Here are some of the main features and functions of the double planetary mixer:

1. Mixing Principle: The planetary blades rotate around their own axis while rotating around the center axis to provide thorough mixing action. The dual rotating and pivoting vanes allow for efficient mixing of both low and high viscosity materials.

2. High Viscosity Mixing: The Double Planetary Mixer is particularly effective in mixing materials that are highly viscous or that tend to thicken or solidify during processing. The shearing and kneading action of the blades helps break up lumps and disperse ingredients evenly.

3. Versatility: These mixers can handle a wide range of viscosities, from sticky pastes to highly fluid mixtures. They are suitable for processing a variety of products such as creams, gels, doughs, resins, polymers and composites.

4. Uniform mixing: The double planetary mixing action ensures uniform distribution of ingredients throughout the mixture, minimizing the risk of unmixed pockets or uneven mixing. This helps to achieve product uniformity and quality.

5. Scalability: Double planetary mixers are available in different sizes and capacities, allowing them to be scaled up or down according to production requirements. This makes them suitable for small-scale laboratory work as well as large-scale industrial production.

6. Optional features: Some double planetary mixers may offer additional features such as vacuum capacity for degassing or deaerating mixtures, temperature control for heating or cooling jackets, and a variety of discharge options for easy removal of the mixed product.

Double planetary mixers are known for their rugged construction, versatility and ability to handle challenging mixing applications. They are widely used in industries where precise control of the mixing process and a high quality end product are essential.
