    Description

    The forced circulation crystallizer, also known as the growth type crystallizer, has a conical bottom in the crystallization chamber. After discharged from the conical bottom, the crystal slurry is pumped to the heat exchanger through the circulation tube with an axial flow circulation pump, and then enters the crystallization chamber again after being heated or cooled. This cycle is endless and belongs to the crystal slurry circulation type, which can be operated continuously or intermittently.
    Vapor recompression (thermal TVR or mechanical MVR) can also be used. Forced circulation crystallizers can operate from low vacuum to atmospheric pressure. Usually, this kind of devices are used in situations where high evaporation rates and crystal size are not the most critical or where the requirements to the crystal growth rates are moderate. It is suitable for the production of sodium chloride, barium chloride, potassium chloride, urea, sodium hypophosphite, sodium sulfate, ammonium sulfate, citric acid and other inorganic and organic crystals, with product particle sizes ranging from 0.01 to 1mm.
