Rotary Dryer Parts and Components Glossary

Rotary dryers use a tumbling action in combination with a drying air in order to efficiently dry materials. Most often, rotary dryers are of the direct-fired type, meaning that the drying air is in direct contact with the material. Some dryers, however, are of the indirect type, whereby the dryer is heated externally, to avoid direct contact between the material and the drying air.
