Used throughout nearly every process industry, ROSS Multi-Shaft Mixers are robust and versatile. Available in a variety of configurations, as either dual shaft mixers or triple shaft mixers depending on batch characteristics, Multi-Shaft Mixers accommodate a flexible range of shear input and viscosities up to several hundred thousand centipoise. The mixer’s basic design consists of two or more independently driven agitators working in tandem to ensure fine solids dispersion, efficient turnover and uniform heating/cooling.
A characteristic advantage of Multi-Shaft Mixers over typical single shaft devices is that they are closed systems and thus offer benefits in vacuum mixing. A simple dual shaft mixer design consists of a saw-tooth disperser blade enabling fast powder wet-out and dispersion, while the two or three-wing anchor supplies a steady exchange of materials from different parts of the vessel. In triple shaft mixers, a high shear rotor/stator head is typically utilized in addition to the disperser and anchor for high-viscosity emulsion applications.
