Agitated Mixing Tanks

Agitated mixing tanks are pressure-rated or atmospheric vessels designed to combine, blend, and homogenize liquids, solids, and gases through mechanical agitation. These versatile vessels feature integrated agitation systems optimized for specific mixing requirements, from simple blending to complex multi-phase operations requiring precise control of mixing intensity and flow patterns.

Why are Agitated Mixing Tanks Needed?

Agitated mixing tanks are fundamental to countless industrial processes requiring uniform product composition. Effective mixing ensures consistent product quality, complete dissolution of ingredients, uniform temperature distribution, and efficient mass transfer. Roben Mfg utilizes advanced CFD analysis to optimize agitator selection and placement for maximum mixing efficiency.

Frequently Asked Questions (FAQs)

What agitator types are available for mixing tanks?

We offer a complete range of agitator types including turbines (Rushton, pitched blade, hydrofoil), propellers, anchors, helical ribbons, and specialty impellers. Agitator selection depends on viscosity range, mixing objectives, and process requirements. Our engineering team uses CFD analysis to recommend optimal configurations.

How do you determine proper agitator sizing?

Agitator sizing considers tank geometry, fluid properties (viscosity, density), mixing objectives (blending time, suspension requirements), and power input. We use CFD modeling to verify designs and optimize performance before fabrication. This approach ensures first-time success in meeting mixing specifications.

Can mixing tanks handle viscous products?

Yes, we design mixing tanks for viscosities from water-like to extremely viscous products exceeding 1,000,000 centipoise. High-viscosity applications typically use close-clearance impellers such as anchors or helical ribbons with appropriate power input. Wall scraping may be incorporated for heat transfer enhancement.
