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.
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.

Technical answers about selection, operation, materials, controls and application requirements.
Anchor Agitator in India is a mixing solution designed to create the required circulation, suspension, dispersion, blending or heat-transfer performance for its intended process.
It is used in process tanks or vessels where the product, tank geometry and mixing objective match the equipment duty.
Impeller selection depends on viscosity, density, solids, gas rate, shear sensitivity, tank geometry and the required flow pattern.
RPM, impeller diameter, power and torque are selected together using process properties, tank dimensions and the required mixing intensity.
Yes, when the complete operating range is included in the design basis and the motor, gearbox, shaft and impeller are checked at the worst condition.
Carbon steel, SS304, SS316, SS316L, duplex, coated steel and selected non-metallic constructions may be used depending on corrosion, abrasion and hygiene requirements.
Baffles, sealing and mounting depend on tank geometry, vortex risk, pressure, vacuum, chemical hazard and maintenance requirements.
Provide tank diameter and height, operating volume, density, viscosity, temperature, pressure, solids, process objective, material and seal requirements.
Premix Technologies designs Anchor Agitator in India from actual tank geometry, fluid properties, process duty and mechanical-design requirements.
