How to improve the drying efficiency and reduce the heat consumption of the rotary drum dryer has gradually attracted the widespread attention of the enterprise. In order to increase the production and energy saving of the drying system, when designing the drying line, it is necessary to find a reasonable allocation of the drying system; for the completed production line, the drying line should be improved with new technology. In the use of the rotary drum dryer, the most important thing is to ensure that the drying material is evenly distributed, the heat supply is uniform, and the heat exchange is efficient. The following highlights several key technical aspects that need to be addressed.
