The crystallization process was not well controlled, resulting in the crystalline particles agglomerating into spheres.
It’s best to take a small ball and have it tested to see what impurities are inside
Hehe, your axial flow pump needs to be checked. It remains insoluble in salt; the salt acts as a crystal bed for the formation of balls along with other substances
There are impurities in the salt! The salting-out process needs to be carried out thoroughly to remove all the small balls!
It’s absolutely excellent; the quality is really high. What is an appropriate value for the A parameter in the cold tower soda production process?
I agree with what was said on the 4th floor; the core of the small balls should be salt particles. This kind of situation has occurred in our company before – the small balls obtained showed, upon analysis, an ammonium chloride layer on their surface with salt particles as their core. Taking other indicators into account and after further analysis, it is believed that the wear of the impeller in the axial flow pump may have led to an insufficient circulation rate in the crystallizer, causing the slurry layer to move downward and creating convective circulation within that layer, which in turn provided the conditions for granulation.
