BARTLETT-SNOW'S
TECHNICAL APPROACH

your drying problems, too
• Ten years ago it was an adventure, this matter of rotary dryer design. Recommendations were made almost blindly, based largely on experience w i t h o t h e r —and frequently dissimilar materials. Guess-work bulked large in making decisions . . . But the Bartlett-Snow heat engineers have changed all this. Today "Technical Approach", —the a d v a n t a g e of mathematical formulas developed, tested and proved by our heat processing engineers has replaced guess-work—and luck—in Bartlett-Snow design. All factors—including those of surface e v a p o r a t i o n and diffusion, corrosion, abrasion, tendency to cake in cooling, the dust condition, and possible galvanic action are disassembled from each other, studied, checked. Findings are
verified when necessary, by running samples of the m a t e r i a l t h r o u g h an ingeniously arranged rotary test dryer. Thus all requirements of the problem become known,—and full allowance for all conditions can be made in the design of the equipment to be built. The advantage of this highly technical, highly accurate, mathematical solution of dryer problems is reflected only in Bartlett-Snow equipment. It's your assurance that the size and type, method of firing, pitch, rate of feed and all other specifications of the e q u i p m e n t recommended will be exactly suited to the r e q u i r e m e n t s of the serv i c e . L e t us h e l p y o u w i t h your next heat engineering problem.
