AN APPARATUS FOR CRYSTALLIZATION COMPRISES A CRYSTALLIZATION VESSEL (52), A SEED SUPPLYING DEVICE, A FEED SOLUTION SUPPLYING DEVICE AND A TUBE BAFFLE DISPOSED WITHIN THE CRYSTALLIZATION VESSEL (52). THE TUBE BAFFLE IS PROVIDED WITH A CRYSTALLIZATION PORTION IN AN INNER AREA AND A LOWER AREA THEREOF, AND THE TUBE BAFFLE (54) AND THE CRYSTALLIZATION VESSEL DEFINE A CLASSIFICATION PORTION (A) THERE BETWEEN. THE APPARATUS FURTHER COMPRISES AN AGITATING FAN (58) FOR AGITATING THE SEED CRYSTALS AND THE FEED SOLUTION, AND A PLURALITY OF PLATE BAFFLES DISPOSED WITHIN THE CLASSIFICATION PORTION WHICH DEFINE A BUFFER PORTION AND A GRAVITATIONAL SETTLING PORTION (C). THE APPARATUS STILL FURTHER COMPRISES A DEVICE FOR GENERATING A RISING VELOCITY OF A SLURRY CONTAINING FINE CRYSTALS IN THE GRAVITATIONAL SETTLING PORTION (C) BY DISCHARGING THE SLURRY SO THAT THE RISING VELOCITY OF THE SLURRY IS GREATER THAN A SETTLING VELOCITY OF THE FINE CRYSTALS AND AN OUTLET FOR DISCHARGING THE CRYSTALLIZED MATERIAL.
