SWENSON WALKER CRYSTALLIZER

PRODUCT DETAILS

Description

Crystallization is the formation of solid particles within ahomogeneous phase. Its wide use has a two-fold basis, acrystal formed from an impure solution is itself pure andcrystallization affords a practical method of obtainingpure chemical substances in a satisfactory condition forpacking and storing. This operation involves both heatand mass transfer. Crystallization may be analyzed fromthe standpoints of purity and yield. Swenson Walkercrystallizer is a continuous type crystallizer. It is a Jacketed round bottom semi cylindrical trough open atthe top. Cooling water flows through the jacket. A ribbonmixer is provided in crystallizer trough, which rotates atlow rpm for agitation of saturated solution. The saturatedsolution is prepared in a tank fitted with heater and astirrer. This hot feed is fed at one end of the crystallizerand flows slowly towards the other end while beingcooled and is allowed to flow back in hot feed tankmaking the process continuous. The crystals sediments atthe bottom of the trough, and can be washed out at theend of process. The pump circulates cooling water andthe Instrumentation Rotameter isprovided temperatures at differentpoints. measures for flow measuring rate. the
