產品特點/Product Features
具有分級功能的OSLO結晶器通常被用來生產希望具有較大顆粒的產品。晶體在過飽和液流中流化懸浮，為晶體生長提供了一個好的流場條件。系統過飽和度產生于外置換熱器，晶體生長區域設置在結晶器下部。過飽和液被送到結晶器底部，在上升的過程中穿過晶體床層，逐步消除過飽和，晶體逐漸長大。
通常我們將它設計成為一個具有大直徑的澄清區域的結晶器。消除過飽和后的溶液經過澄清后才被泵抽吸離開，去獲得新的過飽和。它的優點在于循環母液中晶體顆粒含量較少，從而大的降低泵葉輪和晶粒之間的接觸幾率，降低二次成核的速率，為培養大顆粒晶體提供必要條件。
OSLO Crystallizer is used for producing larger size crystals with its classifying function. The crystals are fluidized and suspended in a supersaturated liquid which provided an excellent flow field condition for crystals growth.The system supersaturation is generated from the external heat exchanger. The crystal growth region is arranged at the lower part of the crystallizer. Supersaturated liquid is delivered to the bottom of the mold and passes through the crystal bed as it rises. It gradually eliminates supersaturation and grows up.
We usually design it as a mold with a large diameter of clear area. After removing the supersaturated, the solution is clarified and pumped away to obtain a new supersaturation. The content of crystal particles in circulating mother liquor is less, thereby greatly reducing the contact probability between the impeller and the grain of the pump, lowering the rate of second nucleation providing the necessary conditions for the ction of large grain crystals.
