Work process

The drying medium of the direct heat transfer drum dryer is usually flue gas. Downstream direct heat transfer drum dryer, its combustion chamber is at the same end as the wet material feed, and the hot air flow is in the same direction as the material. The wet material moves from the feed end to the discharge end, and the hot air It also flows out from the feed end through the discharge end under the action of the blower and the induced draft fan. The wet material is heated and dried by the hot air during the flow process. Counter-current direct heat transfer drum dryer, it is the wet material is fed into the dryer from the feed end, the combustion chamber is set at the discharge end, the material and the drying medium (hot air) move in opposite directions, and the material is in this process Medium heat and dry. Downstream drying is because the wet material fed into the dryer comes into contact with the higher temperature drying medium, the initial drying driving force is greater, and the temperature of the drying medium decreases as the temperature of the material increases. Therefore, it is suitable for materials that do not require high final moisture content (ie dryness). The discharged dry material has a lower temperature and is convenient for transportation. However, from the perspective of dust generation, fine materials are easily carried away by airflow, and the amount of dust is relatively large. Counter-current drying during the drying process, the drying driving force is uniform, which is suitable for drying the materials to be dried with strict requirements. The dust carried by the drying medium is filtered through the wet material zone, and the airflow contains less dust. The specific method of drying depends on the final requirements of the material to be dried.
