Abstract
Japanese salt production companies have been developing their own technologies for various salt products as independent private companies. In particular, customers require various particle-size choices.
A conventional conical classifying crystallizer was installed and various particle sizes of salt, in the range between 350 and 3,000μm, have been manufactured in our factory. Even though obtainingwider size selections mainly depends on differences in crystallizer construction, satisfactory results on the commercial production of desired particle sizes in good yields were obtained by usingan operation line diagram, after confirming factors of crystal growing rate and seed generationrate at start-up stage, in which seeds were grown up to 2,300 μm as desired, in batch and continuous commercial plant operations.
