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-fire type,meaning that the drying air is direct contact with the materials.Some dryers,however,are of the indirect type,whereby the dryer is heated externallly,to avoid direct contact between the material and the drying air.
Rotary dryers are comprised of a rotating drum,into which the material is fed,in combination with the drying air.Flights,or lifters,pick up the material from the bed,carrying it over,and dropping it through the air stream to maximize heat transfer between the material and drying air.
Material is processed for a specified amount of time,referred to as the retention time,at the desired temperature,in order to produce a product with the required moisture content.
While rotary dryer are available in standardized models,designing a rotary dryer around the unique characteristics of the material and process needs will produce the best results and offer the most reliability.Various aspects of the dryer are considered during initial design in order to reach the exact desired parameters of the end product.
