What are the factors that affect the particle size distribution of heavy soda ash?
Thread Content
The heavy and low-salt soda ash is the development direction. The particle size distribution of heavy soda ash is an important indicator. So what are the factors that affect the particle size distribution of heavy soda ash? How to deal with it? I hope all sea friends will discuss this issue.
The turbidity of the finished product, the temperature of the light ash entering the crystallizer or hydration machine, the temperature of the hydration machine or crystallizer. A heavy ash furnace or fluidized bed is used.
This unit uses a heavy ash furnace. Do the calcium and magnesium ion content of the refined brine and the quality of the carbonized crystals also have an impact?

I am the victim of frequent quality accidents in heavy ash because the calcium and magnesium ions in the refined brine are too high! ! ! ! Problems occurred every three days, but I couldn't find out the cause. Finally, I found out that the calcium and magnesium ions were too high.

I think the bicarbonate content in light ash also affects heavy ash, but there is also no data.

Crystallization temperature, alkali concentration, fluidized bed selection
The heavy ash furnace has a bit of a crushing effect on alkali monohydrate, mainly because the fluidized bed has a winnowing effect and the particle size can be adjusted. The fluidized bed can produce heavy ash with a particle size of more than 90. The calciner cannot reach it unless a sieve is added.
Thank you, I have a certain understanding. It seems that the fluidized bed has more advantages. Is it not as easy to operate as the calciner?
The fluidized bed consumes high power, is equipped with three large fans, and its operation flexibility is not as good as that of a calciner.
