When discharging the spray dryer, pay attention to blocking the discharging opening. The dried material contains a lot of moisture and is easy to stick together. If the material is stuck together during discharging, it will cause the material to block the silo opening. It will cause the material to be dried to not fall down, enter the dryer, and cannot be dried. In addition, in addition to the usual blanking, the operating engineer needs to adjust the dryer accordingly. A stirring device is installed at the blanking port, which can effectively prevent the materials from sticking together and blocking the silo.
Pay attention to the quantity requirements when feeding materials. The quantity requirements are mainly determined by the output of the dryer to be dried. If the output is not enough, too much feed is not conducive to the work of the dryer.
Humidity control during feeding, the humidity of different materials to be dried is different, some are high and some are low. When drying the materials to be dried, the humidity of the materials to be dried needs to be checked, and the corresponding feeding standards are used according to the selection of materials with different humidity.
In order to ensure normal operation, it is necessary to check whether the parts and fastening parts of the spray dryer are loose, whether there is abnormal sound, and if any faults are found, remove them in time, check some transmission mechanisms such as V-belts, chains, etc., whether they are deformed, loose or worn, and adjust them in time. Chain tightness, check whether the electrical start and stop devices are sensitive, accurate and reliable.
