Selection of coal bin discharger
Thread Content
What type of discharge devices are used for the coal bins in the water-coal slurry gasification system, prior to the coal entering the mill? A star-shaped feeder? Is there anything better?
Is it just a different name? It’s called a belt-weighted coal feeder, a feeder, or a discharge device. . . In any case, it’s about how to ensure smooth discharge from the coal bin.
Is there also a feeder? By directly opening a bar valve or a gate valve at the bottom of the coal bin, the coal will fall due to gravity. How to ensure smooth operation? The coal bin lining should not fall off, and smooth operation is achieved when the moisture content of the coal is below 14%.
This is actually a problem that needs to be addressed from end to start. The main issue related to material discharge is its adjustability; the stability of material discharge in a conical silo under the effect of gravity basically relies on luck – if that \"luck\" runs out, problems arise. Therefore, it’s necessary to address the root cause: what is it that affects the stability of material discharge?
Knowing that there is a gate plate below the coal bin, I guess what I want to ask is which type of belt feeder is more stable.
