Charles Ross Offers New Hybrid Planetary Mixer Models

Charles Ross & Son Co. (Hauppauge, NY) has added new sizes to its line of planetary dual disperser mixing systems, which is designed for high-viscosity and high-solids applications.

The company describes the hybrid planetary mixers as comprising four agitators-two planetary stirrers and two high-speed dispersers-all of which rotate on their own axes, while orbiting the mix vessel on a common axis.

The company says that compared to single-shaft dispersers and multishaft mixers consisting of agitators with a fixed axis of rotation, the Ross planetary dual dispersers’ agitators are independently driven and controlled to offer precise control over shear levels and flow patterns. As such, the mixers also operate over a wider viscosity range up to several million centipoise.

Pictured are two 200-gal planetary dual disperser mixers that can also function as classic double planterary mixers because the dispersers are easily removable.
