What is rotary dryer?
Rotary dryers are a highly efficient industrial drying option for bulk solids by direct or indirect heating method. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.
Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium.
