The influence of the parameters such as mechanics, crystallization area, is a very complicated influence system.In order to obtain, particle size distribution characteristics are good, purity
High crystalline product, in crystallization process, need to control crystallization temperature, input concentration and mold liquid level height, to ensure
The stable operation in Metastable zone of degree of supersaturation in crystallization process, to prevent substantial amounts of two grades and primary nucleation, it is accordingly required in particular to control
Cooling curve in crystallization process processed.The natural cooling process not controlled, occurs degree of supersaturation peak value, no in the early stage of process
Occurs spontaneous nucleation with can avoiding, the deterioration for causing product grain size number to be distributed.
