In order to extend the new type of pelletzier effective use time as much as possible, bring better benefits to users, and solve more waste materials at the same time, management personnel should first develop a good habit in peacetime, and regularly invite professionals to do it. Check, once an abnormality is found, find out the cause as soon as possible and eliminate it. At the same time, some key components, such as rotating gears, should be maintained to ensure smooth operation.
Pay attention to check the bearing of the organic fertilizer granules making equipment, because it bears the full load of the equipment and directly affects the service life and normal operation of the equipment. Personnel need to make sure that they inject lubricating oil regularly, and the lubricating oil must be well sealed to ensure that the lubricating oil is clean. In addition, spare bearings are prepared so that when abnormal noises or abnormal heating are found, they can be replaced in time for maintenance.
In addition, some other parts of the equipment need to be inspected regularly, and even if necessary, the equipment can be disassembled, and then inspected and maintained. Pay attention to check the degree of wear and tear of other parts of stirring tooth making pellets equipment. When you find that a certain part may affect the normal operation of the equipment, it should be repaired and replaced in time. There are also some special parts that need to take anti-corrosion and anti-rust measures.

Disc type of granulator is one of the important equipment for organic fertilizer production, and its main working part is a rotating tilting disc. It is based on the principle of powder material agglomeration and granulation, so that the powder material with wet surface is continuously rolled or turned inside the disc granulator equipment, coupled with mechanical extrusion, prompting these powder materials to gradually form granules. Several parameters that will affect the granulation effect during the production of the disc granulator are: the diameter of the disc body, the height of the disc, the inclination angle and the rotation speed of the disc. Generally speaking, the diameter of the disk pelleting equipment is mainly determined by the output. The annual production capacity of the disc granulator with a diameter of 2 meters can reach more than 10,000 tons, and the annual production capacity of the pelletized disc with a diameter of 2.2 meters can reach more than 15,000 tons. Therefore, the choice of the disc diameter should be based on the design annual production capacity.
Plate pelleting machine for processing a variety of organic fertilizer raw materials.
Once the diameter of the disk pelletizer is determined, the height of the disc can basically be determined. Generally speaking, the larger the diameter, the higher the disc height. However, the height of the disc can also affect the time of the fertilizer on the disc. The particles generated on the disc will have a grading effect due to the difference in the coefficient of friction between the raw material and the disc surface. Small particles stagnate near the bottom of the disc, and larger particles are discharged beyond the edge, so that the higher the disc edge, the longer it takes to form a ball. If the disc height is too low, the ball formation time will be short, and the particles that go out will have a relatively small particle size. Therefore, on the one hand, the height of the tray can affect the size of the particles discharged from the pelletizing tray. On the other hand, it can also affect the output. Because if the material stays in the tray for too long, the discharge speed of the product will be slower, the larger the generated particles. The more non-compliant particles, and the lower the rate of ball formation. Therefore, it is very important to choose the height of the tray reasonably.
Used as fertilizer production equipment, the inclination angle of the pan making granules machine cannot be less than the natural angle of repose of the powdered material of 35°, otherwise the material will stick to the disc and rotate with the disc body. The increase in the angle of inclination and the increase in the speed can prevent materials from accumulating in the lower part, preventing drop and rolling up and down. However, the greater the angle of inclination, the faster the roll-down speed, and the smaller the overflow of particles. The most suitable inclination angle of the disc is related to the diameter of the disc. In other words, the inclination angle of the disc decreases as the diameter of the disc increases. This is because the final velocity of the particles moving along the disc surface increases with the increase of the diameter of the disc. To cause impact rupture, the inclination angle of the disc must be reduced.
It is suitable for granular compound fertilizer manufacturing line.
Since the granules will gradually grow up as they roll down along the surface of the disc, the more the number of times the material rolls in the disc per unit time, the faster the particles will grow up. That is to say, the working efficiency of disc granulator is proportional to the granulator’s rotating speed. Meanwhile, it is thrown to the edge of the disc due to the centrifugal force, these powders collide and fuse with each other, and The liquid phase is bonded together by the surface tension. Therefore, the speed of the rotation speed will affect the bonding and pelletizing process of the powder-grain fertilizer on the one hand. On the other hand, as the inclination angle of the disk increases. If the rotating speed of the disc is too slow, the material will accumulate in the lower part of the disc, and the drop and repeated rolling up and down will not occur, which will also affect the ball formation rate.
Disc plays an essential role in plate making granules machine.
As the speed of the disc pelleting equipment increases, its centrifugal force increases, which will make the granules close to the edge of the disc. In order to maintain the effective use of the disk surface area, the inclination angle of the disk must be increased while increasing the speed. As the inclination angle of the pan increases, the end speed of the particle rolling will increase accordingly, so the inclination angle of national pan should maintain a limit value to prevent the rolling and granulation of the material from causing damage. Therefore, the rotational speed of the disc is also a major influencing factor. Reasonable selection of the parameters of the granulation plate is one of the ways to increase the output, and it is also an important factor to reduce the cost of the product. In order to achieve a higher ball formation rate, various parameters should be adjusted appropriately according to specific conditions. Obtain the best granulation effect to increase production capacity.
