Gravel vs ballast

[SeeYou190]

I know nothing of blast furnaces.

Would the limestone fed into it need to be precisely sized, washed, and dried? Or, would any mixed batch of limestone left-overs be acceptable?

I need something to represent limestone that is ready to be fed into a blast furnace.

On another board I saw where someone used WS buff ballast.   

You can also buy small bags of pulverized or crushed limestone.

On another board I saw where someone used WS buff ballast.  WS also has buff gravel. What's the difference between these products?

I looked at the images, and I see no difference. It looks like fine gravel and coarse ballast are the same. Hopefully someone that has both products can fill us in with true details.

Limestone gravel varies in size more than ballast. Limestone gravel is sorted from sizes less than 1/2" to more than 2". It matters for what it will be used for.

Down here, limestone is nearly pure white.

Thanks.  WS has grey in ballast and gravel also.  Are they just the same product labeled differently?
