The Ross double planetary mixer lined with Teflon is reportedly ideal for high-purity applications, providing chemical and corrosive resistance where stainless steel is not compatible. Highly versatile, the double planetary mixer can reportedly process viscous pastes and dough-like materials as easily as it can prepare dry powder blends and wet granulations. It provides gentle but thorough agitation required by shear-sensitive gels and fragile fiber-filled mixtures. This mixer is also used for vacuum drying operations.
Pictured is a 2-gal double planetary mixer equipped with Teflon-coated high-viscosity (HV) blades and a Teflon-lined vessel interior. Removable Teflon scrapers for the sidewall and vessel bottom are also provided. The identical blades rotate on their own axes while orbiting a common axis, a planetary motion that reportedly results in predictable and efficient mixing.
