Disc granulator is part of the most important fertilizer equipment in organic&compound fertilizer production line. During the producing process, some problems may occur, which is inevitable even with the most advanced equipment. If problems can’t be solved in time, the performance of granulator machine will be affected, and both the normal production and the company profits will be damaged.

Common Problems in Disc Granulator Usage

1.Sometimes, the final granules are not uniformly shaped, which is the most common problem that may occur during the working process of disc granulator. In order to solve this problem, you should change the moisture content of raw materials. Then you should screen the raw materials by drying them, so that the size of the final granules can be controlled.

2.When it is put into practical use, the inclination degrees of disc is not easy to be controlled. This problem is the most common one in the usage of disc granulator. Usually, there are no exact regulations for the inclination degrees. You can adjust it according to the practical needs of your fertilizer production. By adjusting the bolt in the bottom of the disc or the position of the decelerator, the inclination of the disc can be changed flexibly.

3.While it is working, the electric current of the main engine may become unstable. Then how to solve this problem? The main reason that leads to this problem is the non-uniform material supplement or the damage of the shaft of the main engine. Sometimes, the damage of the heating ring of the granulator may also contribute to this problem. In order to solve this problem, you should check the machine thoroughly. Check the feeding machine, main engine and the shaft respectively. Make sure that there is nothing wrong with these parts, and then check whether the healers of different parts can work smoothly or not.

4. It is difficult to shape. In the process of molding of the spherical particle, besides the subjective factor of the raw materials ingredients, the fineness of the raw materials, the moisture content of the raw materials, the adding of auxiliary adhesive composition, the angle of the disc operation, the speed of the disk operation and so on are also the common problems which we might encounter. According to the above problems, we can do some improvement. Then, we can reach the desired value.

5. Batch-type operation. This kind of breakdown is usually caused by the damaged bearing, the weightlessness of the disc body, the abnormal of the motor voltage. Deeper investigation, and timely maintenance can rapidly eliminate the operational failure of the disc granulator.

6. When the moisture of the particles is on the high side, the output of the granulation will be lower. And it will block the disc fertilizer pellet mill machine of compound fertilizer device. The reason for this phenomenon may be the reduced pressure of reducing valve didn’t work or the hydrophobic interaction of the drain valve did not have effect. We should adjust the reducing valve, and the steam pressure should be 0.1-0.4MPa. Then the drain valve can play an important role in the hydrophobic interaction.

7. When it appears the axial cracks or radial cracks phenomenon of particles, and the percentage of powered pellets is higher, the yield is low. The reason of leading to this phenomenon may be the refining temperature cannot be reached. The degree of curing of raw materials is worse. It should be adjust to the refining temperature to increase the quantity of steam while quenched and tempered.

8. The main motor cannot be launched.
Reason: There is something wrong with the order of the drive. Check whether the blown fuse is burned or not. And the thread of the main motor also has problems.
Solutions: To driver again in accordance with the correct car sequence. Check sequence, check the circuit of the main motor, check the state of the relevant interlocking device which is related to the main motor, check whether the lub oil pump launched. If the main motor cannot launch, turning off the main power and waiting for 5 minutes to start again.

9. The starting current of main electric is too high.
Reason: High torque, heating-up period is short and a section of the heater is not working.
Solution: Using the hand barring when driving the car. Prolong the heat-up time or check whether the heater is normal operation or not.

Caution:
If the disc granulator has above breakdown, we can find the reason to carry out maintenance. When using the pan granulator, we would like to advice you some methods. First, you should check the machine. In order to avoid appearing the failure which may influence the normal job. The technology of disc fertilizer granulator is simple. When the machine has breakdown, we do not need to worry. As long as we are according to the rule to carry on, and do maintenance regularly, we can reduce the breakdown of the disc granulator.

Daily Maintenance

1.After utilizing the equipment, you should clean its inner part. Making sure that the portable power source and the socket are reasonably placed, so that they can be effectively used for the next time.

2.If the disc granulator is idle for more than one month, you should clean up the materials and ashes in its inner part. Then make sure that the constituent parts are uniformly placed, such as the fixed support, movable support and the flush pipe and so on. After that, you’d better place this whole equipment in the room lest it should be corroded by raindrops.

3.However, if it has to be placed outside, you should remember to cover the equipment and turn off the gates to prevent it from corroded by air.

Remember that regular checking and maintenance are the best way to prolong a longer service life of the fertilizer machine.
