Drying process of rotary kiln

Rotary Kilns. A rotary kiln is a continuous process designed specifically for drying, calcining, processing, or sintering bulk materials. The rotary kiln heated chamber is a long horizontal tube that is rotated with one end slightly elevated. The bulk material is continuously fed into the elevated end of the tube and cascades down the length of

    Pre-drying is used to remove most of the free water from lumber before it is placed in a kiln for final drying. In a predryer, lumber is stacked in a building where heat and humidity are controlled. The temperature is usually kept around 90-100 F (35 C). The lumber is dried to 20- 30% moisture content, and then placed in a kiln for final drying
