Re: Iron Ore Closed Storage In Port
The question is how big is your expense account?
An elevated conveyor tripper in the roof line of any storage would work.
How far is it from the discharge point to the stock yard? I am asking as "a single capsule pipeline for the entire system" can do both jobs with less work and labor as well.
The reclaim is the puzzle, the least work would be to install a stationary belt conveyor fed by a track mounted WR stamler belt feeder as an example that could be fed by a dozer or small front end loader. A WR Stamler belt feeder can easily match your reclaim requirments with no problem.
Having a linear stock pile allows you to follow the stock pile with the belt feeder using its crawler drive and simply dump onto the conveyor feeding the stationary capsule pipeline loadout at the mid point as well.
The loading system could be the halfway point in the stock pile and it can be fed by a short conveyor loaded by the WR Stamler belt feeder.
A small silo feeding a modified ore skip pant leg bin loading system using five pantleg bins to load five capsule train cars at a time will work very well.
A capsule pipeline would work well for this installation to deliver the concentrate and pellets to the stock pile as the same system (one installation) can be used as for everything as it is even less work than a belt conveyor and your desired tonnages are well within its capabilities.
Another option is to use a capsule pipeline to deliver the ore and pellets directly to the port. the weight of the concentrate and pellets will allow you to have huge efficiencies in any case or all cases.
The single pipe system developed by Brink Weaver at Pneutrans in Toronto is the least costly to install and a loop system allows one to load and unload with with out stopping around the clock unaffected by weather and a system only requires one employee per million tons moved from a to b.
To see an existing capsule pipeline in operation since 1983 please google (karasawa mine) this system has been in place.
since 1983 and been operatingf around the clock with 87%+ effiency.

Covered Storage For Iron Ore In Port
iron ore fines containing 9% moisture and pellets do not require covered storage. These is no possibility of dust nuiscence / fugitive dust during operations in the port.
You want to handle three products which have different physical characteristics (angle of repose, bulk density etc.). Pellets will need a seperate stockpile.
for 6 mpty daily movement will be about 20,000 Tonnes or 7 rail rakes in India. iron ore fines with 9% moisture do not flow out with ease from BOXN rail cars. So you may have to consider wagon tippler installation. From then on it is a layout with lontitudenal stockpiles with boom stackers and reclaimers. ■

If you check up with Google Earth there is often a "paint the town red " scene near iron ore export terminals. As rightly said, it is influenced by the ambient moisture levels. Your customer quality assessor is the guide. If he is prepared to buy and ship water content then let him. Otherwise you must consider the break even of a vast storage shed in uncertain economic times. Covered storage is a big decision and the environmental aspects will force many marginal exploits out of contention. ■

Gary,
If you decide to go with a covered pile, please consider calling us for a bid. We'd be happy to work with you.

Iron ore closed storage in port
Hi,
Can someone tell me the possible options for closed storage of ore in port :
a. Annual exports of 6 MMTPA : Concentrate – 4 MMTPA / Pellets – 2 MMTPA
c. Ore density : Concentrate – 2.4 T/m3 / Pellets – 2.6 T/m3
d. Moisture Content : Concentrate – 9% / Pellets – 2%
e. Particle Size : Concentrate 40% below 0.15mm & 60% between 0.15 to 6mm / Pellets – 10 to 30mm
Should a longitudinal storage or closed storage be planned ? and what are the approx costs for circluar stacker reclaimers (3000tph/1500tph) as compared to longitudinal stackers reclaimers ?
There are no restrictions on height or available ground area in the port.
Tks, Gary ■
