Mainly check whether the bearings of the cooler are damaged or not, periodically check the temperature, noise and vibration of the bearings of the cooler and fan, and the lubrication effect of each lubrication point, and take timely maintenance measures. Regular daily cleaning of the equipment to ensure that the shape of the equipment is neat, and then the equipment components of the cooler and other safety checks. The unbalanced impeller and rotor of the fan will cause the vibration of the bearing to heat up. In daily production, preventive maintenance is more important than fault maintenance.

In order to ensure the normal operation of NPK fertilizerdrying and the service life of the dryer, the maintenance of the basic components of the NPK fertilizercooler is indispensable.Rotary cooleris a widely used NPK fertilizercooling machine.Inspection and maintenance of NPK fertilizer cooler equipment In fertilizer production line, the NPK fertilizerhas a higher temperature after passing through the dryer, is easy to absorb moisture and agglomerate, and cannot be directly packaged, so cooling equipment must be used for cooling. If the fan vibrates in operation, the balance of impeller, bearing and anchor bolt should be checked. The main points of the inspection are as follows. In most cases, the bearing heating of the cooler is caused by excessive lubrication or insufficient lubrication.Fan. If necessary, stop check and take effective measures.Bearings and lubrication of coolers and fans. Usually these bearing faults develop very fast, bearing faults will lead to the shutdown of the NPK fertilizerequipment.

The daily maintenance of the basic components of the cooler mainly includes the daily inspection and cleaning of the equipment. Check all the fans according to the fan manual, and check the wear and tear situation and carbon steel threaded rods Suppliers eliminate the unsafe factors every time the machine stops. The spare parts which are about to be damaged and have no stock should be ordered as early as possible. The cooling machine has a large volume.

Therefore, periodic inspection of the cooler should be carried out as far as possible to repair worn or unreliable parts, so as to improve the operation rate and service life of the cooler.Fertilizer cooling is a continuous and high-yield project, and the production of NPK fertilizerequipment cooler is large. The debris collected in the dust collector also needs to be cleaned up in time to avoid affecting the drying and cooling system of theNPK fertilizerproduction line. In particular, the wear and tear of the fan in dealing with dusty air is much faster than that in dealing with clean air.The detailed production process of NPK fertilizer ,you can refer:Flow of NPK fertilizerproduction line
