    Rotary Dryers: When is a Combustion Chamber Necessary

    This is frequently seen in industries processing low-value products, such as asphalt or low-grade aggregates. The flame presents no problem to the material and essentially flashes off moisture by direct contact, reducing the required retention time. Benefits of a Rotary Dryer With a Combustion Chamber

    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
