Rotary Dryer Versatility Rotary Dryer Design And

An 18 dryer drum is not the only option. Rotary dryer drums as small as 4 diameter can evaporate anywhere from 200 500-lbshr. Rotary drums much smaller than this have efficiency losses so an alternate drying system may be more beneficial. Using the same example above, with a product at 50 mcwb, a small rotary drum dryer can take ...

Heat of compression rotary drum dryers

Heat Of Compression Rotary Drum Dryers

The heatless desiccant dryer is the most expensive to operate as 15-20 of its rated flow capacity is consumed as purge air. The rotary drum dryer can lead to significant energy savings because of its unique design and controls. Even compared to a blower purge dryer, rotary drum dryers can save up to 50 of the lifecycle cost. Maintenance cost
