Flashy Business!
Keep the bin as full as possible to minimise the bin ullage which in turn will reduce the available air to carry the dust to the baghouse. Sprays are out of the frame since you might cause a flashing hazard downstream in the process.
There was a recent ship loading spout mentioned on the forums recently. It looked impressive and might fit your bill. It lurks about a dozen threads back. ■

Re: Pellet Dust
So you mean that pellet will have dust during unloading to truck?
I thought that pellet particles are bigger than 9mm and it doesn't have dust, isn't it? ■

Dust Control Of Pellet Dust
Dear Mohandes,
We can assist you to control your pellet dust with a system which requires no utilities and has no internal moving parts - therefore product degradation is reduced.
The DSH System excludes air from the material being transferred. At the point of loading, or transferral, the DSH System concentrates the discharge of dry goods as a tight solid column through free air into any target repository including, trucks, rail cars, ships, barges, stockpiles, storage containers and/or bags. Loading can be continuous without plant interruption. The DSH System reduces hazards, health and environmental concerns and product wastage.

Dsh For Pellet
Dear JudiDSH,
Have you ever installed DSH for iron ore pellet?
How this system can be installed under a bin which feed truck?
I guess it makes the required height more, isn't it?
Whatabout abrasion problem? does it include liner?
As you know iron ore pellet is abrasive. ■
Iron Ore Pellet Loading
Hello Mohandes,
Yes it is very dusty. We recently did a project for Arcelor. The project had truck dumping, truck loading and railcar loading.
I think we accounted for 2000 to 2500 cfm dust collection at each of the DCL loading nozzles. All other transfer points need to be addressed. Dust should be the least of your worries. Iron ore pellets can also self heat under certain conditions so you need to be able to inert the system and have some type of emergency dump if the temp gets too high. Mass flow becomes important or at least addressing valley angles to ensure a first in first out process. There are other important factors you need to consider in your design related to direct reduced iron pellets including the abrasiveness.
Good luck with your project

Re: Pellet Dust
Thanks for your attention. However would you please give us more information about your experience:
Is that iron ore pellet was the production of DRI or production of pelletizing plant before feeding DRI? ■
Experience With Pellets
My experience with iron ore is with "direct reduced iron" in the form of pellets. In one location we loaded them into trucks and trains. At another location we unloaded them stored them in a silo.
I think the onus is on you to supply more information on your needs, including type of material, silo size loading and unloading conditions etc. My project is complete it does not need anymore attention.
I look forward to hearing back from you

Iron Ore Pellet From Concentrate
Dear Liam,
Our iron ore pellets is the production of pelletizing plant from iron ore concentrate. These pellets will feed to another steel plant such as DRI which is not include in our project.
So I think our material will not have problems of self-heating, are you agree? ■
Iron Ore Pellet Handling - Safety
I think that question is best saved for your supplier of pellets. At the same time you should probably ask them if the dust is explosive. I believe the answer is probably yes to both questions. I can not confirm the properties of a material in such a forum. My suggestion is that you get your responses in writing by someone who is responsible for the operation. ■
Pellet Dust
we would like to install a bin for loading iron ore pellet to trucks.
As you know pellet particle size is in the range of 9-16mm and it doesn't include fine materials.
So would you please inform me if you have any experience with pellet loading:
loading from belt conveyor to the bin, does it have dust?
loading from bin to the truck, does it have dust?
what is best dust control, dust suppression with spray water or dust collection? ■
