What is a Blade Agitator?

Blade agitators are specialized industrial mixers that efficiently stir liquids or pasty materials using rotating blade arms. A gear motor reduces the rotational speed of the blades to allow efficient homogenization of both watery and viscous media. Blade agitators work with a radial flow pattern, ensuring thorough mixing, especially important when processing viscous substances such as suspensions, emulsions, or pastes.

Stainless steel blade agitators offer numerous advantages, making them indispensable in industries such as chemicals, pharmaceuticals, food production, and environmental technology. For a comparison with other common agitator types, we recommend this article where we’ve compiled an overview of all common agitator systems.

Advantages of Stainless Steel Blade Agitators

• High mixing efficiency: The rotating blades ensure even distribution and thorough mixing, especially in viscous or pasty substances.
• Low energy consumption: Blade agitators require less energy compared to other types when processing viscous media, helping reduce operating costs.
• Suitable for continuous operation: These agitators are built for continuous operation, as long as regular maintenance is performed.
• Versatile application: Our blade agitators are suitable for a wide range of uses, from intensive mixing of viscous materials to moving media over longer distances.
• Easy maintenance: Stainless steel blade agitators are easy to clean and maintain—an important benefit in industries such as food and pharmaceuticals.

Technical Features of Blade Agitators

Most blade agitators are equipped with multiple blades mounted evenly along the agitator shaft. These blades can be hygienically welded to the shaft or fixed with set screws. Other key features include:

• Blade length and geometry: Adapted to specific mixing requirements for optimal results with minimal energy input.
• Rotational speeds: Often equipped with adjustable speeds (e.g., 50 - 300 RPM) to match the mixing speed to the viscosity of the medium.
• Material selection: Stainless steel AISI 304 or AISI 316, depending on the application and required corrosion resistance.
• Mounting types: Direct mounting on a mixing tank, mounting on a bridge, or installation on a lifting stand.

What Mixing Tasks Do Blade Agitators Perform?

Blade agitators are especially well-suited for processing viscous media and pasty substances up to approx. 5000 mPas. In this range, blade agitators can perform a wide variety of tasks efficiently. They are particularly effective for mixing:

• Viscous liquids
• Suspensions and emulsions
• Homogenizing thick media

Buy New and Used Blade Agitators from Stock

At Behälter KG, we offer both new and used blade agitators that we can ship directly from stock without delay. Used blade agitators and mixing tanks with blade mixers are significantly more affordable than comparable new tanks, making them an attractive alternative to custom-built units with long lead times.
