Apparatus for production of sparingly water-soluble salt crystal grains |
摘要 |
An apparatus for producing sparingly water-soluble salt crystal grains, including a mixing vessel in which a cationic component solution and an anionic component solution are mixed to form a precipitation process solution in which sparingly water-soluble salt grains are produced, wherein the mixing vessel is connected to a reaction chamber through a one-way valve, and the precipitation process solution is injected into the crystal growth process solution through the one-way valve immediately after mixing while stirring the crystal growth process solution.
