Dear Iveeru,

design is depend on layout . can you send layout ?

Then we can deside what is a best way to transport lime stone.

Thanks

A small capacity of large lumps.

Old fashioned maybe, but I might have considered a skip hoist system. ■

Might have been my first choice, but 10" lumps means physically a large bucket to avoid the chance of jamming. Then a large bucket is disproportionate for 35 te/hr. ■

Russia had a system of a belt attached to buckets which handled ROM with larger lumps than noted in this thread.

The system was made a part of a USBM report on ROM transport about 20 years ago.

THey took a steel cord belt, attached large buckets to them, ran the buckets and belt on rails and there you have your system.

Dr. Olaf Klupfel wrote his doctoral thesis on the concept of using a steel cord belt bucket elevator concept. This work then became the property of Beumer: http://www.beumer.com/htcms/en/produ...elevators.html ■

I have followed this thread but did not offer my two cents until a friend suggested I do so.

Handling 6" to 10" material on a Dos Santos Sandwich Belt System is no problem it has been done at several well known installations. The belt width required will depend on the material mix and duty considerations, likely not less than (66") 1676 mm.

Due to the width requirement, then, the rate and profile are far too small for this to result in an economical solution.

The Russian belt car would be phenomenal overkill as it was developed to preclude the need to crush. Proposed material size was 1200 mm. To my knowledge it never established itself as a competitive solution in the open market.

Dear Joe,

I made a mistake and offered a solution for the other thread on steep downhill with large drop and lump size.

I did not offer the Snake due to the very high 800m drop distance and large lumps.

Have you anything close the the 800m drop?

I am pleased to note you are so well read on the many alternatives that do not always become common place. ■

Where did 800m drop come from??

It's 30 tph lifted 35 feet. ■

Larry,

Where is the other thread (down hill, 800m drop) that you are referring to.

The largest single elevation difference, to date, at a Dos Santos Sandwich Belt is 175 meters (elevating not dropping). This required modest 3-ply 750 PIW belts. Even if 800 meters single drop is not do-able why not multiple flights?

Joe Dos Santos ■

Dear Designer,

I appologized for the errant posting to this thread, in my first paragraph. I thought I was responding to another thread with the 800m drop.

Other thread: Steep Downhill Conveying ■

Dear Joe,

See other thread: Steep Downhill Conveying

You might find it to your liking. ■

Larry,

I can't seem to find that thread, can you be more specific.

Joe Dos Santos ■

Mi Amigo,

Look:

Forums > Mechanical Feeding and Conveying > Trough Belt Conveying > Steep Downhill Conveying ■

Larry,

Thanks. I have replied. Take a look when you get a chance.

Iveeru,

What would feed the conveyor & what would the conveyor feed? 30 tph x 10m is just about the limit for a bog standard builders chain hoist & kibble setup.

If I were you I'd forget about any conveyor for your job. There's too much of a missmatch. ■

A crusher is just what the guy doesn't need to lift 30 tph through 35ft. Did someone say missmatch? Where's that dust extraction salesman gone to? His ten bobs worth is well overdue.

It's got to be a hoist based on the information available so far. ■

Should the moderator of these forums start deleting posts that are clearly off topic??

Absolutely, and I am trying my best, but sometimes it is just not possible.

I welcome your help and watch function.

Dear Sir,

our company is since nearly 30 years in the range of Sidewall-

Conveyor Technology active and have equipped in the meantime more than 500 conveyors. We have great experience in conveying of limestone and want to ask you, to visit our website -

Please contact us for nearer informations respectively fill out our

questionnaire on our website.

Kind regards

Richard Lippert ■

Um, looks a bit lightweight for 10" lumps of limestone. ■

Iveeru,

I have asked you before to explain the input & output conditions of the required VERTICAL CONVEYING OF LIMESTONE lifting procedure.

Just imagine, for a moment, that you are an Engineer. Suppose someone asks you for a price for a bridge to take 35 tonne trucks over a river 60 m wide. Is the river in a gorge, meadowland or wash? We canot give meaningful advice if we do not know the story.

Your apathy to your thread has encouraged the confusion illustrated by (& on) the more recent sales pitched replies. ■

Dear Sir,

I fully agree with the replies of Designer. Also his observation on others reply is very much correct.- & every body should appreciate the same.

Regards.
