Humic acid fertilizer refers to the production of a large amount of humic acid, nitrogen, phosphorus, potassium and some trace elements required by crop growth and development by using different production methods of peat, lignite and weathered coal. Humic acid, as the raw material of organic fertilizer production equipment, plays an important role in agricultural production, such as stimulating crop growth, improving soil, increasing nutrients and strengthening soil microbial activities.

Varieties of humic acid fertilizer

1. Humic acid fertilizers can be divided into two categories: natural humic acid and artificial humic acid according to their sources. Among natural humic acids, they are divided into soil sodium humic acid (white) phytic acid, coal coal humic acid, Water humic acid and mold humic acid, etc. Humic acid can be made into solid particles by NPK fertilizer granulator.

2. Humic acid fertilizers can be divided into primary humic acid and regenerated humic acid (including humic acid in natural weathered coal and artificial oxidized coal) according to the production method.

3. Humic acid fertilizers can be classified into fulvic acid, brown fulvic acid and black fulvic acid according to their solubility and color in solvents. In the earlier literature, there were also names of grey fulvic acid, brown fulvic acid and green humic acid, which were actually separated from different solvents.

4. According to the natural binding state, humic acid fertilizer can be divided into free humic acid and (calcium, magnesium) combined humic acid. We provide humic acid processing equipment, disc granulator, grinder, dryer, etc.

5. Humic acid fertilizer can be divided into type A, type B (true humic acid), RP type and P type (immature humic acid) according to the humification degree of humic acid (such as absorption coefficient).

The working principle of the new organic fertilizer granulator: the new organic fertilizer granulator uses the high-speed rotating mechanical stirring force and the generated aerodynamic force to continuously realize the process of mixing, granulating, spheroidizing 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 0.3-3mm, and the granulation rate is 90%. The particle diameter can be adjusted appropriately according to the mixing amount of the material and the spindle speed. The lower the mixing amount, the higher the rotation speed, the larger the particles Small, and vice versa. Scope of application: This machine is especially suitable for granulating light and fine powder materials. The finer the basic particles of the fine powder material, the higher the sphericity of the particles, and the better the quality of the particles. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. In view of the particularity of organic fermented fertilizer and organic fertilizer raw materials such as livestock manure, manure, retting manure, green manure, sea manure, cake fertilizer, peat, soil miscellaneous fertilizer, three wastes, microorganisms and other municipal solid wastes, the particles are granules.

The qualified rate of granulation by this machine is as high as 80-90%, which is suitable for a variety of different formulations. The compressive strength of organic fertilizer is higher than that of discs and drums, and the ball rate is lower than 15%. The stepless speed regulation function of this machine can adjust the uniformity of particle size according to user requirements. This machine is suitable for the direct granulation of organic fertilizer after fermentation, saving drying process and greatly reducing production cost. Now this new type of organic fertilizer wet granulator is popular among users. The birth of new products, new production technology, energy saving and environmental protection are all trustworthy.

In a complete fertilizer production line, granulation is the key process in the whole production process. The productivity of organic fertilizer granulator, the strength and shape of granule produced by the granulator directly affect the quality of the final product.

In many fertilizer production enterprises, the most used fertilizer granulation equipment are drum granulator, extrusion granulator and disc granulator. Among the three granulation methods, the disc granulator machine is more suitable for the granulation of organic-inorganic compound fertilizer, and the effect is ideal.

Disc granulator machine is mainly composed of granulation disc, spray system, transmission device, bracket and so on. During production, the powder raw materials are conveyed by the belt conveyor to the granulation disc in the disc granulator. The rotating disc with an inclination of 50° rotates the animal material. When the material is brought to a certain height, its own gravity and inertia Under the action of the force, it breaks away from the disc and slides down along the arc track to complete the rolling required for granulation. At the same time, the liquid injected by the spray system will be evenly sprayed on the rolling material to agglomerate into granules, thus completing The whole granulation process, according to the principles applied in this granulation process, we can call it agglomerate granulation process. With the continuous addition of raw materials, the manufactured particles fall across the edge of the disk under the action of centrifugal force and fall into the belt conveyor equipment below.

As a mature model, the disc granulator has experienced the test of various materials. However, any equipment has its advantages and disadvantages. In the face of different raw materials and production processes, there are also corresponding models. In the actual NPK fertilizer production line, the selection of granulation equipment suitable for materials can make the whole fertilizer production process play a maximum benefit.

There are two common methods to deal with feces in farms
1. Drying treatment. It is the excrement dehydration to facilitate the use, mainly has the natural drying and the high temperature fast drying. Natural drying is to use sunlight to dry livestock manure; high temperature and rapid drying is to dry artificially through a dryer. The commonly used drum dryer can reduce the moisture content of chicken manure from 70% to 75% in a short period of time to less than 8%. However, there are some disadvantages such as the secondary pollution of odor discharged by the dryer and the poor fertilizer efficiency caused by too high treatment temperature.
2. Aerobic composting. Livestock manure contains a lot of organic matter and rich nutrients such as nitrogen, phosphorus, potassium and so on, which is a valuable resource for the sustainable development of agriculture. Therefore, aerobic composting of manure is widely used at present. According to the characteristics of manure raw materials and auxiliary materials, according to the carbon nitrogen ratio and moisture content required for composting, manure and auxiliary materials are mixed in a certain proportion. The fertilizer production machine properly controls the oxygen and temperature in the heap, so that the manure can be rapidly fermented to produce organic fertilizer. The advantages of this method are less odor, more dry, easy to package and apply. It can be used as soil amendment or organic fertilizer in agricultural production.

Steps of making organic fertilizer from manure 
1. Raw material ingredients: chicken manure, pig manure, cow manure, biogas residue and other animal manure or raw materials that can be fermented or have fertilizer efficiency after treatment are equipped in a certain proportion (according to market demand and local soil test results).
2. Mixing of raw materials: Stir the prepared raw materials evenly to increase the uniform fertilizer efficiency content of the overall fertilizer particles.
3. Raw material granulation: Feed the uniformly stirred raw materials into the fertilizer granulator machine for granulation (rotary granulator or extrusion granulator can be used).
4. Granule drying: The granules made by the granulator are sent to the dryer to dry the moisture contained in the granules to increase the strength of the granules and facilitate storage.
5. Granule cooling: The temperature of dried fertilizer granules is too high and easy to agglomerate. After cooling, it is convenient for bagging storage and transportation.
6. Particle classification: The cooled particles are classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out.
7. Finished film: Coating qualified products to increase the brightness and roundness of the particles.
8. Finished product packaging: Pack the coated particles, which is the finished product, in a ventilated place.

The extrusion granulation method requires less equipment for double roll granulation machines, resulting in a relatively low project investment. The scientific research conducted by the International Fertilizer Development Center (NFDC) in developed countries in 1987 showed that the annual yield of 12 × The project investment for 104t granular N, P, and K fertilizer equipment is only 50% of slurry granulation or chemical granulation, which is 20% less than steam granulation; Squeezing granulation does not require heating and humidification of raw materials, saving project investment and energy consumption. It can incorporate granulation with heat-sensitive raw materials such as potassium nitrate and some organic compounds as seasoning; No sewage or exhaust emissions during the production process, making it less prone to environmental pollution; The extrusion granulation production process is short and the actual operation is simple, which is conducive to completing the automation of production machinery and improving productivity; There are no special regulations on the characteristics and particle size analysis of the raw materials, so the raw materials come from a wider range and are more convenient for production and manufacturing. If the product promotion plan needs to be changed, it is more convenient and beneficial for small-scale and large-scale production of organic compound fertilizers; The particle size analysis of the product is uniform, with high strength, and it is not easy to cause concrete segregation or agglomeration.

The appearance design of the extrusion granulator is not as smooth as traditional methods such as disc granulator and slurry granulator for producing fertilizer pellets; It is highly likely to cause smoke and dust during the entire transportation process. But if a special process is added in the steps and the surface of the product is hard bottomed, improvement can be achieved. In addition, if chemical changes occur again between the seasoning components within the product particles, it is highly likely to cause particle fragmentation.

The roll extrusion granulation method is the entire granulation process that uses working pressure to immediately squeeze raw materials into finished products, especially when integrating into the granulation of thermistor raw materials. There are generally two types of extrusion machinery equipment: one is an elbow type granulator; Another type is a rotary roller extrusion granulator. The two types also have various forms due to their different structures. The water content in the feed of the elbow type extrusion granulator is generally 5% to 8%. After extrusion, cylindrical materials are obtained, and compound fertilizer products with a water content below 5% are obtained through refrigeration. The water content in the feed of the gelatinous rotary roller extrusion granulator can be lower, with overseas reports ranging from 0.5% to 1.5%. The strip shaped raw materials obtained through extrusion are crushed by the crusher, and small or angular compound fertilizer products are selected through two layers of screening. The crushed ultrafine powder is returned to the extruder for granulation and return, and the coarse blocks are then returned to the crusher for crushing. Because the moisture content of the product is low, there is no need to carry out drying.

The roller extrusion granulator has a wide range of applications and can granulate a variety of raw materials. Therefore, it is also known as the ammonium sulfate composite fertilizer dry extrusion granulator, two-layer roller extrusion granulator, potassium magnesium fertilizer double roller extrusion granulator, calcium chloride roller extrusion granulator, dry ammonium sulfate roller granulator, compound fertilizer roller granulator, ammonium sulfate granulator, and compound fertilizer extrusion granulator.

9. Finished pellet packaging machine (equipment price is about 24,000-65 million yuan): The manufactured fertilizer pellets are bagged into the seam according to the set weight of the packaging bag.

In the fertilizer production process, different materials can choose different organic fertilizer machine, and the price of different organic fertilizer machine is also different. The cost of the organic fertilizer machine depends on the organic fertilizer machine of your actual needs.

The roller granulator is a dry granulation process that uses pressure to agglomerate solid materials. This is achieved by kneading the material through two opposite rotating roller shafts, which are driven by a bias sleeve or hydraulic system. When solid materials are kneaded, the air between the powder particles is first removed to rearrange the particles, in order to eliminate the gaps between the materials.

The roller squeezing granulator kneads the material through two opposite rotating rollers. When solid materials are subjected to external forces from the squeezing granulator, the gas between the powders is first cleaned and recombined, which can clear the empty space between the materials. When the material is squeezed and kneaded by a granulator, the particles will deform or move, generating a strong van der Waals gravitational recombination. In the final stage of the kneading and granulation process, the kinetic energy composed of working pressure to provide kinetic energy to the system forms a hot spot at the point contact between positive ions, but the material melts. After the temperature decreases and the material cools, it forms a fixed and non deformable particle.

The roller is also the most easily worn accessory in the granulation operation of the roller granulator. As the main part of material granulation, the roller skin is gradually worn and produces uneven particles. How to reduce the wear of the roller granulator is the most important thing.

Severe wear on the roller surface can affect the production efficiency of the roller granulator and the particle size of the finished product. In severe cases, it is necessary to stop the machine and replace the roller surface with a new one. How to reduce material wear on the roller surface through multiple efforts during equipment use? The main reasons for severe wear of the roller skin of the roller granulator are as follows:

1. Uneven feeding can easily cause uneven wear of the roller skin.

2. It is directly related to the material of the roller skin itself. The roller skin with poor material has poor wear resistance, corrosion resistance, and short service life.

3. The surface shape, specifications, dimensions, and operating conditions of the roller can have an impact on the machine.

4. Affected by the hardness, size, and shape of the processed material. Materials that are too hard, too large, or too irregular can easily cause uneven wear of the roller skin.

The reason for the wear of the roller skin of the roller granulator is that during the physical granulation of the roller skin, the roller surface will gradually wear out. Therefore, it is necessary to ensure that the material is evenly fed into the granulator along the length of the roller. If the feeding is uneven, circular grooves will appear on the roller surface, affecting the normal operation of the granulator, and the product particle size is uneven. When feeding, the feeder not only needs to feed evenly and continuously, but its length should also be consistent with the length of the roller.

Long term operation of the equipment inevitably results in wear on the roller skin of the roller granulator, which requires us to regularly shut down for maintenance. If we can repair it in advance when the wear reaches a certain level, can we avoid the need to replace the new roller surface in the future?

When the roller granulator is granulating materials, the roller surface will gradually wear out, ensuring that the materials are evenly fed into the granulator along the length of the roller. If the feeding is uneven, circular grooves will appear on the roller surface, affecting the normal operation of the granulator, and the product particle size is uneven. When feeding, the feeder not only needs to feed evenly and continuously, but its length should also be consistent with the length of the roller.

The wear of the roller surface can also increase the discharge port, so it is necessary to adjust the movable roller. When adjusting, it is necessary to keep the two rollers parallel to each other to prevent tilting. A pair of roller granulator with movable rollers installed on the rocker arm or hydraulic compensation device, which automatically ensures that the axes of the two rollers are parallel when the movable rollers move.

There is a grinding wheel installed on the rack. When there are pits or grooves on the roller surface, the roller surface can be ground and repaired on the machine without removing it, or directly repaired on the roller surface. This requires the installation of a welding device on the granulator. Some roller granulators are equipped with an automatic axial reciprocating movement device for the rollers, which ensures uniform wear and tear on the roller surface.

Agriculture has always been a top priority, and now the country is promoting green ecological agriculture. How can this goal be achieved? Firstly, it is necessary to eliminate the use of fertilizers. Reducing the amount of fertilizer used can effectively control the situation of soil damage, and then increase the use of organic fertilizers. Organic fertilizers made using chicken manure organic fertilizer equipment are safer and more reliable than homemade farmyard fertilizers. Moreover, chicken manure organic fertilizers can supplement soil organic matter, protect the soil from being hardened, and naturally improve the quality of crops grown with more soil nutrients, This has driven the development of the market. The production process of chicken manure organic fertilizer is divided into early fermentation stage and mid to late granulation stage. The fermentation stage only requires a fermentation tipping machine or fermentation stacking machine, and there are many machines and equipment used in the granulation stage. Generally, it is necessary to purchase a complete set of equipment for granulation production.
