Drying solid in rotary dryer

Feb 26, 2013 Experiments were conducted in a batch rotary dryer for obtaining the drying kinetics of a non-hygroscopic material with preheated air as the drying medium. The progress of the drying process was investigated for different temperatures and flow rates of the drying medium, initial moisture content of the solids, and rotational speed of the dryer

    May 01, 2016 In many industrial processes, rotary dryers are relied upon for high capacity, consistent drying of bulk solids — and for good reason. They offer innumerable benefits, both to the process and the product. One of the most prominent components of a rotary dryer is a large, rotating cylinder called the drum shell. Drying air or process gas flows through the drum in co-current or counter-current

    Rotary dryers work by tumbling and drying material in a rotating drum.The wet material enters the dryer from the front end, and when it passes inside the rotating cylinder, it is dried by effective contact with the hot air passing through the cylinder or the heated wall. The dried product is collected from the lower rear end of the cylinder

    Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock. Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated
