JZeul· Cowles Dissolvers Can Help You Solve Metallic Dispersion and Reaction Problems •
Big volume sodium and lithium dispersions finished in 30 minutes or less, particle size as small as 2 microns, with plant· proven Cowles equipment. Highest quality metallic dispersions can now be easily controlled and produced in big volume, making many reactions commercially practical for the first time. Key to the new method is the unique action of the patented Cowles impeller. With rim speeds of up to 6150 fpm, the impeller vanes create a zone of intense turbulence and hydraulic shear. The liquid is moved rapidly through itself until maximum dispersion is obtained. T h e Cowles thus gives several many very important advantages: Versatility — prepares material for many reactions under conditions not heretofore possible. Finer particle size — gives maximum reaction surface to dispersed elements. M o r e complete dispersion — assures complete homogeneity of material. Greater speed — cuts finished dispersion time substantially. Cleanliness — self-cleaning impeller will not clog with metal. Safety — gives the close control necessary with highly active materials. Predictable results — laboratory and pilot-plant models provide results easily duplicated in larger models.
