Advantages of sulphur-coated urea fertilizer

Sulfur coated urea, also known as sulfur coated urea, sulfur coated urea, controlled-release urea, is a new type of slow-release fertilizer. Similar to NPK granular fertilizer processed by rotary drum granulator, the product has the function of slow release and controlling fertilizer effect. According to different growth stages of crops, releasing nutrients according to nutrient requirements can reduce nutrient loss, improve fertilizer utilization, save resources and protect the environment. This product is not only an ecological and green agricultural product, but also a new type of product to replace common urea in the future.
1. The empty shell of sulfur fertilizer can store water. Through the soil, it can drive away the sterilization. Sulfur fertilizer and its compounds have been successfully applied to the improvement of saline alkali soil.
2. The product can not only supply sulfur to the soil, improve the yield of crops, but also improve the quality of crops to a certain extent.
3. Applying sulphur urea once can meet the needs of each growth stage of crops, which can greatly reduce the input of labor force.

A large number of studies show that most of the effective components of conventional chemical fertilizer are lost due to the volatilization and decomposition of drenching culture, resulting in less than 50% absorption by crops, that is, the utilization rate of conventional chemical fertilizer is less than 50%. Therefore, improving the utilization rate of fertilizer is the main content of fertilizer industry research. China’s research shows that more than 10 million tons of nitrogen are lost out of the world every year due to unreasonable fertilization, with a direct economic loss of over 10 billion yuan. The economic loss caused by the pollution caused by the loss of drainage to the people’s health and the quality of agricultural products is incalculable, with an upward trend in recent years.

Production process of sulfur-coated urea fertilizer

Different from organic fertilizer manufacturing process, sulfur-coated urea is coated with sulfur uniformly on the outside of ordinary urea, and then coated with a small amount of sealant and conditioner containing trace elements on the surface of sulfur. After this product is scattered in the farmland, urea nutrients are slowly released through the sulfur shell for crop absorption and utilization, which plays a role in prolonging fertilizer utilization. Chinese Tianci factory has specially designed a fertilizer production line with an output of 15t/h to process this fertilizer, so that urea can achieve the required fertilizer efficiency.

For general agricultural producers, in order to increase crop yields, the amount of fertilization must be increased accordingly, but when the fertilization reaches a high enough, and resources and the environment does not allow, it should seek to reduce the amount of fertilizer, through the use of new fertilizers. The new fertilizer formula can fully achieve the purpose of increasing production. The compound fertilizer granules and sulfur-coated urea fertilizer made by NPK fertilizer granulator are welcomed by the market.

Organic fertilizer made from waste vegetable leaves in vegetable greenhouses

fertilizer granulator Dec 2, 2020

Vegetable greenhouses will inevitably produce waste vegetable leaves. As the vegetable planting area continues to increase, a large number of stumps and leaves are produced. Every year melons, nightshade fruits, leafy vegetables and other vegetables produce nearly tens of thousands of dead branches and rotten leaves. For a long time, some farmers will randomly discard, let them rot or dry and burn the vegetables, which will cause the spread of pests and pathogens in the soil and air, and bring pollution to the environment. Organic fertilizer made from abandoned vegetable leaves in vegetable greenhouses has been vigorously promoted in the planting industry.

The processing technology of the organic fertilizer production line is to use a crusher to crush the collected vegetable leaves, add fermentation bacteria, stack the raw materials at high temperature, and then use a compost turning machine to turn the stack to make it fully rotted.

The crushed stem and leaves can be piled up and fermented at high temperature, and then they can be turned into organic fertilizer for reuse. Let the waste vegetable leaves turn into treasure, and solve a big problem of vegetable greenhouse planting in time. The fermented waste is made into organic fertilizer by the fertilizer granulator, and finally the vegetable leaf organic fertilizer is returned to the field. A large number of organic matter and nutrients promote the growth of vegetables better.

Relying on the technology of the organic fertilizer production line, the vegetable waste in the greenhouse has found a new way of recycling. The production and treatment technology of waste vegetable organic fertilizer has been put into use in many vegetable bases in China. And the use of processed organic fertilizer, vegetables look good, taste better. The implementation of organic fertilizer production line can reduce the environmental pollution and soil structure damage caused by discarded vegetable leaves, and help to enhance the safety of vegetables. Organic fertilizer equipment manufacturers hope that more vegetable bases will use this technology to realize the harmless use of vegetable leaves. We provide organic fertilizer machine, rotary drum granulator, disc granulator machine, organic fertilizer dryer, crusher and other fertilizer equipment.

Points for attention in roller extrusion granulation

fertilizer granulator Nov 20, 2020

Roller press granulator uses physical method to granulation. The whole process has no pollution and no waste. It is a very environment-friendly organic fertilizer machine. The following will lead you to understand the use of double roller extrusion granulator precautions.

Working principle of double roller press granulator

When the roller extrusion pelletizer is working, it is forced to roll the material into shape by two opposite moving roller skins of the granulation machine. Semi circular spherical cavities are regularly distributed on the two cylindrical roller skins. When the roller skin rotates against each other, the two semicircular cavities just form a complete spherical mold, and the materials inside are forced to be extruded into spherical particles. Due to the continuity of extrusion production, the particles and particles are connected together when they are just extruded, forming a cloth full of particles, which needs to be broken up by the crushing roller and divided into small round particles, and then screened from the screen to select the qualified particles.

The use of roller press granulator

When the double roller extrusion pelletizer is producing granular fertilizers, it should be noted that the ball sockets on the two roller skins should be properly positioned. If they are not adjusted in place, they will be misaligned during granulation and cannot produce qualified products. Granular fertilizer. In addition, after the particles are formed, they are released from the ball socket of the roller skin in time, so that uninterrupted production can be realized. If the formed particles are not released in time, complete particles will not be formed, which will affect the npk production line.

How to ferment sugar dregs quickly to make organic fertilizer

fertilizer granulator Sep 24, 2020

Filter mud, chicken manure, pig manure, furfural residue and sugar residue left from sugar processing in sugar factory can be used as raw materials for organic fertilizer production. They are fermented under suitable conditions to form organic matter, which is then processed by the organic fertilizer production equipment to provide nutrients for crops.

Method of fermenting organic fertilizer with sugar residue

1. Raw materials and requirements:

Main materials: animal manure, sugar dregs, Chinese medicine dregs, fruit dregs, mushroom dregs, distiller’s grains, furfural dregs and other bulk materials, biological bacterial fertilizer fermentation agent. The moisture content should be controlled at 50% – 65%. Due to the high acidity of fermentation material, quick lime should be used in advance to adjust the pH value to about 8.0.
Auxiliary materials: rice bran, sawdust, cake powder, straw powder, etc. the auxiliary materials are dried in powder form and rich in carbon.
Raw material ratio: main material: auxiliary material = 5:1-3:1

2. Operation method:

Mix all as required. Stack the material strips into piles, with a height of about 1.2m, unlimited length and ambient temperature. When the temperature of the pile rises to 45 ℃, the pile shall be turned over once every three days. If the temperature of the pile exceeds 65 ℃, it shall be turned over once every two days.
Signs of maturity: the temperature of the material is reduced, the material is loose, there is no original odor of the material, there is a slight smell of ammonia, and the pile is covered with white mycelium.
Compost stacking: it can be directly used after stacking and fermentation, or it can be used as the main material. Fertilizer granulator will process it into commercial organic fertilizer, bio organic fertilizer, organic-inorganic compound fertilizer, bio organic-inorganic compound fertilizer, etc.

Advantages of sugar residue organic fertilizer

High fertilizer efficiency and convenient application. Due to the fermentation period of only 7-15 days, the nutrients in the sugar residue are retained as much as possible; and due to the decomposition of microorganisms, some substances that are difficult to be absorbed and utilized by crops are rapidly transformed into effective nutrients. After fertilization, it can give full play to the fertilizer effect in a short time, quickly supplement the nutrients needed for crop growth, and maintain the fertilizer effect for a long time. The rotten filter mud is odorless, dry and loose, and easy to spread.

The organic fertilizer should not be mixed with strong acid, strong alkali, volatile chemicals and fungicides. Huaqiang factory provides a complete set of organic fertilizer equipment, and designs fertilizer production line for customers free of charge.

Technology of organic manure fermentation in hog farm

fertilizer granulator Sep 14, 2020

The biggest headache of hog farm is the problem of fecal treatment, because compost not only takes up space, but also easily causes odor. Under the pressure of environmental protection, pig manure treatment is a big problem. As long as the manure is properly disposed, it can not only solve the environmental problems of pig farms, but also bring extra income. The market price of organic fertilizer is high now. The raw materials are the excrement of livestock and crop wastes such as straw. Organic fertilizer machine manufacturers share the fermentation technology of hog manure, design organic fertilizer production line.

Technology of hog manure fermentation organic fertilizer

1. Add fermentation bacteria: 60% of livestock manure, 20% of food bacterial residue, 10% of straw and other materials with low water content (reduce the water content to 50%, which is the appropriate water content for fermentation), and 1% of bacteria fermentation agent. The purpose of adding fungicide is to improve the temperature rise speed, control the fermentation temperature at 65 ℃ ~ 70 ℃, eliminate the odor and sterilization in the fermentation process, accelerate the fermentation speed, and shorten the fermentation time to about 15 ~ 20 days.
Precautions for fermentation process: stir with compost turner machine every 2 days. In order to increase the oxygen content, the compost needs to be turned over continuously; at the same time, the fermentation strains need to be more evenly contacted with the materials, increase the maturity, and accelerate the process of fermentation maturity.

2. Smashing after fermentation and ripening: because some of the decomposed materials are too large for fertilizer application, it is necessary to smash these materials by semi wet material crusher to prepare for the next fertilizer granulator (the smaller the crushed particles, the easier to granulation). The crushed and stirred materials are powdery, which is not conducive to mechanical fertilization.

At present, many organic fertilizers on the market are fermented by animal manure, crop straw, pressed cake or beer dregs, monosodium glutamate dregs, etc. In the organic manure fermentation, chicken manure has the highest nutrient content, followed by pig manure, which is now fed with refined feed, so the nutrient content and organic matter content of pig manure are relatively high (the nutrient content of pig manure raised by farmers is relatively low), which is suitable for fermentation as organic manure. According to many experimental results, the effect of pig manure organic fertilizer is similar to that of chicken manure fermentation. Therefore, the market prospect of pig manure fermentation as organic fertilizer is very good. Tianci fertilizer machine manufacturer provide customers with organic fertilizer equipment, fertilizer production line, to help complete fertilizer manufacturing and processing.

What are the types of agricultural nitrogen fertilizer

fertilizer granulator Sep 12, 2020

It’s important to choose fertilizer for soil and crops

There are many types of nitrogen fertilizers, including compound fertilizers processed through the NPK fertilizer production line, so you may want to know which one to use. The key of agricultural fertilization is to choose suitable fertilizer for soil conditions and crops, and determine when to apply fertilizer. In order to avoid over fertilization and malnutrition, please pay attention to the application amount of fertilizer.
In agricultural production, soil condition is easily affected by climate and other factors, so it is not easy to carry out according to plan. However, it is important to understand and respond to daily situations.

1. Ammonium sulphate

Ammonium sulfate is a simple fertilizer containing only nitrogen. It is suitable for novices because it is relatively cheap and can maintain the effect for about a month after application. It is an easy-to-replenish fertilizer for nitrogen and protein synthesis because it is easily soluble in water, is familiar with soil, and has a high absorption rate in crops. However, due to these characteristics, the shelf life tends to shorten during high temperatures and rainy seasons. In addition, since the composition is a single fertilizer, it is necessary to use phosphate fertilizer and potassium fertilizer according to the purpose of the original fertilizer and the surface fertilizer. The factory can add phosphate fertilizer and potassium fertilizer when producing this fertilizer, and use a disc granulator machine to make granules.

2. Ammonium chloride

Ammonium chloride is a compound fertilizer containing 25% ammonia nitrogen. It is easy to dissolve and absorb in water, and a small amount of chlorine will remain after absorption, which is very important for the growth of fiber crops. Because it produces less hydrogen sulfide, it also has the function of preventing root rot, which can be expected to be effective for making delicious rice.

3. Ammonium nitrate

Ammonium nitrate contains the same amount of ammonia nitrogen and nitrate nitrogen. It is soluble in water and has an immediate effect, so it does not acidify the soil. However, due to its high moisture absorption, adhesion to wet leaves may have an adverse effect. In addition, due to its explosive nature, care must be taken when handling, e.g. do not mix it with oil.

4. Urea

Urea has a high nitrogen content, more than 40%, which is the same simple fertilizer as ammonium sulfate. Because it has an immediate effect, it’s useful to use it when you want it to take effect immediately. It can also be used as liquid fertilizer by dissolving it in water to make it suitable for foliar spraying. However, due to the high nitrogen content, you need to pay attention to over fertilization.

5. Lime nitrogen

Calcareous nitrogen containing calcium and nitrogen can be used as an effective pesticide to prevent pests and weeds at first. When pesticide components decompose in soil, they are mainly converted into ammonia nitrogen, which can be used as fertilizer effectively. Farmers have been using it for a long time, but due to the effects of inhalation and skin adhesion, they must be very careful when spraying, such as wearing protective masks or glasses.

There are several types of nitrogen fertilizers used in agricultural production. Since each nitrogen fertilizer has a certain effect, it is recommended to use them properly according to the cultivation environment. If organic matter is required, a decomposed organic fertilizer processed by compost turning machine can be used.
