The reason of raw material precipitation during npk fertilizer granulation

When some compound fertilizer equipment production lines are processed by rotary drum granulator, they can dissolve the fertilizer into a certain proportion, but if the energy exceeds a certain amount, it will produce salt analysis and precipitate another substance.

Amino acids and zinc sulfate dissolve well in water, but when they are together, Zinc Sulfate Precipitates amino acids. The pH value of solution, part of the supply, metal salt dissolved in acid will produce precipitation and dissolve in alkaline medium, while some substances such as humic acid will form precipitation and dissolve in acid solution. Amino acids and humic acids can be analyzed by salt analysis, zinc, copper, iron, manganese and salt analysis. Therefore, it is more important to choose suitable raw materials for fertilizer production.
Fertilizer granulator granulation should consider whether the substances are compatible. Some substances cannot be mixed in the precipitation reaction, and precipitation occurs when they are mixed into water, such as zinc, copper, iron and manganese plasma. In the case of phosphate, borax will precipitate, the precipitate is insoluble in water, and the phosphate precipitates molybdate ammonia water, and these commodities cannot be produced at the same time. They not only produce precipitation, but also lose their fertilizer efficiency.
Raw materials are insoluble in water, so the proportion of fertilizer is blindly increased. At room temperature, the solubility of borax and boric acid in water is 30 kg / T, and most of them will precipitate. If several kinds of fertilizers are soluble in water, there is also a great demand. For example, zinc sulfate is soluble in water, potassium sulfate is soluble in water, and two kinds of raw materials are soluble in water, which can produce potassium sulfate crystals.

Organic fertilizer can promote the reproduction of soil microorganisms

Organic fertilizer can make microorganisms in soil multiply, especially many beneficial microorganisms, such as nitrogen fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, etc. These beneficial microorganisms can decompose organic matter in soil, increase soil aggregate structure and improve soil composition.

Microbes propagate rapidly in the soil, they are like an invisible net, very complex. After the death of microbial cells, many small pipes will be left in the soil, which not only increases the permeability of the soil, but also makes the soil soft and soft, so that nutrients and water are not easy to lose, increasing the soil’s water storage and fertilizer storage capacity, and avoiding and eliminating soil hardening.

The beneficial microorganisms in organic fertilizer can also inhibit the reproduction of harmful bacteria, so less chemicals can be used. If it is applied continuously for many years, it can effectively inhibit soil pests and save manpower, financial resources and pollution.

At the same time, organic fertilizer contains various active enzymes secreted by animal digestive tract and various enzymes produced by microorganisms. After these substances are applied to the soil, the enzyme activity of the soil can be greatly improved. Long term sustainable use of organic fertilizer can improve soil quality. If the soil quality is fundamentally improved, there is no need to worry that high-quality fruits will not be planted.

Organic fertilizer granulation equipment: granulation of mixed fertilizer is an important process of dry powder granulation process. It is not only related to the internal and external quality of products, but also to the size of output and cost. In addition to the physical and chemical properties of materials, the granulation process is closely related to the form and mechanical properties of granulation equipment. The main types of granulation equipment include disk granulator, drum granulator, double shaft granulator, extrusion granulator and spray granulator dryer.

Application of Organic Fertilizer Crusher in Life

The organic fertilizer crusher can be divided into three parts:

  1. Frame part: the normal operation of all machines can not be separated from a solid frame. The frame is welded by high-quality carbon steel plate and channel steel, and has passed strict product certification and specific process requirements, so as to achieve the purpose of using the machine;
  2. Rotor crushing part: the rotor structure of the machine is novel and the design is reasonable. The crushing effect is twice that of other products. The materials enter the crushing chamber from the feed inlet and are continuously crushed by double knives to meet the granulation requirements. There are thrusters and scrapers inside, and its materials will not stick to the wall.
  3. Transmission connection part: the machine is driven by flexible belt. The belt pulley and belt are driven by the motor and directly transmitted to the main shaft, which makes the main shaft rotate at a high speed to achieve the crushing effect.

As an important part of the organic fertilizer production line, the organic fertilizer crusher also has its own machine. The appearance of the pulverizer greatly reduces the crushing of manpower, and greatly improves the efficiency. During driving, the rotating knife loaded under the machine is used to stir, fluff and flip the chicken manure organic fertilizer raw materials. Leave a new strip pile on the road where the vehicle passes.

The appearance of the grinder has really made a great contribution to the organic fertilizer production line. The technology of the grinder integrates the crushing function of the material after fermentation. After the dehydration of materials, the grinder can effectively break the blocks formed by fertilizer in the fermentation process, which not only saves the work of the grinder, reduces the cost, but also improves the crushing efficiency, fundamentally solving the drawbacks of the grinder.

It meets the functional mechanism and process requirements of microbial fermentation and feces storage, and can effectively mix the viscous livestock manure with microbial agents and straw powder. In the loose material state, the deodorization of chicken manure takes about three hours, and the fermentation temperature can be controlled at about 60 ℃ for 4 days. The fertilizer can be formed in 7 days, and the number of beneficial microorganisms in the soil shall not be less than 30 billion/g. It is not only much faster than the traditional fermentation method, but also effectively prevents the production of hydrogen sulfide, ammonia and other harmful gases in the fermentation process, which meets the environmental requirements and can produce high-quality organic fertilizer.

Organic fertilizer compost fermentation turning machine supply factory

1. Organic fertilizer continuous trough dumper (single machine), models are 4m, 6m, 8m, 10m. The fermentation cycle is 7-8 days, the daily processing capacity is 800-1000 cubic meters, and the annual production capacity is 10000-20000 tons. Multi tank fermentation can increase production by 20000-50000 tons, and organic fertilizer can be fully fermented, which is suitable for granulation by rotary drum granulator.

2. Feeding at the feeding port and blanking at the other end. Daily feeding, daily blanking, daily processing. When the transfer section needs to be replaced after the transfer, the mixing shaft can be raised to quickly run the equipment to the transfer section.
3. The innovation of compost turning machine is to make full use of the deep pool design of underground space and the new technology of long-distance pile turning, so as to realize the large-scale harmless treatment of organic waste with limited surface area.

4. The composting dumper is compact in structure and advanced in technology. Some beneficial microorganisms are used to promote the rapid decomposition of organic wastes such as livestock manure. The unique tank type continuous aerobic fermentation technology is used to decompose, dehydrate, sterilize and deodorize organic waste rapidly, so as to achieve the goal of harmless and resource-based treatment. The decomposed organic fertilizer is processed by fertilizer granulator.
5. Intelligent automatic control of the fermentation material turning process. Under the action of the vertical and horizontal walking mechanism, the fermented material produces a certain pile-turning displacement in the tank, and returns to the tank regularly at equal distances, continuously and gradually, forming a continuous aerobic fermentation process. The stirring knife not only rotates evenly and oxidizes, but also has the function of crushing materials.
6. The electronic control system of the equipment is advanced and reliable, easy to operate, with manual and remote control. After the host starts to run, turn the rotary button to the “automatic” state, turn on the walk button, the flip machine starts to work, and the entire machine equipment runs longitudinally.

Ecological technological process and application effect of pig manure organic fertilizer production line

Pig dung and chicken dung are one of the most notorious stinky dung in the breeding industry. Pig manure should be a good farmyard manure, and a high-quality organic fertilizer resource for soil improvement. However, if fresh pig manure is applied directly, it will inevitably cause crop root injury, disease, grass damage and other negative effects. According to statistics, about 1000 pigs are sold annually, and about 1.2t of fresh pig manure is produced every day. If the natural composting and fermentation process is used in the past, there are several disadvantages: first, the composting time is long (4-6 months), and the effect is poor; Second, long-term stacking not only occupies the site, but also causes pollution to the surrounding environment. Third, the natural composted fermentation faeces are rotten, wet and stinky, which is difficult to transport and directly apply.

The pig manure harmless treatment organic fertilizer production line technology is analyzed by taking the manure treatment of pig farms with a breeding scale of about 1000 pigs as an example. The microbial fermentation strain used in this project is a highly effective composite microbial agent that can rapidly decompose livestock manure, crop straw sludge, agricultural by-product processing organic waste, etc., and has the following significant characteristics:

A Fast maturing organic solid stacking material, suitable for a variety of different composting substrates and different organic fertilizer dumping equipment;

B The content of effective living bacteria is more than 5 billion/g, and the addition amount is small and the cost is low. It only costs 8 yuan per ton;

C temperature rises quickly. When the ambient temperature is 0-5C, the composting temperature can rise to 55-70 “C within 48-72 hours;

D The composting cycle is short (7-10 days), which can save a lot of site and production costs:

E can quickly and effectively eliminate the peculiar smell in materials;

F has less nutrient loss, and the total nitrogen loss rate is less than 1%, which can effectively maintain the effective nutrient of compost. After fertilizer application, it can increase the number of microbial flora, improve the physical and chemical properties of soil, adjust the soil pH value, and has significant fertilizer effect;

G The high temperature of compost lasts for a long time, which can kill the bacteria and eggs in the raw materials of compost, make the compost reach the harmless standard in a short time, and become an efficient commercial organic fertilizer meeting the requirements of green food production.

H The amount of organic fertilizer produced by fermenting pig manure with BM strain is small, which can be used as base fertilizer: 80-150 kg/mu for cash crops such as vegetables, 80-100 kg/mu for grain, 80-100 kg/mu for tea trees, 1-3 kg/tree for fruit trees, and 0.5-1 kg/m2 for lawn.

Environmental protection application of organic fertilizer granulator in daily life

The organic fertilizer equipment is a good project for many people, because it not only conforms to the national environmental protection regulations, but also is an environmental protection machinery.

  1. Determine the size of the organic fertilizer equipment: for example, how many tons are produced each year, or how many tons are produced per hour, the price can be determined.
  2. Determining the shape of particles means choosing which granulator: powder, column, oblate or standard circle.
  3. Determine the configuration level of organic fertilizer equipment: different configuration levels, different prices of organic fertilizer equipment, different quantities of labor, and different stable and high yield of organic fertilizer equipment.
  4. Determine the level of environmental protection requirements: in places with low environmental requirements, dust reduction is generally selected, and the investment in organic fertilizer equipment is small; In places with high environmental protection requirements, heavy dust removal and ink dust removal are generally selected to meet the national air emission quality standards.

Matters needing attention when making granules by organic fertilizer granulator

(1) At least two powder silos to be granulated shall be provided so that the granulator does not need to stop when the formula changes.

(2) Before materials enter the granulator, effective iron removal device must be installed to protect the granulator.

(3) The organic fertilizer granulator shall be directly placed on the cooler, and the crusher shall be placed under the cooler.

(4) To prevent particles from falling from the bottom of the silo, a vertical spiral chute is installed in the silo.

(5) Finished products shall be packaged behind the finished product warehouse.

  1. Raw material receiving process oforganic fertilizer granulator. According to the type of raw materials received, different packaging forms and different transportation methods, different raw material receiving processes are adopted. No matter what receiving process, quality inspection and weight inspection of raw materials are required.
  2. After receiving the bulk truck of the organic fertilizer granulator, the raw materials on the bulk truck and tank truck will be automatically discharged into the receiving pit after being weighed by the ground scale. After the raw materials are discharged into the receiving pit, they will be transported by conveyor, bucket elevator and self moving scale, and then sent to the vertical silo for storage or directly sent to the silo for crushing or sent to the batching silo.

Operation requirements of drying equipment in organic fertilizer production line

Fertilizer dryer is suitable for the processing of organic fertilizer and NPK production line, and each structure of it is very important. Organic fertilizer dryer also has certain technical requirements when processing. So, what should be paid attention to when drum dryer is producing organic fertilizer?

The production equipment of chicken manure organic fertilizer is mainly composed of the following machines:
The first is the operation control equipment, the second is the dust removal and deodorization equipment, the third is the feeding equipment, the fourth is the hot stove, and the fifth is the chicken manure drying equipment. Chicken manure organic fertilizer equipment is mainly through the drying of chicken manure, and then add a certain amount of fertilizer accessories to produce organic fertilizer with chicken manure as the main raw material. In addition, it can also ferment chicken manure to produce organic fertilizer. This method requires equipment such as fertilizer granulator, pulverizer and dumper.
Chicken manure organic fertilizer dryer can dry 70% to 80% of the chicken manure to the standard of less than 13% through effective drying operations. Moreover, the entire operating process of the chicken manure dryer is A fully enclosed and fully enclosed state, which can play the role of environmental protection and reduce pollution.

 

The organic fertilizer mainly composed of chicken manure can be thoroughly removed, sterilized, purified, deodorized, dried and concentrated after processing and treatment by chicken manure dryer. It contains various nutrients necessary for crop production, including 2.6% of nitrogen, 3.5% of phosphorus, 2.5% of potassium, 16-25% of crude protein and 45% of organic matter. The treated organic fertilizer was used as raw material and granulated fertilizer was processed by rotary drum granulator.
The extraction and production of organic fertilizer by chicken manure dryer can not only greatly enhance the value of organic fertilizer itself, but also maximize the cost reduction.

Batch aerobic fermentation process of pig manure organic fertilizer equipment

Intermittent composting adopts the technical route of static one-time fermentation, which shortens the fermentation cycle and reduces the volume of compost. It is to ferment raw materials batch by batch. Generally, forced ventilation stack or fermentation bin with intermittent feeding and unloading are used. For materials with high organic content, forced ventilation is used at the same time, the composter is used to turn the materials intermittently, so as to prevent the composting materials from caking, make them mix evenly, and facilitate ventilation, So as to speed up the fermentation process and shorten the fermentation cycle. Intermittent fermentation devices include rectangular tank type fermentation bin, inclined bed type fermentation bin, vertical cylindrical fermentation bin, etc., all of which are equipped with ventilation pipes, and some are also equipped with mixing or turning devices.

Intermittent aerobic dynamic composting technology is characterized by layered uniform feeding and unloading. One layer of material is evenly discharged from the bottom of the fermentation bin every day, and one layer of material is evenly fed into the top every day. The fermentation bin has been controlled at a certain temperature to promote the reproduction of bacteria under the best conditions. The newly added pig manure is rapidly fermented and decomposed every day, and the matured pig manure at the bottom is output in time, which greatly shortens the fermentation cycle (the fermentation cycle of this process is 5 days).

In the fermentation process of organic fertilizer production equipment, the decomposition of organic matter will produce odor mainly composed of ammonia. During the process of putting various raw materials into the one-time fermentation facility, discharging compost from the one-time fermentation facility, and repeatedly operating in the secondary fermentation tank, odor and dust will be produced. As the decomposition of organic matter causes the temperature of raw materials to rise, a large amount of water vapor will be generated.

Methods of Improving Efficiency of Organic Fertilizer Crusher

The organic fertilizer grinder is mainly used for urban solid waste composting, rural straw waste, chicken manure, cow manure, sheep manure, pig manure and other special equipment, such as mining, coal mining, metallurgy and other industries. There are many things to pay attention to when using the organic fertilizer grinder. Because of its large demand, the most important thing is to improve the working efficiency of the grinder.

1、 Methods to Improve the Efficiency of Organic Fertilizer Crusher

  1. The selection of materials is the key. When selecting materials, pay attention to the hardness of materials. The more difficult the material is to crush, the more serious the wear of the equipment. The crushing speed is slow and the natural crushing capacity is small.
  2. The humidity of the material is the key, that is, when the moisture in the material is large, the material is easy to attach to the content of the grinder, and it is easy to block during the feeding and transportation process, thus reducing the crushing capacity. Therefore, before crushing, the moisture content of the crusher should be reduced as much as possible to facilitate the better work of the crusher.
  3. After crushing, the finer the material is required, the smaller the crushing capacity.
  4. Composition of crushed materials. The more fine particles contained in the materials before crushing, the greater the impact on crushing, because these fine powders are easy to adhere and affect transportation. For those with large fine particle content, they shall be screened once in advance.
  5. Material viscosity: that is, the greater the material viscosity, the easier it is to adhere.
  6. The better the abrasion resistance of the crushing parts (hammers and plates) of the crushing equipment, the greater the crushing capacity. If they are not abrasion resistant, the crushing capacity will be affected.

2、 Matters needing attention in the use of organic fertilizer crusher

  1. Before using the crusher, check whether the shape of the machine is damaged due to transportation and whether the random data is complete. Before turning on the power, please ensure that there are iron foreign matters in the cavity to prevent the knife from rotating, and manually rotate the flywheel for many times.

Never move the knife by hand to ensure safety. The motor can be started and put into production to ensure the correct rotation of the pulverizer host. Note: The main machine of the crusher shall not be reversed during operation, otherwise it will cause serious equipment accidents such as fixed knife injury and damage to left and right labyrinths.

2。 According to the material characteristics, the normal use time of the organic fertilizer crusher tools has its own length and short time. If there is wear, cut the knife in time. When installing tools, the rotary knife must be fastened. After the fixed knife is slightly fixed, adjust the 4-head knife adjusting screw to ensure that the rotating knife and the fixed knife maintain gaps of 0, 2-0 and 3, then tighten the fixed knife screw and lock the adjusting screw to complete the installation of the tool.

The mill has been running for about 500 hours. Please check the left and right main bearings and clean them if necessary. Add proper amount of grease or replace all grease and organic fertilizer grinding machine equipment to the allowable moisture value of bio fermented organic fertilizer materials of 25-55%. The crushing particle size meets the requirements of 50 mesh granulation.

Maintenance methods of npk fertilizer production equipment

How to effectively protect fertilizer equipment against aging and deformation. NPK production line equipment factory here to share a little tips.

First point: anti aging. The rubber or plastic products of fertilizer equipment are easy to be aged and deteriorated due to the effect of oxygen in the air and ultraviolet light in the sun, which makes the elasticity of rubber parts of fertilizer equipment poor and easy to be broken. For the storage of rubber parts of fertilizer equipment, it is better to apply hot paraffin oil on the rubber surface, put it on the indoor shelf, cover it with paper, and keep the fertilizer equipment ventilated, dry and free from direct sunlight.
Second point: Anti-deformation. The springs, transmission belts, long knife bars and other parts of the fertilizer equipment will be plastically deformed due to long-term stress or improper placement. For this reason, proper support should be provided under the fertilizer equipment; the machine does not bear the load; all the pressure or tension on the fertilizer equipment The opened spring must be relaxed; remove the transmission belt and keep it indoors; some easily deformed parts such as long blades should be laid flat or vertically hung; in addition, the removed organic fertilizer granulator machine parts should be prevented from squeezing and deformation during storage .
