Planetary Disperser and Discharge System Turnkey Package

February 22, 2013

Ross-PowerMix-and-Discharge-SystemThe new Planetary Disperser and Discharge System Turnkey Package from Charles Ross & Son Co. is designed for high-viscosity, multi-stage mixing requirements. The Ross PowerMix (US Patent No. 4,697,929) consists of a stirrer blade and a saw-tooth disperser, both of which rotate on their respective axes at different speeds while orbiting the mix vessel. The high speed disperser quickly incorporates powders, fibers, pellets and other solids into a liquid batch while the planetary blade continuously sweeps the vessel walls and bottom. The stirrer also functions to help move viscous material toward the saw-tooth blade and ensure uniform heat distribution. Because each agitator is independently controlled, flow patterns and shear rates can be fine-tuned at any point during the mixing cycle. This turnkey solution is utilized in a wide range of applications including pharmaceutical and cosmetic creams and foods such as cheese spreads and starch pastes.
