Re: Unit Train Wagon Loading
Gentleman, How many rackes you will like to load in a day/what capacity you want to achieve in a year.You can achieve up to 6000 tph in the case of iron ore and 4000 tph in the case of coal.In India, existing flood loading systems are designed keeping in view of one full racke capacity/storage in the silo but the in latest system there is no need to have one racke capacity in the silo. With two silos having capacities of 700 t and 70 tonnes you can achieve the capacities provided your reclaim capacity is compatiable with flood loading capacity.
I can help you out to design the system.

Unit Train Wagon Loading
Aneet,
In Australia (and if I may offer my apologies on behalf of all decent Australians for the 2nd test debacle) we regularly load iron ore fines and lump products (-6mm and +12 -32mm material) through a train load out system designed by Schenk Australia. Rates are in excess of 9,600t/h with train lengths of 230 cars (BHPBIO = 2 rakes, RTIO have one consist of 210 - 236 cars).
The surge bin at the end of the reclaim line is 2,000t, based on a bulk density (fines) of 2.2t/m3. The bin uses a clam shell loadout chute and train speeds are up to 1km/h. Mining Area C (BHPBIO) is now pushing for a very fast train speed of 1.5km/h on their latest expansion (from 25 to 50Mt/a).
Sinter fines are quite nasty to deal with, but the Schenk load out I commissioned at Mining Area C in 2003 was processing Marra Mamba ore with ultra-fines (-12micron) of up to 30% by weight. This stuff is basically clay and when wet (>9.5% moisture) has been known to develop "rhino horns" on impact plates of 1m or more in length on less than 1 minute.
Happy to provide any further information you require. ■
Re: Unit Train Wagon Loading
To answer your question, more information is needed. What is the method of storage and reclaim? What is your required loading rate? How is the feed to the loading system controlled? Is it desireable to load each wagon with precision?
We can custom design a loading system to meet your needs. Using a loading system because it works someplace else is generally not advised since most facilities have different needs.
If you would like to get in touch with us, we can discuss your application to determine your requirements. ■
Re: Unit Train Wagon Loading
Dear Shri Aneet G,
The surge capacity of the hopper fundamentally depends upon the inflow rate and duration versus outflow rate and its duration. If you are going to feed the hoppers simultaneously during unloading of the hopper then surge capacity is to be decided considering following aspects.
- Inflow rate and duration (for example you may be feeding for 12 hours nut unloading is to continue for 16 hours, by any of the reason).
- Possible sudden non-operational status of the inflow system, say for one hours or two hours, and for making it again operative. This is like a contingency for the situation.
If there is no inflow then naturally the storage capacity will be equal to the entire quantity to be loaded. However this will be very uneconomical and in general simultaneous feeding and unloading is considered which may be different with respect to capacity and duration.
It is possible that the reclaim system which is feeding might have higher capacity and then it may remain idle for some time etc. It is also possible that feeding rate could be less wherein the surge capacity to compensate till the full quantity has been loaded.

Unit train wagon loading
Gentlemen,
I am presently involved in a project which demands flood loading of sinter fines and BF grade iron ore lumps thru the same loading station. Is there any reference for such a loading station? In case it is a workable solution thenwhat should be the ideal surge capacity in the loading station. Please remember operating conditins are worst particularly during monsoon.
regards
