Working Principle
The working principle of lignite rotary dryer is as follows: 1. Material guide area: the wet material mud enters this area and contacts with high-temperature hot air to quickly evaporate the water. The material is moved by the guide plate with a large lead angle, and it will be introduced into the next work area if it does not form a bond. 2. Pick-up and cleaning area: The wet material is picked up by the pick-up plate in this area to form a material curtain. When the material falls, it is easy to form the phenomenon of sticking to the drum wall. In this area, because the equipment is designed with a cleaning device, the cleaning device is very reasonable. In this process, the cleaning device also plays a role in crushing the agglomeration of material balls, thereby increasing the heat exchange area and improving the drying rate; 3. Inclined lifting plate area: the wet slime is in a loose state with low moisture content in this area, and the material has no bonding phenomenon in this area. After sufficient heat exchange, the material reaches the required moisture state and enters the discharge area; The fourth is the discharge area. The drum does not have a copying plate in this area, and the material rolls and slides to the discharge port in this area to complete the entire drying process.
