Which working areas does the sludge dryer mainly consist of?

The sludge dryer is a device widely used in drying various types of sludge. During the entire drying process, it is not the entire device that dries some materials independently. It can be divided into several areas. So, how many working areas must it pass through during the drying process to complete it? Then we can talk about it in detail in the next link.

1. Material guide area: The wet sludge enters this area and contacts with the high-temperature hot air to quickly evaporate the water. The material is moved by the copying plate with a large guide angle, and it is introduced into the next working area without forming a bond.

2. Material discharge area: The drum is not equipped with a copying plate in this area. The material rolls and slides to the discharge port in this area to complete the drying process of the entire sludge dryer.

3. Cleaning area: The wet sludge is copied by the copying plate in this area to form a material curtain state. When the material falls, it is easy to form a phenomenon of sticking to the drum wall. In this area, since the sludge dryer is designed with a cleaning device, the cleaning device will very reasonably clean the material adhering to the inner wall. In this process, the cleaning device also plays a role in breaking the material agglomeration, thereby increasing the heat exchange area and improving the drying rate.

4. Inclined lifting plate area: The wet sludge in this area is in a loose state with low moisture content, and the material in this area is no longer sticky. After heat exchange, the material reaches the required moisture state and enters the discharge area.
