First, the granular material processed by the organic fertilizer double-die granulator has a smooth surface and moderate hardness. During the processing, it can better maintain the internal nutrition of the material. It integrates a feeder, a mixer and a granulator. While feeding evenly, it can also carry out secondary fermentation of the material. The feeder is equipped with a governor, which adjusts the feeding amount according to the dry humidity of the material during production, so that the host is not easy to get stuck. The main machine integrates the ring die and the flat die, which is equivalent to the work of two granulators.

Second, the organic fertilizer double-die granulator has uniform particle composition and neat shape. The pore size of the particle size can be divided into 05, 06, 07, 08, etc., users can flexibly choose according to their own production needs.

Third, the mold, stirring and conveying blades of the double-die granulator are all made of corrosion-resistant stainless steel. Thereby effectively increasing the output and reducing the loss of equipment.

The following is an introduction to the correct use of the double-die granulator:

1. Fill the gearbox with 40# or 50# mechanical oil. If the temperature is low, add 70# or 90# gear oil before starting the machine;
2. Install the granulator smoothly, adjust the steering is normal, check whether the screws between the various parts are loose, pay attention to the gap between the pressing spoke and the mold in the season, the gap between the roller and the template is 0.1-0.3 mm, so that the machine It can be used after it is in a no-composite state and starts normally. The starting sequence is: 1, start the granulator; 2, start the feeder; 3, feed and adjust the speed of the feeder.
3. When the new double roller press machine is used for the first time, gradually add oily materials. The relay of chicken and duck is repeatedly squeezed to make the die hole lubricated and smooth, and then slowly add the materials to be processed and mixed for processing. If you feel that the resistance of the die hole is relatively large , When the output is low or no material is produced, the template can be repeatedly ground according to the method mentioned above, so that the die hole is lubricated and smooth before processing.
4. In the process of material processing, if there are more refined fibers, about 5% of water should be added. If there are more refined fibers in the mixture, the amount of water added can be appropriately reduced. Water will evaporate during the extrusion process. When adding compound fertilizer, attention should be paid to the chemical reaction of the material and the degree of dryness and wetness.
5. After the processing is completed, the feeder must be running at no load, and the host material cannot be accumulated. Pay attention to the minimum value of the current before it can be turned off. The correct sequence of shutdown is: stop feeding – close feeder – close granulator.

The above is the introduction of the use characteristics and correct use methods of the double-die granulator. You can refer to it. Only by mastering the scientific use method can ensure the high efficiency of production work and effectively prolong the service life of the equipment.

At present, the use of organic waste to produce organic fertilizer through biological fermentation has been rapidly developed, because it can realize the harmless and resourceful treatment of organic waste. However, most of the organic fertilizers obtained by biological fermentation are in the form of coarse powder or irregular small pieces, which are very inconvenient to use, especially unfavorable for large-area machine-sowing. Today, the FPC organic fertilizer manufacturer will explain how the organic fertilizer production line compresses and granulates the organic fertilizer.

The existing technologies for making the coarse powder or irregular small block organic fertilizer after biological fermentation into spherical granular organic fertilizer mainly include the following:

• Some manufacturers use traditional disc or drum granulation, and need to dry coarse powder or irregular small pieces of organic fertilizer (moisture <15%) and pulverize it into very fine (more than 100 mesh) powder , and then add binder and inorganic fertilizer, and the amount of binder and inorganic fertilizer added in the organic fertilizer cannot be greater than 30%. Although this method can be made into spherical particles, because the organic fertilizer in the processing process will be first Sufficient precipitation is crushed, water is added to granulate and then dried, repeated many times, so the organic fertilizer processing cost is quite high, and due to the low density of organic fertilizer, the particle strength is low, which is not conducive to storage, transportation and machine sowing.
• There are also some manufacturers who first dry the coarse powder or irregular small pieces of organic fertilizer to a moisture content of only 20-25%, and then use a flat die extrusion granulator or a counter-roll extrusion granulator to dry the fertilizer. The organic fertilizer is extruded into columnar or flat spherical particles. Although this method is more convenient to use, the fluidity is not very good, it is not suitable for machine sowing, and the appearance is poor and the appearance is not good.

• There are also some manufacturers who extrude coarse powder or irregular small pieces of organic fertilizer into short columnar particles with a flat die extrusion pelletizer(due to high moisture and high fiber content, the columnar particles also have certain characteristics. Plasticity), then polished and formed into spherical particles, and then the spherical particles are dried, cooled and screened to obtain qualified particles. In this method, the raw materials do not need to be treated, the order of moisture is reduced, and the production cost is greatly reduced, but this method also has some fatal The weakness is that the organic fertilizer is easy to be arched, easy to block and easy to bond equipment, and at the same time, the output is small and the power consumption of the extrusion process is high.

Therefore, in summary, the use of collision granulator to produce organic granular fertilizer has the advantages of low production cost, uniform product particle size, high strength, good fluidity, favorable for long-term storage and transportation, and suitable for machine sowing. That is to say, the performance of the products produced in this way is very good.

The dry-free extrusion granulation process of the pair-roller extrusion granulator has a wide range of applications in powder processing granules. Its characteristic is that it does not need to humidify or heat the material, and it can directly process the particles. It can be used for the processing of organic and inorganic fertilizer particles, and also for the processing of feed particles.

Utilizing the non-drying extrusion granulation process, no waste water or waste gas is discharged outside during the production process, and it will not pollute the environment. The extrusion granulation process is short, the operation is simple, and it is convenient to realize the automatic control of production and improve the production efficiency. There are no special requirements on the properties and particle size distribution of the raw materials, so the source of raw materials is relatively wide.

1. Add the qualified raw materials into the mixer according to the ratio requirements and mix them evenly.
2. It is transported to the disc feeder, and the metallic substance in the material is removed during the transporting process.
3. The material in the disc feeder evenly enters the extrusion granulator. The material is forced to pass between the two pressure rollers to be squeezed into flakes. The flakes are broken into pieces by the coarse crusher under the pressure rollers. Sieving. The materials on the screen continue to be crushed and sieved.
4. The semi-finished products are transported to the finished screening machine. The fine particles after screening are returned directly to the disc feeder. The large particles are crushed by the pulverizer and then returned to the disc feeder.
5. The qualified products after screening are transported to the automatic packaging scale for weighing, packaging, and storage.

The reason of wear of the shell of double roller granulator
Zhengzhou SX professional technicians will analyze the reasons for the wear of the roller shell on the compound fertilizer production line on the roller granulator

1. raw material moisture, pH

The roller sleeve is made of stainless steel. It reacts strongly with the pH value of the substance. Improper moisture and pH of the material will cause acid-base corrosion on the roller surface and damage the roller surface.

2. material factors

Roller extruder mainly deals with dry powder materials. Due to the different hardness of the material, uneven forces will be produced during extrusion and ball formation, which will increase the wear of roller skin. From the perspective of material factors, the other factor is the uniformity of the raw material particle size. Different sizes of raw materials also lead to uneven force and wear of roller sleeve.

3. feed uniformity coefficient

The center of the axis of the parallel bar of the extruder is parallel to the surface of the roll skin. If the feed is seriously uneven, one end feeds more and the other end is fed less, it will cause uneven force at both ends of the roller, increase the friction between the roller and the material, and cause the roller to wear.

Measures to reduce the wear of the roller shell in the compound fertilizer production line of the roller extruder:
In the process of pelletizing of the roller extrusion granulator, the roller skin is inevitably worn.

However, if used properly, it can effectively reduce the wear of the roller skin, thus extending the service life of the roller skin. According to the above factors, the following aspects can reduce the wear of the granulator.

1. for materials with high moisture content and high pH value, inspection and adjustment shall be carried out.

2. roller material, it is very necessary to select the cylinder cover with good material, wear resistance, torsion resistance and corrosion resistance.

3. in order to supply working materials, the uniformity of feed must be controlled to avoid wear caused by uneven axial force of roller.
Effective maintenance is an important means to reduce wear.

In conclusion, the damage factors should be avoided in the daily operation of the compound fertilizer production line from to the roller extruder. Therefore, manual and conventional use can reduce the wear of the pelletizing roller of extruder, prolong the service life and reduce unnecessary waste.
