The significance of standardizing employee behavior is to prevent and reduce problems in organic fertilizer production lines caused by such simple reasons;

3. Continuously discovering, preventing, and repairing natural degradation, allowing organic fertilizer production lines to be repaired in potential failure states: The significance of independent maintenance lies in the involvement of frontline employees in identifying problems in the first time, comprehensively standardizing production maintenance, advocating for the discovery and removal of six sources of activity, and a very important link is to solve the problem of the fault source;

4. Correct defective designs and carry out proactive maintenance with incidental improvements to the design and manufacturing defects of organic fertilizer equipment;

5. Prevent human degradation, avoid human damage, and prevent destructive maintenance;

6. Control any abnormal external conditions and accelerate the deterioration of organic fertilizer production lines.

No matter what equipment is used, it is inevitable that some malfunctions will occur. Perhaps due to equipment quality, improper use, or long-term wear and tear of parts, organic fertilizer production lines may also experience some malfunctions after prolonged use. Effective control measures for faults in organic fertilizer production lines, making judgments based on the situation, and timely maintenance.

Chicken manure fermentation organic fertilizer production line to increase farm revenue

fertilizer granulator Apr 6, 2023

The products produced by the organic fertilizer production line are based on fresh chicken, pig dung, mushroom dregs, and other organic-containing waste materials. They do not contain any chemical ingredients. They are rich in the Vatican, and chickens and pigs have poor digestion ability, which can only consume 25% of the Nutritional ingredients, and the other 75% of the nutritional ingredients in the feed are excreted with the feces, so that the dried product contains nitrogen, phosphorus, potassium, organic matter, amino acids, proteins and other ingredients. Chicken manure fermented chicken manure not only created economic benefits for the company, but also made a huge contribution to human environmental protection projects.

The company provides large, medium and small biofertilizer project, which have the following characteristics:
1. Simple structure and easy operation. The use of some beneficial microorganisms can promote the rapid decay of organic waste such as animal manure, and adopts a unique trough continuous aerobic fermentation technology to make organic waste quickly deodorize, sterilize, and mature in a short period of time. The purpose of recycling and reducing the amount of processing and saving the fermentation site, the fermentation cycle is 8-10 days, reducing the energy consumption in the fermentation process, and making the quality of the fermented materials and products more stable.

2. During the fermentation process, automatic control of the number of times the fermented material is turned over. Under the action of forward and horizontal walking power, the stacker auger continuously throws, breaks, drops the ground and produces the fermented material to the rear of the fermentation tank. A certain displacement causes the material to move back regularly and equidistantly in the tank, thereby forming a continuous aerobic fermentation process.

3. The design of multiple tanks under the function of the lift truck reduces equipment and facilities investment and realizes innovation in large-scale production.

how to reduce dust in organic fertilizer production line

fertilizer granulator Mar 31, 2023

Organic fertilizer production equipment in the process of processing organic fertilizer, will produce a lot of dust, if not handled properly, will cause serious dust pollution. However, the organic fertilizer production line of our factory has less dust and more environmental protection, which is mainly realized by bag filter. Today, Huaqiang heavy industry small editor will explain how to reduce dust and environmental protection in organic fertilizer production line

The equipment in the production workshop should be completely closed at each blanking point, and the exhaust pipe should be installed. It ensures that the odor and dust in the organic fertilizer production process are leaked out, and the dust generated at the dropping point is then pumped into the bag filter by the induced draft fan. It is basically dust-free.

The inside of the bag filter is composed of several bags. The dust is filtered out by the bag, and the wind is discharged into the atmosphere through the bag. The bag filter is equipped with high-pressure blowing device in each bag. The dust on the bag is shaken off instantly by synchronous action of solenoid valve and time relay. Through the unloader at the lower end, the uniformly collected dust is discharged into the mixer, and the fertilizer is recycled. 

Fertilizer production line technology of chicken manure organic fertilizer particles

fertilizer granulator Mar 31, 2023

The design of chicken manure organic fertilizer pellet fermentation production process design includes:
1.Efficient compound bacteria and its propagation technology;

2. advanced raw material allocation technology and biological fermentation system;

3. the best special fertilizer formula technology (can flexibly design the best combination of product formula based on local soil and crop characteristics);

4. Reasonable secondary pollution (exhaust gas and depression) control technology;

5. Design and manufacturing technology of organic fertilizer production line equipment.

The more complicated process of chicken manure organic fertilizer production line is as follows: organic fertilizer raw materials (animal manure, domestic waste, dead leaves, biogas residues, waste bacteria, etc.) are fermented into a semi-wet material grinder for crushing, and then nitrogen is added. Phosphorus and potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) make the contained mineral elements reach the required standard, and then have a mixer to stir, and then enter the fertilizer granulator machine to get granules, after drying, screened by a sieving machine, qualified products are packaged, and unqualified returned to the granulator for granulation.

Among them, the reasonable mix of fineness of raw materials is very important for the organic fertilizer production line.

The fineness of the whole raw material should be matched as follows: about 100% to 60% of the raw materials account for about 30% to 40%, 60% to 1.00㎜ diameter raw materials account for about 35%, small particles with a diameter of 1.00-2.00㎜ about 25% -30% The higher the fineness of the material, the better the viscosity, and the higher the surface finish of the granulated particles.

However, in the production process, the use of ultra-high proportion of high-fineness materials is prone to problems such as excessively large particles and irregular particles.

The influence factors on the wear of the roller shell of the double roller granulator

fertilizer granulator Mar 31, 2023

The role of double roller granulator in organic fertilizer processing, such as mixed fertilizer. Regular hemispherical groove of roller skin is formed by squeezing each other. This extrusion pressure is inevitable in the wear of the double rollers of the double roller granulator. How to reduce the wear of roller sleeve should start with several reasons, and consider the corresponding countermeasures according to the wear reasons.

The influence factors on the wear of the roller shell of the double roller granulator

1. material factors
Roller extruder mainly processes dry powder materials. Because of the different hardness of the material, uneven force will be produced during extrusion and ball forming, which will increase the wear of the roller skin. From the material factor, another factor is the uniformity of the particle size of raw materials. Different sizes of raw materials can also lead to uneven force and wear of roller cover.

2. material factors of roller skin of double roller granulator
The roller surface of the roller fertilizer granulation machine is friction material and direct force. In the process of roller wear, friction and back extrusion pressure of materials can not be ignored. This force requires higher quality of roller skin, slower wear speed with good quality and faster wear speed with poor quality.

3. uniformity coefficient of feed
The center of parallel rod axis of the counter roller granulator is parallel to the surface of the roll skin. If the feeding is seriously uneven, one end of the feeding is more, and the other end is less, it will cause uneven force on both ends of the roller, increase the friction between the roller and the material, and cause the roller wear.

4. raw material moisture and pH
The roll skin is made of stainless steel. The organic fertilizer granulation machine has strong reaction to the acid and alkali of the material. The moisture and pH of the material are not good, which leads to acid-base corrosion on the surface of the roll skin and damages the roll skin.

5. work operation injury
If the operation is not in accordance with the operation procedures, the gap between rollers is not adjusted in place, or the feeding of the roller granulator is unreasonable; the other is that the material is not clean and contains impurities such as iron and sulfur. The color of the roller skin is seriously damaged.

Fertilizer granulator for wet granulation of organic fertilizer

fertilizer granulator Mar 31, 2023

Huaqiang heavy industry produces wet fertilizer granulation machine: disc granulator, drum granulator, organic fertilizer wet granulator and new two in one granulator. The main difference between these kinds of fertilizer granulators lies in the different raw materials and methods.

The moisture in wet granulation is the key factor to form the liquid bridge between the original particles. The pre wetting of powder before agglomeration is helpful to the formation of micronuclei and the quality of granulation. However, the amount of water added in different powder materials and granulation methods is also different, which is generally determined by experiments.

The new two in one organic fertilizer granulator is specially used for the granulation of organic fertilizer. The new two in one organic fertilizer granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously realize the mixing, granulation, spheroidization and densification of fine powder materials in the machine, so as to achieve the purpose of granulation. The particle shape is spherical, the sphericity is ≥ 0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is ≥ 90%. The size of the particle diameter can be properly adjusted by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotational speed, the smaller the particles, and vice versa.

Application scope: This organic fertilizer granulation machine is especially suitable for granulation of light and fine powder materials. The finer the basic particles of fine powder materials are, the higher the sphericity of particles is, and the better the quality of pellets is. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc.

In the process of using organic fertilizer production equipment, if strictly abide by the precautions in the operation process, it will effectively improve the granulation rate, reduce energy consumption and prolong the service life of the equipment. So from the following aspects, we can adjust the disc granulator to make the fertilizer production reach the best state.

1. Strictly control the quality of powder

(1) It is strictly forbidden to have iron block, stone larger than 10 mm and wood block larger than 10 mm in raw material discharging and feeding of fertilizer production line. Rice bran and sand can not exceed the quality index, too much will seriously cause low output of disc granulator.

(2) According to the formula of NPK compound fertilizer, the quality of various raw materials such as chemical fertilizer should be carefully controlled.

2.Reform the new type of blade in the disc

The blade of disc granulator is good, and the size of the granule is uniform and beautiful. The blade is divided into front blade and rear blade, and there is no gap between the two blades.

3. The main technical key to operate the disc granulator

(1) Do a good job in the technical training of staff before operation, improve the technical quality and operation skills of workers.

(2) The particle size of compound fertilizer is 70-90 mesh.

4. Select and adjust the nozzle of disc granulator

(1) The working mechanism of the nozzle must be mastered when selecting the nozzle

According to hydrodynamics, it has been proved that the bigger the pressure is, the smaller the through hole is, and the bigger the droplet diffusion surface is. Under the same pressure, the spray hole of the nozzle is small and the droplet density is small, while the spray hole is large, the droplet density is high.

(2) How to choose the model and specification of the nozzle

The smaller (or larger) droplet of feed liquid is, the smaller (or larger) particle size is, and the lower (or higher) yield of fertilizer production line is.

The denser (or thinner) the droplets are, the more (or less) they are made and the higher (or lower) the output is.
