If your rotary drum dryer is struggling to achieve uniform moisture content, and is still being operated inside design criteria, it may be time to consider a new flighting design. However, if your dryer used to process the same material at your current rates just fine, you may have flight damage – either from fire, rocks, or a slug of heavy
