This company recently completed three 1,000-gal planetary dual dispersers, reportedly the world’s largest change-can mixers of their kind. A dual-post hydraulic lift raises and lowers four sets of agitators―two pairs of helical high viscosity blades and two dual-blade high speed dispersers―into the jacketed mix can. Two 150-HP explosion-proof, inverter-duty motors drive the variable speed agitators. The disperser’s shear range and processing capability makes it useful for very challenging viscous dispersions up to several million centipoise.

All wetted parts, as well as the specially fabricated gearbox, are stainless steel 316L; exterior surfaces are stainless steel 304. In addition to the planetary blades and dispersers, scrapers for the vessel sidewall and bottom are also supplied for maximum temperature and mass uniformity throughout the mixing zone. All three mixers include PLC controls, a chiller, built-in vacuum pump and a custom CIP spray system for flushing the gearbox and mixer cover.
