Heavy soda ash production discussion.

What factors do you think affect the quality of heavy soda ash production, including drum water mixing machine, drum water mixing machine, and liquid phase hydration method. I'll go first and start the conversation. 1. The temperature of the light ash must be at least higher than 160 degrees. 2. The total alkali content must be at least 99%. 3. The reaction temperature should be above 90 degrees. 4. The turbidity of the light ash should be below 100. 5. Is there any requirement for the temperature of the combined water? We control it at about 50 degrees. 6. The composition of combined water. Because we are using wet dust removal, we use soft water containing about 20tt of alkali as the combined water liquid phase hydration method.: The concentration of the mother liquor is above 120tt, the temperature of the mother liquor is 80-90 degrees, and the temperature of the crystallizer is 90-105 degrees. I hope everyone can make some suggestions. Furthermore, I personally feel that the drum type water mixing machine is more stable than the drum type production.
The particle size of the heavy ash in the solid phase hydration method is worse than that in the liquid phase. How to solve the problem of large particles in the solid phase heavy ash?
Grading and screening, large particles are then crushed. We use a fluidized bed to produce heavy ash, and fine powder can remove light ash.
If the whiteness of light gray is no problem, what are the generally influencing factors on the whiteness of heavy gray? How to control and adjust operations?
The simplest method is to screen and return the large particles back to the system.
The quality of combined water, product particle size, impurities and other factors may affect the whiteness of heavy gray.
If there is no problem with light gray iron, the whiteness is no problem.
That's not necessarily the case. If there is a problem with the combined water, it may also lead to a decrease in whiteness.
The concentration of the mother liquor must be at least 300g/L! If the concentration is too low, more alkali must be added and less mother liquor must be added.
The concentration of the mother liquor should be at least 300g/L to 360g/L! If the concentration is too low, more alkali must be added and less mother liquor must be added. Is the so-called combined water you are talking about desalinated water? Or something? I haven't heard of it in the heavy gray position. Can you explain it to me?
As far as I know, desalinated water is mostly used for combined water.
