multiplies output per hour, in less space and less time—at less cost
COWLES SETS
The big-volume and high efficiency records of the Cowles Dissolvers are rapidlymaking these advanced machines all-around workhorses of chemical production. While the Cowles actually provides up to 2 0 times faster mixing action —it is simpler t o operate, takes less space than conventional equipment. And with records o f up t o several times the hourly volume of ordinary mixers, it operates with low maintenance requirements—and even lower initial cost. In all models, uniform results in high quality end products are completely proved.
Tip-up type for pilot plants and small production. Highly versatile 5.VT."
V e r s a t i l i t y is unchallenged f o r g a s - l i q u i d , liquid-liquid a n d solid-liquid applications such as: ULTIMATE DISPERSION. Breaks material down to ultimate particle size, quickly surrounding each particle with a film of liquid.
DISPERSION
EMULSION. Creates fine, extremely stable emulsions of the most difficult types, without pumps, targets or auxiliary equipment. WASHING & EXTRACTION. Picks up dense materials from tank bottom, imparts intense washing and scrubbing action. Result: shorter and fewer cycles, more efficient use of scrubbing component, better operation o f evaporators, filters, etc. REACTION. Acts efficiently in producing small crystal sizes. More efficient utilization of reactants gives higher yield, particularly in gassing operations. Speeds reactions, simplifies temperature control. Key t o efficiency: t h e " M u l t i - P h a s e " action of r e v o l u t i o n a r y Cowles I m p e l l e r
The first with variable speed for big batches. 510-VHV hydraulic lift unit.*
This unique, patented impeller takes materials through several action phases not produced by ordinary equipment. Material is thrown off at 60 mph speed from impeller vanes. Particle is thus sheared and smashed against particle in a zone o f intense "hydraulic attrition!* At the same time, the entire batch is kept in "total motion," returning to the impeller in a controlled cycle. Scientific details on request.
