Agitated Vessels for Crystallization
Agitated vessels for crystallization are specialized process tanks designed to produce crystalline products through controlled supersaturation management while providing gentle mixing to maintain crystal suspension and uniform conditions. These vessels enable production of high-quality crystals with consistent size, purity, and morphology.
Why are Agitated Vessels Needed for Crystallization?
Crystallization requires agitated vessels that maintain uniform supersaturation for consistent nucleation and growth, suspend crystals without mechanical damage, provide controlled temperature profiles for cooling crystallization, and enable efficient crystal harvest. Mixing intensity directly affects crystal size distribution and product quality.

Agitated Vessels for Crystallization FAQs
How does mixing affect crystal quality?
Mixing intensity affects nucleation rate, crystal growth uniformity, and crystal breakage. Excessive shear breaks crystals, generating fines that broaden size distribution. Insufficient mixing causes non-uniform supersaturation and localized nucleation. Optimal mixing maintains gentle suspension with uniform conditions throughout.
What agitators minimize crystal damage?
Crystal-friendly agitation uses low-shear impellers (marine, retreat-curve), controlled tip speeds, and draft tube configurations that provide circulation without high-impact zones. Multiple gentle impellers may replace single high-intensity agitators. CFD analysis identifies and eliminates high-shear regions.
