Agitated Crystallization Vessels
META DESCRIPTION: Agitated crystallization vessels from Roben Mfg, Inc. Custom fabrication for controlled crystal formation. ASME certified with gentle agitation for crystal quality.
Agitated crystallization vessels are specialized process tanks designed to produce crystalline products through controlled supersaturation and crystal growth while providing gentle agitation to maintain crystal suspension, ensure uniform conditions, and prevent crystal damage. These vessels enable production of high-quality crystals with consistent size, purity, and morphology.
Why are Agitated Crystallization Vessels Needed?
Agitated crystallization vessels provide the controlled environment essential for producing quality crystalline products. Agitation maintains uniform supersaturation throughout the vessel, prevents crystal settling and agglomeration, ensures consistent temperature for cooling crystallization, and promotes even crystal growth. Gentle mixing is critical to prevent crystal breakage that affects product quality.

Frequently Asked Questions (FAQs)
How does agitation affect crystal quality?
Agitation intensity directly affects crystal size distribution and quality. Insufficient agitation causes settling and non-uniform growth. Excessive agitation breaks crystals, generating fines and reducing yield. Optimal agitation maintains suspension with minimal crystal damage. We design gentle mixing systems using CFD to predict shear levels and suspension quality.
What agitator designs are best for crystallization?
Crystallization typically uses low-shear impellers such as marine propellers, retreat-curve impellers, or draft tube configurations that provide circulation with minimal crystal damage. Impeller tip speed is carefully controlled to prevent breakage. Multiple gentle impellers may replace single high-intensity agitators for sensitive crystals.
How do you control crystal size distribution?
Crystal size distribution is controlled through supersaturation management, seeding strategy, temperature profile, and agitation intensity. Proper agitation ensures uniform conditions throughout the vessel, preventing localized supersaturation that causes nucleation bursts. Our designs provide the mixing uniformity essential for tight size distributions.
