Maintenance method of spray granulation dryer

- Aug 15, 2020-

After a period of operation (usually around 600h), the spray granulation dryer needs to be inspected and maintained as necessary. For the feeding system, check the filters, pipes, valves, nozzles, etc., to see if there is any blockage, clean them regularly, and check the wear of nozzles for timely replacement. Check whether the material pump is leaking, whether the pressure is normal, whether the oil level is normal, etc. For the fan, check whether the shaft and bearing are lack of oil to generate heat, whether there is vibration, noise, etc., and if necessary, clean the fan blades and perform balance check on the fan blades. For the heater, check whether the heat pipe is normal, and clean the filters at the oil pipe, oil pump, and oil nozzle if necessary. In addition, you should also pay attention to whether the motors have heat, vibration, or abnormal noise, and whether the instruments and electrical appliances in the control cabinet work normally.


In addition, when the equipment is running for about 2 400h (usually during the shutdown period), the equipment needs to be partially disassembled and repaired by maintenance personnel.
