There are two types of crystallizers according to the linear division of the inner wall of the section in the direction of casting: curved and straight; According to its overall structure, there are both sleeve and combination types for both curved and straight shapes.

The cooling water jacket composed of inner wall copper pipes, inner and outer water jackets, and foot rollers are its main components. The outer surface of straight or curved copper pipes consists of cooling water jackets, flanges, and sealing elements, forming a water supply and oil supply system. In order to ensure a regular appearance of the billet, 2-3 sets of foot rollers are installed at the bottom of the mold to improve the casting speed and prevent the billet from falling off square.

Crystallizer is a groove shaped container with a jacket on the wall or a snake tube inside, used to heat or cool the solution in the tank. The crystallization tank can be used as an evaporation crystallizer or a cooling crystallizer. To improve the production intensity of crystals, an agitator can be added in the tank. Crystallization tanks can be used for continuous or intermittent operations. The crystals obtained through intermittent operation are relatively large, but they are prone to forming clusters and entraining the mother liquor, which affects the purity of the product. This crystallizer has a simple structure and low production intensity, making it suitable for the production of small batch products such as chemical reagents and biochemical reagents.
