Crystallization is opposite of dissolution. It is the production of a suspension of solids from a solution (often called a “mother liquor”) of the solid component in a liquid. Mechanisms include evaporation, cooling and chemical reaction. Crystallization is often a subcategory of solids suspension. Uniform suspension is often required. Minimizing particle attrition is often an important consideration. There are a variety of specialized vessel and mixer configurations used in crystallization operations on an application specific basis.

Vessel Design Considerations

See Solids Suspension. However, there are many specialized “crystallizers” that use unique vessel designs for individual applications. These must be configured on a case by case basis.
