Using rotary kilns for high-temperature bulk solids processing
Rotary kilns are used extensively in the production of mineral products such as roofing granules, adsorbents, fillers, desiccants, molecular sieves and more. In these settings, rotary kilns help to remove impurities, modify physical and chemical properties, bond coatings and colors to base materials and more. Plastics-to-fuel (PTF) technology.
The FEECO Rotary Dryer Handbook
HOW ROTARY DRYERS WORK Rotary dryers use a tumbling action in combination with a drying air in order to efficiently dry materials. Most often, rotary dryers are of the direct configura-tion, meaning that the drying air is in direct contact with the material. Some dryers, however, are of the indirect type, whereby the dryer is heated externally,
