What is a Wall Mounted Agitator?

A wall mounted agitator is a type of mixer that is installed directly onto the side wall of a mixing tank or vessel. Unlike top entry or bottom entry mixers, wall mounted agitators operate from a lateral position, offering greater flexibility in space-constrained environments. These agitators typically feature a motor, gearbox, support arm, and a mixing shaft with impellers that extend into the tank at a horizontal or inclined angle.

Wall mounted agitators are often used for blending liquids, dispersing powders, suspending solids, and maintaining uniformity in tanks where top access is limited. Their robust construction allows them to handle low to medium viscosity fluids, making them ideal for processes like fermentation, pH control, and batch mixing.

Key Advantages of Using a Wall Mounted Agitator

• Compact Design: Since the unit is mounted on the side of the tank, it frees up vertical space, which is especially valuable in facilities with height restrictions or multiple tank levels.

• Easy Access for Maintenance: The motor and gearbox are easily accessible from the side, allowing quick inspection and repairs without needing to dismantle the entire system.

• Improved Flow Patterns: When properly angled, wall mounted agitators create effective radial and axial flow patterns that enhance mixing efficiency and reduce dead zones in the tank.

• Energy Efficiency: With optimized impeller selection and motor sizing, these agitators deliver strong performance while minimizing power consumption.

• Custom Installation Options: Wall mounted agitators can be configured to suit various tank geometries and process requirements, including single or multiple units per tank.

These benefits make wall mounted agitators a smart investment for manufacturers looking to enhance productivity while reducing operational footprint.

Factors That Affect Mixing Efficiency

To fully optimize a wall mounted agitator, it's important to understand the factors that influence mixing performance. These include:

• Tank Design: The size, shape, and volume of the tank directly affect how fluids flow and mix. Flat-bottom, conical, and cylindrical tanks each interact differently with the mixer.

• Impeller Type and Position: The design and placement of impellers determine the flow pattern inside the tank. Common impeller types include axial flow, radial flow, and hybrid designs.

• Agitator Angle and Mounting Height: The angle at which the agitator is installed affects its ability to generate circulation and avoid vortex formation.

• Fluid Properties: Viscosity, density, and the presence of solids or gas bubbles all influence mixing dynamics. More viscous or complex fluids may require higher torque or multi-stage mixing.

• Motor Speed and Power: The motor's RPM and power rating must be matched to the application. Variable frequency drives (VFDs) offer control over speed and torque for optimized mixing.

• Process Requirements: Whether the application requires continuous or batch mixing, heating or cooling, or chemical reactions, the agitator must be configured accordingly.

Each of these elements must be carefully balanced to achieve efficient, consistent mixing. Consulting with a professional supplier like KEHENG can help you determine the ideal agitator configuration for your specific process.

Best Practices to Optimize Mixing with Wall Mounted Agitators

• Choose the Right Impeller: The impeller is the heart of the agitator. For wall mounted units, axial flow impellers are often recommended to generate strong circulation across the tank. For applications involving suspension of solids or dispersing gas, a pitched-blade or hydrofoil impeller may be more effective.

• Optimize Installation Angle: Mounting the agitator at a 15 to 20-degree angle from the horizontal axis can improve flow coverage, prevent vortex formation, and reduce sedimentation at the tank bottom.

• Use a Baffle System: In certain tank designs, adding internal baffles can further enhance turbulence and eliminate rotational flow patterns, improving overall mixing.

• Monitor Motor Load: Keeping an eye on the motor's load and power consumption can reveal signs of improper mixing or mechanical wear. A stable, optimized load improves energy efficiency and prolongs motor life.

• Employ Variable Speed Control: Installing a VFD allows you to adjust mixing intensity based on different phases of the process, such as blending, dissolving, or suspending. It also helps prevent shear-sensitive material degradation.

• Schedule Routine Maintenance: Regular lubrication, shaft inspection, and seal checks are essential for keeping your wall mounted agitator running smoothly. Dirty or worn parts can reduce efficiency and contaminate your batch.

• Train Operators: Ensure your staff understands how to use and maintain the agitator properly. Operator error is a common cause of inefficiency or premature equipment failure.

By implementing these best practices, you can significantly boost the effectiveness and reliability of your wall mounted agitator.

Applications Across Industries

Wall mounted agitators are versatile and support a wide range of industrial processes. Here are some common applications:

• Chemical Industry: Used in buffer tanks, reactors, and holding tanks to mix acids, bases, solvents, and slurries.

• Pharmaceuticals: Ensures uniformity in active ingredient dispersion and supports temperature-controlled mixing for sensitive compounds.

• Food and Beverage: Blends syrups, sauces, and emulsions in clean, hygienic environments. Stainless steel construction ensures food safety compliance.

• Water and Wastewater Treatment: Aids in flocculation, pH adjustment, and chemical dosing processes by maintaining homogeneity.

• Cosmetics and Personal Care: Mixes creams, gels, and lotions to achieve uniform texture and color.

• Paints and Coatings: Keeps pigments and resins evenly dispersed in storage and processing tanks.

Each application may demand different design considerations, which is why it's important to work with a supplier like KEHENG that offers custom engineering services tailored to your needs.
