Abstract
A tumbler may be used as defluidizer, dryer, coater, classifier, or dynamic filter. The tumbler includes a rotatable drum that receives a solid/fluid slurry through an inlet chute. As the slurry travels through the drum, fluid exits the drum through a plurality of apertures in screens attached to the sides of the drum, while the solids continue along the drum's length until they reach one or more openings and exit the drum into an outlet chute. The outlet chute includes ridges that wrap around rings extending from the openings of the drum to prevent solids from escaping the outlet chute. To further dry the solids before they exit the drum, an air tube at least partially disposed within the drum is configured to introduce a flow of air into the drum.
