Anchor Impeller

Anchor agitators, also known as gate agitators or gate blade agitators, are a type of radial flow agitator commonly used in various industries. They are characterized by their anchor-shaped blades that create radial flow patterns within the mixing vessel. Here are some key features and characteristics of anchor impellers:

Due to their effective mixing capabilities in handling viscous materials and promoting solids suspension, anchor impellers are commonly used in industries such as chemical processing, pharmaceuticals, food and beverage, pulp and paper, water treatment, and various other applications involving high-viscosity fluids and mixtures.

Renewable Energy Production: In the renewable energy sector, anchor agitators are used in biofuel production and biogas reactors for efficient mixing of feedstocks and promoting anaerobic digestion processes.

CFD Assisted Impeller Selection

Computational Fluid Dynamics (CFD) helps our engineering team study how the impeller moves liquid inside a tank before finalizing agitator speed, impeller diameter, shaft position and baffle arrangement. For industrial impellers, CFD visualization is useful for reviewing circulation, velocity distribution, turbulence level and possible dead zones.

At Premix Technologies, CFD review supports practical agitator and impeller selection for blending, solid suspension, heat transfer, gas dispersion, slurry handling and process mixing applications. The video below demonstrates how flow lines and velocity distribution can be reviewed to improve mixing efficiency and reduce uneven circulation inside the vessel.

What We Check During CFD Review

• Flow pattern, circulation path and tank turnover
• Dead zones near tank bottom, corners and wall areas
• Impeller tip speed, velocity distribution and turbulence level
• Solid suspension behavior for slurry or process tank applications
• Baffle requirement to control vortex formation and improve turnover
• Power draw and mixing performance before final agitator sizing

Why It Matters for Customers

• Better impeller selection for the actual process duty
• More uniform blending, suspension and heat transfer
• Lower risk of stagnant zones, sedimentation and poor batch quality
• Improved confidence during scale-up from pilot to production tanks
• Optimized motor, gearbox and shaft design for reliable operation
