Crystal is a common phenomenon in alkali recycling process of pulp and paper manufacture industry. The principle and process of recycling and the serious crystal phenomenon are introduced. The diameter distribution of the particles and the difference between the component of green liquor and crystal in pipeline which is linked from green liquor pot to assimilation apparatus are examined and analyzed. The preliminary conclusion on the flow pattern is that the flow of green liquor is solid-liquid two phase flow of suspending entity, the mechanism of crystal is produced by the sedimentation, flocculation, and adsorption of particles. Therefore, the degree of crystal is closely related to the diameter distribution of particles in the flow.Moreover, for the metal elements in the pipeline coagulation which are not in green li-quor, the process is not only physical but also chemical, therefore, it should be studied comprehensively.
