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-fired type, 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, to avoid direct contact between the material and the drying air.
Nov 24, 2020 The residence time of organic fertilizer in a rotary dryer is generally 22 min. Under the same conditions, the longer the dryer barrel is, the longer the material stays and the higher the thermal energy utilization rate is. Therefore, lengthening the dryer cylinder is very beneficial to make full use of heat energy. 2. Air volume of the dryer
Indirect rotary dryers. Indirect rotary dryers differ from convective-direct dryers in that heat is transferred to the wet product by conduction and radiation through the cylinder wall or through a series of tubes located circumferentially to the cylinder. Indirect rotary dryers use as heating medium hot gases coming from a combustion chamber.
May 13, 2020 Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium. The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum silicate. rotary kiln how to operating
