Experiments were conducted on the adding of Ferric Ammonium Citrate (FAC) solution, as an anti-caking agent, to High Grade salt. In those experiments, water solution of FAC of normal temperature was added to the salt in the head of the second basket of a continuous push type centrifugal separator by using a rectangular nozzle. When the quantity of the salt was limited to 2.33-3.63 t/h and the adding rate of the FAC solution was fixed 14 1/h, the following results were obtained: (1) The yield of FAC was 80%. (2) The variation of FAC contents in samples from a produced lot was 19.5% as coefficient of variation. The quantity of a sample of the salt was 50grams. (3) When the FAC content in the product was designed to reach 10 ppm, the content range of 2δ in the product was 6.1-13.9 ppm. In this case, the concentration of the FAC solution in the product was about 570 ppm. (4) The increase of moisture of the product, to which FAC was added, was about 0.3% as compared with the product without FAC.
