Check for clogging, and if necessary, clean them regularly; check the nozzle wear of the equipment for timely replacement; check whether the pump leaks oil and whether the pressure is normal , Whether the oil level is normal, etc . See if the atomizing disk is in a balanced state, whether the bearings work normally and whether the lubricant is added correctly. In response to this phenomenon, the former solution is to check the cyclone separator to see if there is a gap, and whether the air tightness is intact; the latter solution is to increase the secondary dust removal appropriately., and clean the filter screens of the oil pipe, oil pump, and oil nozzle if necessary.
When users use the spray dryer, they often encounter some problems, such as the adhesion of wet powder on the inner wall of the main tower, the presence of a large number of impurities in the product, the serious powder running phenomenon, and the noise, etc.
Trouble three: Serious powder running phenomenon and low recovery rate of the product If there is a problem with the cyclone separator or the dust removal performance is low, powder running phenomenon is likely to occur. At present, spray dryers are mainly used for drying some heat-sensitive liquids, suspensions and viscous liquids, and also for drying fuels, intermediates, soap powders and inorganic salts, etc. The spray dryer is a device that can complete drying and granulation at the same time.
Fault 2: There are a lot of impurities in the product This phenomenon generally has three causes. For the feeding system, check the filters, pipes, valves, nozzles, etc. At this time, the user should stop working and clean the aggregates in the drying tower. It is worth noting that china printing machines factory in addition to the need to grasp the causes of common failures and maintenance methods, users need to pay attention to equipment maintenance in order to ensure the service life of the equipment. First, the feed speed of the material is too fast and the amount is too large to make it completely dry. Therefore, if the user finds that the equipment is noisy, these two parts should be checked.
