| Abstract: | This paper introduced the quality character of NaCl crystal produced with CaSO 4 type brine. It adjusts the flow of circulating feed liquid in differential effects through the reformation of operating processes and the third effect merged into the Oslo crystallizer for improving the granularity of NaCl crystal and accreting the function of salt washing. |
