This week’s photo shows a warped leaf seal. Extreme heat during a kiln’s operation caused the seal to curl away from the drum, and cool into this deformed shape. It was later replaced by a FEECO Customer Service Engineer. Leaf seals minimize air leakage into …
Rotary kiln air flow configuration is an important consideration in kiln design. Counter current and co-current are the different types of air flow options available, each offering distinct advantages and disadvantages. In co-current air flow configuration, the material and process gas flow in the same …
This week’s highlighted resource is a Slideshare presentation on the production of activated carbon through the pyrolysis of biomass. Processing biomass through pyrolysis can yield a variety of end products, from biocoal and biochar, all the way to activated carbon, with additional products in between. …
While plastic has improved our lives in innumerable many ways, it has also become an insurmountable waste management issue, threatening the environment around us. As the world demands change, many industry experts are looking to plastic pyrolysis, a form of advanced plastics recycling and recovery …

Rotary kilns, an advanced type of thermal processing equipment, are used to cause a chemical reaction or physical change in a solid material through the use of high temperatures. They are frequently utilized to carry out the following processes: Calcination– the process of heating a material …
In regards to rotary dryer use, retention time is the duration of time that a material must remain in the dryer to achieve the desired end-product characteristics. Retention time is an important consideration to the dryer design, and is defined by looking at the specific …
Rotary coolers offer an effective approach to cooling bulk solids exiting a rotary kiln or dryer, allowing material to safely move on to packaging, handling, or transport. These diverse industrial coolers are available in two primary configurations: convective (direct) and indirect water deluge, each with …
The performance of a rotary dryer is vital to maximizing process efficiency and capacity in any industrial process setting. While a well-designed dryer will yield few problems of its own, various factors can cause the performance of the overall drying operation to degrade. Process audits …
Retention time, also called residence time, is the amount of time that the material must be processed in the rotary dryer in order to achieve the desired results. The retention time required for a given application is determined through balancing the necessary process parameters – …
