The Power of Rotary Dryers: From Drying to Chemical …
Normally, a combustion chamber is found in directly heated rotary dryer designs, in order to stop material from coming into direct contact with the burner's flame. Indirect drying is the less efficient means for removing moisture from material during processing, though this method is used for certain niche applications for which it …
Direct-Heat and Direct-Fired Rotary Dryers
The combustion chamber is a static furnace that is mounted to the end of the rotary dryer, either at the feed or discharge end, depending on whether the dryer is co-current or counter-current. The burner is mounted onto the combustion chamber, keeping the actual flame out of the rotary drum itself, and therefore away from the material being ...
Industrial Rotary Dryer Design and Capabilities
Adding a Combustion Chamber. Adding a combustion chamber to an industrial rotary dryer offers numerous benefits for certain applications. While the primary purpose is simply to prevent material directly coming into contact with flames to protect its integrity, several other advantages exist. These include:

Indirect Drying vs. Direct Drying
Direct-fired rotary dryer (with combustion chamber) Indirect-fired rotary dryers are better suited for niche applications. Indirect-fired dryers are ideal for processing dusty, fine materials, or materials that cannot be exposed to oxygen or combustion gases during processing. This is commonly seen with highly combustible materials, organics ...
Rotary Dryers
A rotary dryer is one of the most popular types of industrial dryers composed of a steel cylindrical shell that rotates around a shaft (Mujumdar, 2006; Yliniemi, Koskinen, & Leiviskä, 1998).The cylindrical shell has a length of 5–90 m, a diameter of 0.3–5 m, and a rotation of 1–5.The wet material enters the cylinder from the upper part and is discharged from the …
