Selection of centrifuge screens

The production process involves three-effect, four-unit operation, with salt being taken from a high-level tank containing brine; the temperature in the second effect is around 120 degrees. Since the screen of the original centrifuge was selected based on parameters for 30% alkaline solution, it now needs to be replaced with one suitable for 42% alkaline solution. However, due to my lack of experience, I am not familiar with the parameters required for selection{:3_56:}. I hope that the experts here can provide some assistance{:3_53:} (Centrifuge model: P-60). Additional question: 1. Is there a table showing the particle size of salts when they crystallize at different temperatures? 2. What are the factors that affect the size of salt crystal particles? # hcbbs
