Question of the Week: How do you Combat Caking in a Rotary Dryer?

This article was authored by:

Jenny Seim
Technical Writer

Disparate materials can often clump together, or stick to the interior of the rotary dryer during the industrial drying process. This is referred to as unwanted agglomeration, or caking. Caking can occur for many reasons, but most often is the result of material characteristics that foster Continue reading →

Question of the Week: How do Material Limitations Affect Rotary Dryer Design?

This article was authored by:

Jenny Seim
Technical Writer

Some materials come with limitations that will steer the rotary dryer design process in one direction or another. For example, with materials that have the potential for combustion in certain settings, a direct fired dryer would not be the ideal option; an indirect dryer should Continue reading →
