Rotary Drum Dryer
The rotary drum dryer continuously dries sawdust, wood chips and suitable bulk materials. Drum and supporting systems are configured for material properties, moisture, capacity and site conditions.
Product OverviewEquipment application and scope
A Rotary Drum Dryer continuously feeds wet, powdered or granular sawdust into a drying tube via a screw conveyor. As the material is transported and dispersed by a high-speed stream of hot air, the moisture in the wet material evaporates, resulting in a powdered or granular dry product. The system primarily consists of an air heater, a feeder, an airflow drying tube, a cyclone separator, and a blower.

Working Principle & ComponentsProcess and construction
The material enters the rotary drum dryer via a belt conveyor, where it is thoroughly mixed with hot air from the heat source. After heating to the point where moisture evaporates, the material and air are separated by a cyclone separator. The finished product is conveyed to the finished goods area, while the air and dust are filtered through a dust collector before being discharged.
