I'm student at Technical University in Kosice, Slovakia. I'm working on my diploma work.

I need to teoretiocaly solve the problem of Coal handling from stockpile to ship. Known parameters are:

conveyor width=1000 mm

bulk density=2700 kg/cu m

lmp size=30 mm

surcharge angle = 20 degrees

I also need to develop power of motion.

Thank you

It is not very clear what are your requirements / assignment. Possibly, you want to design conveyors. For designing the conveyors, first one has to fix the layout or profile drawing of the conveyor. One cannot design conveyor, unless this information is available.

You have mentioned bulk density of coal as 2700 kg/cu m, which is erroneous. Normally coal bulk density will be in the range of 750 to 1000 kg / cu m. Also, conveying rate mtph is necessary. There are well known methods for designing the conveyor, you can find such literature applicable to this subject. In case you are interested, I have authored & published a book on Belt Conveyor which effectively deals with almost all issues of the conveyor including your subject. Please contact me if you need additional information on the book.

Thank You For Your Intersting

There was a mistake because material to be conveyed is Iron Ore, not Coal like I have writen.

Capacity is 300 t/h

Thank you for your reply.

Dear Sir,

Mr. Mulani noted that you have not provided sufficient details to allow this forums specialist to provide help.

Following are the minimums in addition to your specs.:

1. Length

2. Vertical and Horizontal Arrangements

3. Operating temperature - max & min

4. Moisture Content

5. Tonnage

Noting you picked the width, what about the speed? Why not state the problem constraints and see what others will say about your problem.

Does your professor know you are getting professional help?

Get Your Self A Demo Software

Juraj,

The best place to start is with a demo software that does what you want. This way you can find what you need and maybe it will help you define the things that you need better....

On our site at www.overlandconveyor.com you will find Belt Wizard II for designing conveyor belts you can download it and use it on your problem and it should give you what you need...

Juraj,

We also encourage you to use The CDI conveyor design program BELTSTAT. It too can be downloaded free of charge to demonstrate the many variables that can be studied.

Conveying Problem

Posted on 12. May. 2005 - 08:09

Hello Juraj,

Is it a conveying problem or your problem?OK, you have not given any data to calculate.

Cap. Q= 3600xVxArea x bulk density x.8

Considering 300x1.2=360t/hr. as design capacity, velocity will come out 0.41m/sec (say0.5m/sec) . So 1000mm belt width is too big. Here area is 0.111 sq. M against 35 deg. trough angle& 20deg. surge.I will give more to you. I assume the following:

Length=200M

Lift=5M

Vel.=1.0m/sec

Then the following will come out.

Belt KW=22

Belt rating= 500/3

T1=38766N

T2=17649N

You give me proper details, I will give you all hand out calculation for you.But have you noted the last line of Mr.Nordell's reply?

Cheers.

Dear Mr Juraj Antonak

Before using any software of conveyor design you should have atleast basic knowledge of conveyors

If you want to understand basic design philosophy of belt conveyors, I suggest to go thru hand book like CEMA belt conveyors for bulk materials or ISO 5048.

Dear Mr Banerjee

It hardly matters CEMA is hand book or not but it is BIBLE for bigners

Singh Shab,

I agree with your views.But for Mr.Juraj the books which I refered by me are more useful.He is a student.

Dear Mr.Juraj,

Some of the useful books are for you.

1.Materials Handling. by.. Ya. I. Oberman

2.Land reclaimation Machinery. by...T. Borshchov& R. Mansurov

3.Open cast Mining. by... V.V. Rzhevsky

After studing the above books, then you purchase Belt conveyor design book by our FORUM member Mr. I.G.Mulani.

Martin Engineering has a book you should agquire that will you undrestand belt comneyors. It is called FoundationsIII. Check our website on how to obtain a copy. WWW.martin-eng.com. Good luck in your assignment.
