ABSTRACT:
A crystallization vessel is provided which includes an elutriation column having an outlet at an upper end thereof and an inlet at a lower end thereof which inlet is in communication with a body of slurry contained therein. Flow regulating means associated with the elutriation column outlet enables the flow velocity within the column to be regulated for controlling the size of crystal particles removed from the slurry body through the elutriation column outlet. A movable baffle in the column is also provided for selectively varying the cross-sectional area of the column and thereby independently regulating the quantity of slurry removed from the slurry body through the elutriation column outlet. In this manner, both the size and quantity of crystal particles removed from the slurry body are independently regulated, thereby providing product crystals of improved size uniformity.
