Video: Ross Double Planetary Mixers

The Double Planetary Mixer includes two 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. After one revolution, the blades have passed through the entire vessel; after three revolutions, most materials have been mixed; and after only 36 revolutions, the blades have contacted virtually the entire batch.
