Black foreign matter in soda ash
Thread Content
There have been several cases where soda ash contains black foreign matter. The black foreign matter is insoluble in water and not soluble in acid. I don’t know what it is and it gives me a headache!
Not a belt scumbag? Or metal?
Confirmed that it is not belt residue, but also a non-iron compound, which I can’t figure out.
No. Because it is an accidental phenomenon and not common, no pictures are left.
It probably isn't, and it's confirmed that it isn't.
Don't worry about accidental events.
It should be belt slag, which has also happened in our company. Check the wear of the conveyor belt.
