The mother liquor is returned to the suction of the propeller circulator after the fines have been destroyed by heating or mixing with dilute feed or water, depending on the flowsheet. Around 1920, having a semicylindric horizontal hollow trough in which a hollow screw. The Swenson-Walker crystallizer is a model, specifically conceived by Swenson Co.

Fines leaving the baffle zone are sent to a following stage, settler, or heat exchanger in the case of an evaporative DTB crystallizer. These fines are separated from the growing suspension of crystals by gravitational settling in the annular baffle zone. Surrounding the suspended magma is an annular settling zone from which a stream of mother liquor bearing fine crystals can be removed.
The DTB crystallizer is built in both the adiabatic cooling and evaporative types and consists of a body in which growing crystals are circulated from the lower portion to the boiling surface by means of a large, slow-moving propeller circulator. This type of crystallizer is used primarily in the production of a variety of large-size crystalline materials such as ammonium sulfate, potassium chloride and diammonium phosphate for the fertilizer industry. For superior control over particle size when excessive fine crystals are present, the Swenson draft tube baffle (DTB) crystallizer has been proven highly effective. Swenson Walker Crystallizer Pdf Rating: 3,8/5 731votesĭraft tube crystallizers are for superior control over crystal size and characteristics.
