Why Choose HENGMEI Double Planetary Mixer?

The Double Planetary Mixer consists of two identical blades that rotate on their own axes while they orbit the mix vessel on a common axis. The blades continuously advance along the periphery of the vessel, removing material from the vessel wall and transporting it to the interior.

Efficient KneadingTwo blades rotate and orbit, passing through every point in the product zone in only 36 revolutions around the vessel.
No Shaft SealsNo shaft seals, bearings or packing submerged in the product zone. Clean operation.
Multiple Blade DesignsAvailable with HV blades, rectangular blades or finger blades for different materials.
Vacuum CompatibleVacuum hoods sustain up to 29.5 inches Hg for degassing and vacuum drying operations.

How It Works

How Does a Double Planetary Mixer Work?

What It Does

The Double Planetary Mixer turns over thick, sticky or putty-like materials with great efficiency through a kneading action to the batch which smooths out its consistency and breaks up agglomerates. The same planetary agitation is useful for high-precision granulation and vacuum drying operations.

How It Works

Two identical blades rotate on their own axes while they orbit the mix vessel on a common axis. The blades continuously advance along the periphery of the vessel, removing material from the vessel wall and transporting it to the interior. In only 36 revolutions around the vessel, the two blades pass through every point in the product zone, physically contacting the entire batch.

FAQ

Common Questions

What is a double planetary mixer used for?

A double planetary mixer is used for mixing high viscosity materials like adhesives, sealants, silicones, putties and pastes. Two identical blades rotate on their own axes while orbiting the mix vessel, providing efficient kneading action for materials that cannot be mixed with conventional mixers.

What is the difference between a double planetary mixer and a sigma mixer?

A double planetary mixer uses two blades that rotate on their own axes while orbiting the vessel, providing efficient kneading for medium to ultra-high viscosity materials. A sigma mixer uses two sigma-shaped blades rotating at different speeds, ideal for very high viscosity materials like rubber and chewing gum.

Can the double planetary mixer handle vacuum?

Yes. Vacuum hoods sustain up to 29.5 inches Hg for degassing and vacuum drying operations. The vacuum cover is precisely machined to maintain a deep level of vacuum.
