Several work areas in the slime dryer
During the drying process, the slime sludge enters the slime dispersing device of the slime dryer via the belt conveyor, and after the quick-opening block coal slurry enters the negative pressure slime dryer Divided into the following work areas:
The first is the guiding area of ​​the slime dryer. When the wet coal slurry enters this area and is combined with the high-temperature negative pressure hot air, it is quickly evaporated to a large amount of water. Under the copying of the large-conducting angle, the slime is not formed into a bond. Copy into the next workspace;
The second is the cleaning area of ​​the slime dryer. The wet coal slurry is copied and formed in the area of ​​the curtain in this area. When the material falls, the phenomenon of bonding the drum wall is easy to form. In this area, due to the design of the equipment, the cleaning device can be used. Quickly clean out the slime of the bonded cylinder wall. In this process, the cleaning device also breaks up the agglomeration of the material ball, thereby increasing the heat conversion area, improving the efficiency of heat and mass transfer, and improving the drying rate;
The third is the inclined mud board area of ​​the slime dryer. This area is a low temperature drying area. The slime has a low moisture loose state in this area. This area has no bonding phenomenon. After the heat exchange, the finished product meets the requirements. Moisture requirements, movement into the final discharge area;
The fourth is the discharge area of ​​the slime dryer. The drying main drum does not have a copy board in this area. The material slides in this area to the discharge opening to complete the drying process of the whole slime dryer.
