Ross Double Planetary Mixers are offered in 4-, 5- and 10- and 25-gallon models for pilot-scale production of highly-filled pastes, dough-like materials, shear-sensitive gels, granulations and powder blends. These mixers are also used for vacuum drying of heat-sensitive applications at relatively low temperatures. Laboratory models start from half-pint size up to 2 gallons. Full-scale production models range from 40 to 1,000 gallons.
