Introduction of Double Planetary Mixer

The double planetary mixer is a high-performance mixing equipment widely used in various industries. It employs two types of mixers, each rotating on its axis while orbiting around the vessel’s central axis, creating a unique and highly efficient mixing action. This design ensures thorough blending of materials, particularly for viscous and complex mixtures. In addition, due to the equipped vacuum system, it can effectively avoid the generation of bubbles and foam while processing. This type of mixer is especially suitable for mixing, dissolving and mutual reaction from powder to high-viscosity and high-density materials.

Double planetary mixer offers exceptional versatility, making it suitable for applications ranging from pharmaceuticals and cosmetics to food and chemicals. SeFluid’s double planetary mixers are designed with state-of-the-art technology and precision engineering to deliver superior performance and reliability. By choosing SeFluid’s SDPM product series, customers can expect enhanced productivity, reduced downtime, and consistent product quality.

Working Principle of Double Planetary Mixer

The double planetary mixer is a versatile mixing equipment widely used for blending and mixing of materials. Its working principle involves the interaction of two planetary blades within a mixing chamber.

The mixer consists of a centrally located, rotating agitator, known as the “primary blade,” and a second set of blades, called the “satellite blades,” that orbit around the primary blade. Both blades are typically equipped with scraping edges to ensure efficient mixing and scraping of materials from the vessel walls.

During operation, the primary blade rotates on its own axis while simultaneously revolving around the center of the mixing chamber. This motion creates a powerful vortex effect, pulling the materials towards the center of the mixer. At the same time, the satellite blades rotate on their own axes and revolve around the primary blade, ensuring thorough mixing and dispersion of the materials.

The combination of the primary and satellite blade movements results in a unique mixing action. The primary blade provides high-speed agitation, while the satellite blades contribute to the overall blending and dispersion of the materials. Scraping edges of the blades help prevent material buildup on the vessel walls and ensure consistent mixing.

To further enhance mixing efficiency, the mixer can be equipped with various optional features such as high-speed dispersers, vacuum systems, heating or cooling jackets, and different types of vessel designs.

Advantages of Double Planetary Mixer

Double planetary mixers offer several advantages over other mixing equipment, making them a popular choice in various industries. Some of the key benefits include:

Efficient Mixing

The double planetary motion of the blades ensures thorough and uniform mixing, even for high-viscosity materials or those with varying particle sizes.

Versatility

The mixers can handle a wide range of applications, including kneading, dispersing, emulsifying, and homogenizing.

Scalability

Double planetary mixers are available in a wide range of sizes, from small laboratory-scale models to large production-scale machines. This scalability allows for easy adaptation to different batch sizes and production requirements, making it suitable for both small-scale research and large-scale manufacturing.

Optional Features

This type of mixers can be equipped with various optional features to enhance their functionality. These may include high-speed dispersers for additional shear mixing, vacuum systems for degassing or deaeration, heating or cooling jackets for temperature control, and different vessel designs to accommodate specific process requirements.

Sanitary Design

For applications in the food, pharmaceutical, and cosmetic industries, double planetary mixers can be designed with sanitary features such as crevice-free construction and polished surfaces.

Consistent Results

The design of this mixer type ensures consistent and repeatable mixing results. The scraping edges of the blades prevent material buildup on the vessel walls, minimizing product loss and ensuring consistent quality from batch to batch.
