Dual-Shaft Mixers Are Versatile, Powerful
Mixer series reportedly powerful enough to batch dispersions, suspensions, and emulsions with viscosities up to several hundred thousand centipoise.
The latest line of dual-shaft mixers from Ross Mixers are said to be robust and versatile systems that are powerful enough to batch dispersions, suspensions, and emulsions with viscosities up to several hundred thousand centipoise. The custom-built ROSS FDA-3500 (photo) has a maximum working capacity of 3500 gal, a two-zone stainless steel dimpled jacket for heating/cooling, a 4-in. pneumatic discharge valve and an explosion-proof load cell system rated for up to 20,000 lb.

This multi-agitator system is equipped with independently controlled drives and is highly efficient at producing good turnover and imparting shear to a viscous batch. Powered by a 300-hp TEFC inverter duty motor, the high-speed disperser runs at tip speeds up to 5000 ft/min., inducing high shear forces while the 60-hp three-wing helical anchor agitator feeds product towards the disperser blade and ensures that the mixture is constantly in motion.
