Do well the run-in test run of new engine or overhauled engine. According to the manufacturer’s technical requirements and test specifications, do a good job of running-in test, through testing and adjustment. Thus smooth and hard bearing surface and suitable fit clearance can be obtained, which provides good basic conditions for bearing load and fit parts’ service life. When after the test run of rotary pelleting machine, also should be based on the technical state of the machinery necessary technical maintenance.
Use qualified oil and water to add the internal of rotary type granulator. Bi of fuel oil and lubricating oil used by tractors and engines shall meet the prescribed quality standards, and appropriate oil brands shall be selected according to different seasons, regions and engine speed ranges.
Cooling water should be soft water with low content of calcium and magnesium minerals. The easy way to soften hard water is to precipitate it after boiling. (organic fertilizer production line) in general production practice. Every 1000 hours of engine operation, BI must wash the scale of the cooling system to improve the heat dissipation performance of the engine.
Ensure proper water tank and oil pressure. The cooling water temperature is generally between 70℃ and 90℃, and the normal water temperature should be kept between 80℃ and 90℃. Water temperature is too low, it is difficult to start, fuel can not be fully burned, engine power decreases, carbon accumulation increases.
The water temperature is too high, some parts of rotary making granules machine are easy to expand and deformation, and even the occurrence of cylinder liner piston stuck and burning tile accidents, but also make the lubricating oil thin, bearing oil film strength is low, wear and tear is accelerated, but also may reduce the fresh air volume. Engine power drops. To ensure that there is a normal oil pressure, that is, ensure that 2 ~ 3kgf/cm2. Oil pressure is too high, easy to leak oil, resulting in poor lubrication.
The oil pressure is too low, indicating that the oil supply is insufficient, the lubrication is not reliable, the wear is accelerated, and even causes the burning tile accident. When found that water temperature and oil pressure of drum granulating equipment is not normal, should be based on the relevant reasons, timely elimination.
The maintenance rules should be carried out carefully. According to the spirit of prevention first and prevention is more important than treatment, keep on the principle of, regularly to clean, fastening, tractors, motor inspection, lubrication, adjustment and change some of the oxidative damage of rubber, plastic parts and wear parts, on time, according to the requirements for technical maintenance, to ensure the normal function of each part, effective and reliable.

Because the pan granulatior machine has a very important feature is the ability to classify the size. In layman’s terms, when using a plate of type granulator, there is a fixed requirement for the size of the product. Because the friction coefficient of the feed powder and smaller particles is large, it is often in the bottom bin where the material is tumbling in the pan, and can rise to the highest position of the turntable before falling. The larger agglomerates are often on the surface of the bed, and the flow path is relatively short. During continuous operation, the largest agglomerates or the agglomerates with the required particle size of the product will overflow out of the disk from the surrounding baffle, while the smaller agglomerates and fine powder are still retained in the disk and continue to increase the particle size until It overflows only when the required granularity is reached.
Because the screening function of the pan type ofmaking granules machine is an important feature of its own, this point has a very important role in industrial production. In many occasions, the required products can be obtained directly through this function, without too much follow-up step strength, such as sieving. If the particle size requirements of the product are very strict, then as long as the rotating comb screen discharging machine is assembled on the disc granulation drum, a more uniform particle size product can be obtained.
Steam can be passed to the material layer in the drum to increase the temperature of the granulated material, which can increase the salt solubility of the granulated material, and realize the high liquid phase obtained under low moisture content to meet the liquid required for material granulation. Phasor, and can reduce the amount of evaporated water in the drying process.
When needed, ammonia can also be passed to the material layer in the drum to make the material react.
The inner wall of the drum type making granules machine can be lined with several rubber or polypropylene plates, and there are pores in the corresponding position on the cylinder. When the lining moves from the bottom to the top with the cylinder. At the same time, the lining sags due to its own weight, so that it adheres to the lining The material on the top falls due to gravity, which plays a role in automatically cleaning up the material.
During the operation of rotary drum pelleting machine, the operator can observe the material granulation at any time, so as to take timely measures as needed to ensure the normal operation of the system.

Relatively speaking, a factor that is relatively easy to cause the abrasion of organic fertilizer equipment is dust. The stirring teeth granulating equipment actually generates a certain amount of dust during operation and after discharge. If the cleaning and maintenance are not carried out in time, the dust will enter the various connections in the equipment, accumulating more and more over time. , The greater the friction at the equipment connection, and even the accumulation of germs, which will cause certain corrosion to the equipment and affect the performance of the equipment. Therefore, FFM organic fertilizer equipment manufacturer recommends that the staff need to do a comprehensive inspection and maintenance of the equipment when using organic fertilizer equipment.
In the process of organic fertilizer pelleting machine operation, our staff also need to pay attention to the management of the equipment connection. The long-term use of the equipment is a severe test for the equipment. Once there is a lag, the friction of the equipment will increase. Only a high degree of moisturizing can provide good power support for the operation of the organic fertilizer equipment, and the staff must develop a good habit of cleaning and maintaining the equipment regularly.
In addition, we need to pay special attention to the friction of the motor, otherwise it will affect the use effect of the organic fertilizer equipment. The staff should pay attention to checking the operation of the motor at all times. Especially before the load is running, the circuit of the motor should be checked, and if it is damaged, it needs to be updated immediately to ensure safe operation.
The disc granulation production line is suitable for granulation of various materials, organic fertilizer, organic-inorganic compound fertilizer, etc. It belongs to the universal granulator in the industry. In the course of use, the customer reported that the granulation yield was too low and the size of the particles was uneven. The problems found after on-site observation are summarized as follows.
The fineness of the material is not enough. (The degree of maturity is critical)
The material has too much moisture.
The material is not sufficiently viscous. (Calcium bentonite can be added)
The inclination angle of the disc is wrong. (adjustable)
The spray position is wrong, causing uneven particle size.
Plate pelleting machine for processing a variety of organic fertilizer raw materials.
The above are the conclusions that we have reached after studying the customer’s pelletizing production line. First of all, water spraying granulation does not require very high materials, but the requirements for the beautiful particles are higher. The finer the material, the drier, it is easy to produce millet-like particles during spraying. During the rotation of the equipment, due to The relationship between gravity particles and powder have an obvious division, the particles will have a rolling process from top to bottom, at this time the role of the pan type granulator is very important, we need to spray on the particles when we need large particles, small particles Dip it in powder form to become 2.5mm-5mm product granules. Generally, during granulation, the spray is placed between the granules and the powder, so that new granules are formed, and small particles can be made into finished granules. The granules from the drawing machine enter the dryer and heat up. Come out at about 560 degrees, enter the cooler, use the temperature difference to quickly remove the heat and moisture of the particles, then the moisture of drops below 25%, and then enter the small particles, and the finished particles. To separate the super-large particles, the most important thing is to return the sieved raw materials to the granulator (exceeding standard particles are crushed into small particles or powder by a chain mill), and the small raw materials becomes finished particles. Repeated this way, so that the yield will be greatly increased.

FFM Heavy Industry is a complete set of organic fertilizer production line, organic fertilizer granulator, organic fertilizer turner, organic fertilizer mixer, organic fertilizer grinder, organic fertilizer packaging. As a professional fertilizer machinery company, our experts analyzed that the problem that organic fertilizer equipment is prone to is noise. So if we encounter such a situation in production, how can we find and solve it?
In the mechanical transmission of organic fertilizer pelleting equipment, if there is an abnormality (often reflected in the form of noise), there will generally be changes in the amount of vibration and the vibration waveform. Based on the sound and vibration information (that is, vibration information), the vibration and vibration sources are detected and analyzed, and the deterioration state of the machinery can be quantitatively grasped without stopping and dismantling.
The fault diagnosis of machinery often uses mechanical vibration as a characteristic parameter
(1) The basic parameters of vibration The basic parameters of vibration include amplitude, frequency, and phase.
(2) The award rate is used to judge which part causes vibration for what reason. That is, by comparing the vibration frequency with the natural frequencies of rolling bearings, gears, shafts, rotors, couplings, etc. in mechanical transmission, the vibration can be found out.
(3) The vibration value is used to understand the degradation degree of the equipment. The vibration value is often used to specify the accuracy standard of vibration.

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.

The rotary drum granulating machine is a molding machine that can manufacture materials into specific shapes. The drum granulator is one of the key equipment in the compound fertilizer industry, which is suitable for the large-scale production of cold and hot granulation and high-, medium and low-concentration compound fertilizers. This equipment is used to perform necessary operations on the materials to be processed, steam and heating are used to adjust the humidity, which increases the temperature of the granulated materials themselves, reduces the water in the granulation, reduces the load of the dryer, and improves the work efficiency.
Rotary drum granulator for cold and hot granulation.
This machine adopts wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after the humidity is adjusted. Under a certain liquid phase condition, the material is made by the rotation of the cylinder. The squeezing force generated between the particles reunite into a ball.
First, each basic fertilizer is screened separately, and the screened material is crushed by a crusher and then screened. The under-sieve is sent to their respective hoppers. When the granulation system is in operation, the basic fertilizers are simultaneously sent from their respective hoppers to the feeding hopper via metering equipment, conveying equipment and lifting equipment according to the proportioning requirements. At the same time, the returned material enters the hopper together with the basic fertilizer through the lifting equipment. The basic fertilizers and returned materials are mixed to a certain extent in the process of transportation and lifting, but it is more ideal if a mixing device can be added. The mixture in the hopper is fed to the drum granulator at a certain feeding speed. At the same time, properly pass saturated steam under the material layer, which not only increases the temperature of the material, but also humidifies the material, which is conducive to granulation. If necessary, sprinkle a small amount of water or fertilizer solution on the material to maintain the maximum liquid level of the material to be granulated. The material forms a rolling material bed by the friction generated by the rotation of the drum granulator. The squeezing force generated by rolling makes the material containing a certain liquid phase agglomerate into small particles. These small particles become the core and adhere to the surrounding powder. Form larger particles. Since the drum granulator is generally inclined 1°~2.5° to the discharge end, the pellets slowly roll toward the discharge port while rotating with the cylinder. Qualified pellets leave the drum granulator and then enter the dryer for drying, and then go through screening, cooling, coating, packaging and storage. After being crushed, the on-screen material and the under-screen material are sent to the hopper as the return material and the basic fertilizer is granulated at the same time. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be realized.
Characteristics of the Rotary Drum Granulator
