Agitators

1. Paddle agitators
Paddle agitators consist of two flat paddle-shaped impeller blades that extend into the tank wall. They are used if a lot of axial and radial flow is not required. These impellers produce laminar low shear flow and are used for mixing, crystallization, dissolution and heat transfer of low viscosity liquids. They usually operate at low speeds and produce mainly tangential flow patterns. Auxiliary blades can be fitted to the paddles to enhance mixing of more viscous materials.

2. Anchor agitator
Anchor mixers utilize anchor-shaped impellers, usually U-shaped, which match the contour of the tank. They produce mainly tangential flow patterns, but can be fitted with angled blades on horizontal supports to produce axial flow.
These agitators are used for mixing and heat transfer of high viscosity liquids. Their impellers produce laminar, low shear flow, making them ideal for mixing shear sensitive media. Anchor agitators are one of the most economical choices for laminar flow mixing and are suitable for tanks with round or conical bottoms. The impeller design allows for a small clearance to the tank wall.

3. Spiral belt agitators
Spiral belt agitators are characterized by spiral impeller blades mounted on a shaft by means of a rod. These impellers are an alternative to anchor impellers and are designed to produce an axial flow pattern. They provide a larger fluid contact area, making it possible to efficiently mix fluids with higher viscosities.

4. Double helical belt agitator
The double helical ribbon agitator features two helical blades passing through the shaft in opposite directions. This design improves the mixing of more viscous fluids. They are also used in heat transfer applications and are considered to be the best impellers for high viscosity laminar flow. The impeller can be designed to have less clearance from the tank wall.

5. Spiral impeller mixers
Spiral impellers are low clearance devices with spiral blades mounted directly on the impeller shaft. They provide excellent top-to-bottom turnover and are used for mixing highly viscous and shear-sensitive media.

6. Propeller agitators
Propeller agitators produce mainly axial flow patterns, but they can also produce tangential flow. As the impeller blades draw the fluid in, the fluid moves down the length of the tank and accelerates. The inclination of the impeller blades affects how the fluid is deflected. These blades taper towards the shaft to minimize centrifugal force and maximize axial flow.

7. Turbine agitators
Turbine agitators are in between propeller agitators and paddle agitators. Compared to propeller mixers, turbine mixers typically have a larger diameter and combine centrifugal and rotary motion. Turbine agitators are used in emulsification and dispersion processes that require high speeds of media flow. They provide a good balance between flow and shear and typically operate at high speeds. These agitators can handle materials of various viscosities while maintaining high mixing efficiencies.

8. Mixers with backward curved impellers
The backward curved impeller is designed with three curved blades with rounded edges and corners, which are suitable for coating with glass. This coating helps to prevent corrosion and contamination, which is vital for industries such as food, beverage and pharmaceuticals. These impellers produce mainly radial flow, while axial flow is affected by the ratio of impeller diameter to tank bottom clearance.

9. Agitators with hydrofoil impellers
Hydrofoil impellers have two to four narrow, tapered and curved blades, with the three-blade configuration being the most common in industrial applications. The blade angle gradually increases from tip to hub, creating an axial flow pattern. These impellers are designed to maximize fluid flow while generating low shear and consuming minimal energy, making them more efficient than inclined vane impellers. Hydrofoil impellers are also more economical than propellers for large diameter tanks.

10. Agitators with dispersing blade impellers
Dispersing vane impellers are characterized by a disc with sharp outer blades or teeth designed to break up lumps of solids and viscous liquids into fine particles. The serrated design is commonly used in a variety of industries. Over time, the outer blades become sharper due to wear and tear with the media. These impellers operate at high speeds to create high shear and turbulence. Typically, dispersing blade impellers are made of durable materials such as carbide and stainless steel.

11. Agitators with spiral impellers
Coil impellers utilize springs as impeller blades to produce a predominantly radial flow pattern. The springs have high mechanical stiffness to overcome the resistance created by the solids at the bottom of the suspension during mixing. In addition, the coil impeller helps prevent solids from settling on the bottom of the tank.

Regular inspection and maintenance of your agitator will help keep your machine running at peak performance. To help you maintain optimal performance levels, check regularly for any signs of deterioration, such as rust or excessive wear. Performing frequent visual inspections, monitoring equipment vibration and temperature and ensuring adequate torque will help ensure a longer life for your agitator. In addition, completing regular maintenance (e.g. cleaning and lubricating parts) can reduce the risk of agitator failure.

The agitator is the spinning device inside the drum of a top-loading washing machine. Its purpose is to move the clothes through the soapy water and help them rub against each other during the wash to remove dirt and grime from the fabric fibers. Despite the growing popularity of front-loading washers, top-loading washers with agitators remain popular for their simple design.

The agitator is a spindle located in the center of a top loading washer. It is used to spin, agitate, rock and push the laundry around the drum during the washing process. These spindles take up a portion of the total volume of the machine, making it difficult for large items such as bedding and towels to move freely, thus reducing the overall efficiency of the machine. Agitator washers typically use more water than impeller washers and are therefore less energy efficient.
