The maintenance of fertilizer drying equipment directly affects its operation efficiency, service life and production safety. It is necessary to follow the three-dimensional system of "routine inspection+regular maintenance+special maintenance", and carry out maintenance work in accordance with the structural characteristics of equipment types (drum, paddle, fluidized bed, spray dryer, etc.).

routine maintenance

Material system: Check if the feed inlet is blocked and if the moisture content of the material is abnormal (to avoid excessive moisture from sticking to the equipment), ensuring uniform feeding;

Power system: Check the lubricating oil level of the motor and reducer (the oil level should be between the scale lines), for any oil leakage, abnormal noise, or excessive vibration;

Heat source system: Gas/steam heating equipment requires inspection of pipeline sealing (no leakage) and flexible valve opening and closing; Check the appearance of the electric heating type heating tube for any damage and ensure that the wiring terminals are securely fastened;

Safety device: Confirm that the temperature sensor, pressure switch, overload protection, emergency stop button, and other functions are normal, and that the fire-fighting equipment (dry powder fire extinguishers, fire blankets) are complete and effective.
