How to get urea fertilizer coated?

Coated urea is a modified urea. So, why should urea be applied in the process of compound fertilizer production lines? There are two reasons:

1. Urea is a nitrogen fertilizer variety with the highest nitrogen content (n = 46%). In recent years, the actual effect of fertilization shows that urea is a kind of fertilizer with low utilization rate. Due to the large amount and low utilization rate of urea, the nitrogen loss caused by urea and the negative impact on the atmosphere and water environment are also large.

2. The reason for the low utilization rate of urea in agriculture is determined by the weak agricultural chemical properties of urea. The agrochemical properties of urea in soil are similar to that of ammonium bicarbonate. Soil cannot be absorbed and stored until it is absorbed and stored. At the same time of ammoniation, soil alkalization in micro area was also accompanied, which led to the increase of ammonia volatilization. The nitrogen content of urea is higher than that of ammonium bicarbonate, so the total volatile content of urea is higher than that of ammonium bicarbonate.

Material composition and processing technology of urea coating solution
The coating solution is a jelly composed of organic and inorganic substances. In addition to organic substances such as formic acid, a little salt forms of potassium (k), magnesium (mg), manganese (MN) and zinc (Zn) are added. Iron (FE), iron (b) and other nutrients. The coating solution is yellowish green with specific gravity of 1.17 ~ 1.18 and pH of 3 ~ 4.

Coating urea processing technology

Urea coating process is to use the coating solution and urea particle surface has a certain affinity, a small amount of solution evenly sprayed on the urea surface, and a small amount of penetration into the urea particles, the amount of coating solution per kg of urea is only 6-10 kg. With the help of hot drying and curing of urea, the coating solution can form a very thin film on the surface of urea particles after dry solid oxidation, which can be processed at one time.

We not only provide equipment related to urea coating production process, but also fertilizer granulator, NPK fertilizer granulator, extrusion granulator, rotary granulator, flat die granulator, organic fertilizer granulator, disc granulator, etc. Details go here.

Disc Granulator for Pellet Fertilizer Production

In cement, pulverized coal, chemical fertilizer and other industrial production fields, the granulation of powder or small non cohesive materials cannot be separated from the disc granulator.

Disc granulator has an irreplaceable role. Its rationality and advanced nature make it not only popular in fertilizer industry, but also talent shows itself in similar granulator equipment, and its application field is broader.

Structure of Pan fertilizer granulator

The structure of disc granulator is mainly composed of main body, main reducer, motor and transmission part.

Compared with the traditional equipment, the disc granulator is more scientific and unified, and can complete its own granulation work. High strength glass fiber, integrated arc design structure and three discharge outlets are designed to meet the needs of large-scale or large-scale granulation and ensure high granulation rate.

These structural optimizations improve the performance of the pan granulator to a new height, with the characteristics of uniform particle size, stable operation, weight and height reduction, which is convenient for operators to use.

The machine only needs a few people to complete all the work, effectively reduces the labor intensity, has strong flexibility, is suitable for NPK fertilizer production line, and can meet the needs of large material granulation.

Why people prefer to make organic fertilizer rather than chemical ones?

Chemical fertilizer has a rapid action and exists in various forms such as liquid and particle. Fertilizer is water-soluble, and plants can absorb nutrients immediately. Although this provides a quick nutrition and fast greening, it will never last. Only organic fertilizer can keep plants growing.
Chemical fertilizer can promote plant growth, but it has little effect on stimulating soil life, improving soil texture and improving long-term soil fertility. They can go into the water, but quick results come at a cost, too much use can burn your lawn and crops.

Organic Fertilizer Production Line

Because the nutrient of single chemical fertilizer is too simple to be suitable for crop growth, compound fertilizer is diversified at present. Most fertilizer plants use a pan type fertilizer granulator to process all the powder into granules.

What is organic fertilizer

Organic fertilizer is great for plants and soil. If used properly, it will not burn or damage plants. Organic fertilizer stimulates soil microorganism and improves soil structure. Soil microorganisms play an important role in transforming organic fertilizers into soluble nutrients that can be absorbed by plants. Organic fertilizers usually provide secondary and micronutrient requirements, but not in synthetic fertilizers.

NPK Fertilizer Production Plant

The content of N, P and K in organic fertilizer is lower than that in chemical fertilizer, but it can prolong soil fertility. Therefore, the effect of organic fertilizer on plants is usually more subtle. It may take a while to see the results, but the payoff is that plants take a long time to get nutrients and the soil maintains its fertility.

After fermentation treatment, the organic waste is treated by crusher, organic fertilizer granulator and drum dryer to become organic fertilizer.
With the continuous development of science and technology, pure chemical fertilizer and organic fertilizer are difficult to fully meet the actual growth requirements of different soil crops. Therefore, it is necessary for chemical fertilizer plants to use fertilizer granulator to produce various types of organic fertilizer compound fertilizer to improve soil quality, reduce environmental pollution and improve fertilizer efficiency.

Why is organic fertilizer production so popular?

The content of soil organic matter is closely related to soil fertility. Although organic matter only accounts for a small part of the total soil, it plays an important role in maintaining soil fertility. The manufacturer of organic fertilizer production equipment introduced six functions of organic matter to maintain soil fertility.

Compost Made from Organic Waste
Compost Made from Organic Waste

1. Provide nutrition for plants

Soil organic matter contains a large number of plant nutrient elements, such as N, P, K, CA, Mg, Sn, Fe and other important elements, as well as some trace elements. Soil organic matter releases a large amount of nutrients through the mineralization process to provide nutrients for plant growth; humus synthesizes humus and preserves nutrients; humus releases nutrients again through mineralization process, so as to ensure the nutritional requirements of the whole plant growth process.

2. Promote plants to absorb other nutrients

In the process of decomposition and transformation of soil organic matter, the organic acid and thermal acid produced by the decomposition and transformation of soil organic matter have a certain solubility to the mineral part of the soil, which can promote the mineral differentiation and is conducive to the availability of some nutrients. Some metal ions combined with organic acids can be retained in soil solution without causing precipitation and affecting its availability.

3. Promote plant growth and development

Soil organic matter, especially polyphenol functional group, can enhance the plant respiration process, improve the permeability of cell membrane, promote the rapid introduction of nutrients into plants, and promote the growth of plant roots. Soil organic matter also contains vitamin B1, B2, propionic acid, nicotinic acid, hormones, IAA (+) – Non-Ethylene diacetate), antibiotics (streptomycin, penicillin), etc., which can promote plant growth and enhance disease resistance.

4. Improve soil physical properties

Organic matter has many functions in improving soil physical properties. The most important and direct function of improving soil structure is to improve soil structure, promote the formation of aggregate structure, increase soil looseness, and improve soil air and water permeability. Humus is the main cement of soil aggregate. Hu mu in the soil rarely exists in free state. Most humus and mineral soil particles combine with each other. Through the mechanism of functional group and hydrogen bond, the organic-inorganic complex is formed by wrapping the surface of mineral soil particles in the form of adhesive film. The distribution of agglomerates is reasonable, the stability of large, small holes and water is strong, and the structure is good. In arid areas, organic matter can reduce the expansion and contraction of soil by increasing soil viscosity, and prevent the emergence of large cracks when the soil is dry.

5. Provide energy for soil organisms

Without soil microbes, there would be no biochemical processes in the soil. The number, quantity and activity of soil microorganisms increased with the increase of organic matter content, and had a significant positive correlation. The mineralization rate of soil organic matter is low, and it will not stimulate microorganisms such as fresh plant residues rapidly, but provide energy for microorganisms continuously and stably. Therefore, the soil rich in organic matter has stable and long-term fertility, which is not easy to cause excessive plant growth and fertilization.

6. Activate phosphorus, potassium and other nutrients

Generally speaking, phosphorus in soil pool does not exist in the state of rapid action, but in the state of slow action and slow action, so the availability of phosphorus in soil is low; soil organic matter has the characteristics of reaction with insoluble phosphorus, which can improve the solubility of phosphorus, improve the availability of phosphorus in soil and the utilization rate of phosphorus fertilizer.

Organic matter plays an important role in soil. Organic matter is processed into balls by organic fertilizer granulator, which is widely used in farmland to maintain soil fertility. There has been a great increase in crop yield.

Why so many people prefer to make granular fertilizer

Benefits of organic fertilizer equipment processing granular fertilizer
Organic fertilizer has the functions of water storage, water saving, water reducing, evaporation reducing and drought reducing. It can reduce the application of chemical fertilizer, reduce the damage of saline alkali, regulate the soil, activate the activity of soil microorganisms, overcome soil hardening, and improve soil permeability.

Organic fertilizer mainly comes from crop straw, chicken manure, cow manure, pig manure and garden pruning waste. These raw materials are rich in a large number of beneficial substances, processed by organic fertilizer production equipment, and converted into treasures. On the market, organic fertilizers are usually made into solid particles and then sold.

What are the advantages of using organic fertilizer equipment to process granular fertilizer?

Advantages of organic fertilizer equipment in processing granular fertilizer

1. It is more convenient to apply granular fertilizer. Some organic fertilizers are light in proportion and easy to be dispersed by the wind when applied in the field, and become particles for easy application.

2. In the process of organic fertilizer granulating, some inorganic components can be added into the fertilizer to improve the fertilizer efficiency. If inorganic components are added to powdered organic fertilizer, it is easy to absorb water and aggregate. Granular fertilizer avoids this trouble.

3. Raw materials must be low in water to get powdery fertilizer, and compost must be crushed. The main limiting factor in the production of organic fertilizer is that the water can not be removed and needs to be dried. The granulation process of fertilizer can produce high temperature without drying. It just needs cooling, which is very convenient.

Organic fertilizer granule

For a long time, the unreasonable soil structure has been caused by the unreasonable agricultural production. Organic fertilizer equipment alleviates various problems in soil. Organic fertilizer is rich in organic matter and various nutrient elements, with stable fertilization effect and long time.

However, if we do not carry out scientific treatment, there are still some disadvantages, such as inconvenient transportation, unsanitary, low utilization rate of chemical fertilizer. The granulator of organic fertilizer solves the problem of using agricultural waste and improves the efficiency of agricultural production.

With the development of economy, the suitable raw materials of organic fertilizer are gradually expanded, and the demand for granular organic fertilizer equipment is increasing. We provide organic fertilizer granulator, pan fertilizer granulator and flat model granulator to solve different fertilizer granulation problems.

Powdery Fertilizer Production Technology

Powdery organic fertilizer VS granular fertilizer

Powdery organic fertilizer is a kind of organic fertilizer without granulation and drying, which occupies the absolute main market share. Compared with granular bio organic fertilizer, powdery organic fertilizer has the advantages of less investment, lower production cost, less nutrient loss in the process of processing, lower price and less ecological pollution, which is generally accepted by the plantations and fruit and vegetable bases.

However, the powdered organic fertilizer has not been treated by disc granulator equipment, and its shape is not beautiful enough, so it is not suitable for machine seeding and application.

 Equipment for powder organic fertilizer production

The production of powdery organic fertilizer is relatively simple. The main production machine has the following five parts: organic fertilizer steering machine, forklift, distributor, pulverizer and screening machine (drum cutter or vibrating screen machine).

How to configure a powder fertilizer production line?

It is necessary to connect equipment and equipment with belt conveyor to form a complete organic fertilizer production line
1. The belt conveyor above the crusher is connected with the screened raw materials.
2. The belt conveyor above the screening machine is connected with fermentation raw materials.
3. The belt conveyor under the sieve machine connects and screens the finished products, and sends the finished products to the processing site for weighing and packaging.
4. The warehouse needs a conveyor for loading.

Fertilizer Application Basis

Organic fertilizer is rich in resources, including not only manure, straw, green manure, soil fertilizer, fertilizer, but also cake fertilizer, sea fertilizer and biogas. The results showed that the combined application of organic and inorganic fertilizers could promote the recycling of soil nutrients, increase crop yield, improve the quality of agricultural products, accelerate the harmless utilization of organic wastes and resource utilization, which is the fundamental guarantee of sustainable agricultural development. The industrial fertilizer production line also processes organic fertilizer and NPK fertilizer in proportion. So, how should organic fertilizer and inorganic fertilizer be used together?

Organic fertilizer / inorganic fertilizer

1. Fertilize less frequently. Nitrate nitrogen and ammonium nitrogen in the compound fertilizer will absorb part of the heat in the process of dissolving, which will affect the ground temperature and adversely affect the growth of crop roots. However, the normal growth of crops still needs adequate nutrient supply. Therefore, the compound fertilizer should be applied less in winter, and should be applied in the morning when the weather is good.

2. Inorganic fertilizer should be combined with pure biological fertilizer (no nitrogen, no phosphorus, no potassium). Long term use of chemical fertilizer will gradually consume the organic matter in the soil, resulting in the reduction of the number of beneficial microorganisms in the soil, the decrease of enzyme content, and the destruction of colloid, resulting in soil compaction, acidification and salinization. NPK fertilizer and organic biological fertilizer can improve soil, make sand reunite, loosen clay, inhibit pathogenic bacteria, restore soil micro ecological environment, improve soil permeability, improve water retention and fertilizer capacity. The pan granulator is used in chemical fertilizer plants to process organic and inorganic fertilizers to improve fertilizer efficiency.

3. Fertilizer should be suitable. For leafy vegetables and other vegetables, due to the fast growth, high nitrogen demand and low phosphorus demand, the compound fertilizer with high nitrogen content and low phosphorus content should be selected; for fruit melon, the potassium demand is more, the phosphorus demand is less, the compound fertilizer with high potassium and low phosphorus can be selected; For the next vegetable seedling, due to the large demand of phosphorus at seedling stage, the compound fertilizer with higher phosphorus content can be used as basic fertilizer, and the compound fertilizer with higher phosphorus content can be applied after planting slow seedlings.

The manufacturer of fertilizer granulation machine suggested that the fertilizer should be applied scientifically. According to the above principles, organic fertilizer and inorganic fertilizer should be used together to increase agricultural income.

How is fertilizer products produced?

Fertilizer machine knowledge, you should know how to produce fertilizer
Organic fertilizer and compound fertilizer are two common fertilizers in the market. Their processing technology is different, the fertilizer effect is also different. Organic fertilizer mainly uses artificial fermentation fertilizer as raw material, compound fertilizer is the granular fertilizer of NPK fertilizer.
