ANDRITZ pneumatic dryers
Ideal for drying particulate materials in compliance with stringent environmental and energy efficiency demands.

Experience with different materials
ANDRITZ has a depth of experience in drying all types of materials with several different drying technologies. ANDRITZ pneumatic dryers are used to dry biomass substances, such as bark, sawdust, hog fuel, and wood waste, after it has been pulverized to an acceptable size for pneumatic conveying.

Pneumatic dryers can be equipped with an integrated grinder and wind-sifter in order to reduce particle size during the drying process. This configuration is suitable for producing pulverized fuel for rotating kilns or for pulverized firing in boilers.

The use of flue gases as heat transfer and transportation media is preferable as it secures a low oxygen content and safe operation.
