TT/TT-LL Drum Dryer

Application

Drying of wood particles, OSB strands, wafers, sawdust, bark, disintegrated seasonal annual crops and biomass

Description

Wet material is fed via a rotary valve into the rotating drum. Heat is transferred mainly through convection into the material. Drum Dryer TT-LL separates the dried material with cyclones from the air stream. On the upgraded model TT the drum releases most of the dried material by gravity through a discharge box. In the gas stream suspended fine particles are conveyed to the cyclone battery.
