A planetary mixer turns one or two blades in an orbit around the vessel while each blade also spins on its own axis, so every point in the vessel is reached. It is used for putty, adhesive and paste. Here you will find how a planetary paste mixer works, where it fits against a sigma mixer and what to specify.
A planetary mixer for putty is a good fit when you want a machine that is easy to clean and can lift out of the vessel.
We help you choose the machine that fits your product, batch size and plant, with specification, commissioning guidance and operator training. IPCS (Indian Paints Consulting Service) guides the selection of planetary mixer, from machine specification to installation, commissioning and operator training.
Planetary Mixer overview
Planetary motion means the blades travel along the wall and through the centre of the vessel. This reduces dead zones in high viscosity products. Many designs lift the blades out of the vessel, which makes cleaning and changing vessels easy, and can be built with a jacket or vacuum.
A high viscosity planetary mixer is chosen when the product is too thick for a disperser but must be mixed without a lot of heat.
Paint production applications for Planetary Mixer
It suits thick products that are made in batches and changed often.
Planetary mixer vs sigma mixer: the planetary machine is easier to clean and good for many products. A sigma mixer kneads harder for stiff masses.
Technical specifications to review for Planetary Mixer
Ask for these in the quotation.
| Parameter | What to specify | Guide |
|---|---|---|
| Working volume | Net batch | Vessel is larger than the batch |
| Blade design | Number and shape of blades | Matched to product viscosity |
| Vessel handling | Fixed, lifting or trolley vessel | Trolley vessels make colour change easy |
| Drive | Orbit and spin speeds | Variable speed is useful for powder wetting |
| Jacket or vacuum | If needed | For temperature control or air-free paste |
| Contact parts | Stainless steel | Easy to clean between products |
Capacity and configuration choices for Planetary Mixer
Capacity is set by the net batch and the viscosity. Models run from small trial machines to production units. Share your product and batch size and we match the machine.
Installation & support for Planetary Mixer
Routine care
- Check blade clearance to the vessel wall
- Inspect the planetary gearbox and seals
- Clean the vessel and blades before the paste hardens
- Check the lift mechanism and safety interlocks
- Log batch times and repairs
What we confirm before we quote
We confirm product and viscosity, net batch size, vacuum or jacket need and number of colour changes before we quote. Foundation, utility and commissioning guidance follows the confirmed size, and operators are trained on your own product.
Frequently Asked Questions
What is a planetary mixer?
A planetary mixer orbits blades around the vessel while they also spin on their own axes, so the whole vessel is swept. It mixes thick pastes without dead zones.
Is a planetary mixer for acrylic wall putty a good choice?
Yes, when you want easy cleaning and frequent product changes. For very stiff masses a sigma mixer may knead better.
Planetary mixer vs sigma mixer: which should I choose?
Choose a planetary mixer for easy cleaning and many products. Choose a sigma mixer for stiff, sticky masses and tilting discharge.
Can a planetary mixer be used for texture paint?
Yes. A planetary mixer for texture paint can handle the sand and filler content and is easy to clean between colours.
What does a high viscosity planetary mixer cost?
Price depends on the batch size, the blades, vessel handling and options such as a jacket or vacuum. We quote after you share the product and batch size.
