Planetary Mixer
The Planetary Mixer is a heavy-duty, slow-speed, high-torque mixer designed for homogeneous blending of highly viscous materials. It features one or more agitator blades rotating on their own axis while simultaneously orbiting around the vessel's center, similar to planetary motion — ensuring complete material movement with no dead zones.
This mixer is ideal for batch-wise processing of thick pastes, creams, and doughs, commonly used in cosmetic, pharmaceutical, food, and chemical industries.
A planetary mixer consists of a mixing tool (like a blade or paddle) attached to a rotating arm inside a stationary mixing bowl.
- The mixing tool rotates on its own axis (like a planet spinning).
- Simultaneously, the tool revolves around the center of the bowl (like a planet orbiting the sun).
- This dual motion (rotation + revolution) ensures the entire batch inside the bowl is mixed thoroughly and uniformly.
- The bowl itself remains stationary (does not rotate).
Because the mixing tool moves throughout the bowl in this planetary pattern, it can reach all parts of the bowl, preventing dead zones and mixing the ingredients more efficiently.
