| Abstract: | According to the industrial crystallization and phase diagram theory,the main factors which affect crystal granularity in the potassium chloride production process by cold decompositoon-hot dessolve crystallization were studied in the experiment.The effect of the every main factor on granularity was analysed and the concrete approach to increase product granularity in the production was pointed out .It proved that the product with granalavity up to 0.49mm and 99% of KCI (dry basis) can be abtained by proper control condition. |
