.
I do not know what you are requesting with the optimum length. Are you asking how long can you go in a single flight? If so, there are other factors to be considered before an appropriate answer can be offered.
The noted single flight may not be at minimum cost. Longer certainly will not be a minimum cost.
Further questions should be put in the hands of an expert that you are willing to pay for. ■
Re: Long Distance High Capacity Belt Conveyor
Dear Sir,
considering some rough values, the 9 km conveying length for your application is definetely no problem. Belt Width is approx. 2m, speed 5.5 or 6 m/s, required power to be installed approx. 7MW. Result (as Mr. Nordell already indicated): all required components are in industrial morms.
Regards, ■
Re: Long Distance High Capacity Belt Conveyor
Dear Mr.Nordell / Mr. Axel Witt
Thankyou very much for taking interest in our prolem. We want to install 6000 TPH conveyor for straight length of 9 km. The tentative drive requirement is about 7MW as mentioned by Mr. Axel.
What is the general recommended size/ rating of single drive unit. How many drives are required to meet this requirement and it's positon. Is this possible to have a single length of 9km or need to break the entire length in two or three lengths.
Can you advise us about the palces where such capacity conveyor were installed with more than 5km single length. ■
Re: Long Distance High Capacity Belt Conveyor
JKB,
First, Axel and I agree that there is no restriction on the technical design which will easily meet your request.
Second, Axel and I disagree on the magnitude of drive requirements and belt width. So, we have a differing view of the project economics.
Third, the forum is for concept points, ideas, problem solving in the generic sense, not engineering. Your last request about having somebody commit to doing free engineering shows a lack of respect of other peoples time. Both Axel and I have given our time beyond a short response to give you clues.
Fourth, I offer a short list of projects > 5km and/or 6000 tph under CDI design (mechanical (M) and/or control(C)) or design audit (A):

9. 16 km ZISCO, 1995 (?) 500 tph - MC in partnership with E.L. Bateman
10. 6 Km Collahuasi, 2001(?) 10,000 tph x 8000 kW, partner Krupp
11. 10 km x 2 flights Channar Australia 1989, now at 4600 tph - M lead design consultant to Hamersley Iron
12. 5 km, German Creek Australia, 2200 tph, M, partner BMCL
13. 6;5 km, Muja/Collie, 800 tph (?), M, partner BMCL
14. 5 km, Yandi, BHP Australia, 4,000 tph - M - partner Voest-Alpine
15. 7 km, Port Hedland Biway, 5000 tph (4000 & 1000 tph) - A to BHP direct
16l 13 km, Kaltim Prima Coal, now at maybe 4000 tph or more running over 8 m/s - A to client
17. A bunch in Brazil with Voest Alpine, some at 16,000 tph all MC
18. Some in China
19. 20.3 km (now dry commissioning -( tracks as designed with multiple horiz. curves), Curragh, Australia, 2500 tph - MC - partnership Laing O'Rouke
20. Doing one in India over 5 km partner MECON
21. Doing one in USA @ 8.5 km, 2100 tph, partner FLS - MC
22. A bunch in feasibility that are already in construction, some over 15 km.
I probably forgot a fair number. These are off the top of my head without references, hence (?) details. ■
Re: Long Distance High Capacity Belt Conveyor
ALL of the above CDI references are single flights. I now remember more but will leave it stand. ■
Long distance high capacity belt conveyor
We are in the port industry, for our new expansion we want to install about 6000 to 6400 TPH belt conveying system for coal. The distance to be conveyod is about 9kms in straight length.
We would like to know can we have a single conveyor of above mentioned capacity ? or what is the optimum length of the conveyor to handle the coal at 6000 to 6400 TPH capacity? ■
