Previously, we looked at indirect fired rotary kilns in applications such as reactivating spent carbons, pulling valuable materials out of valueless carriers, and conducting thermal processes in inert environments. Now we will look at indirect fired rotary kilns in the application of processing finely divided solids. Indirect fired rotary kilns can be beneficial when the Read More…
Depending on the circumstances, indirect fired rotary kilns can have many advantages over direct fired rotary kilns. One such advantage is when the required thermal processing is best done in an inert atmosphere. As an example, most carbonaceous solids will combust when at elevated temperatures in the presence of free oxygen. High temperature processing of Read More…
In the thermal processing industry, rotary kilns are used to cause chemical reactions or state changes in varying materials. As discussed previously in Direct Fired Rotary Kilns vs. Indirect Fired Rotary Kilns: What’s the Difference, while direct fired rotary kilns and indirect fired rotary kilns use similar thermal processing principles, they are each beneficial in Read More…
Feeco International has had much success in the thermal processing industry, with their custom designed rotary dryers, rotary kilns, rotary calciners, and rotary coolers. Part of their success is owed to their lab, which has state of the art equipment and highly trained technicians to run tests that assist in determining custom engineered needs. One Read More…
In the thermal processing industry, often times a rotary kiln is used to process a wide variety of feed material – from waste sludges to high-value minerals. Within the rotary kiln industry, there are two major subsets: direct fired rotary kilns, and indirect fired rotary kilns. Both kinds of rotary kilns run on the same Read More…
