How to dry wet compound fertilizer granules?

Particle drying is an essential step in the production line of nitrogen, phosphorus and potassium fertilizer. The state requires that the moisture content of compound fertilizer must be less than 30% to meet the national standard. Then in the process of compound fertilizer production, the water content of organic fertilizer after granulation reaches about 50%.

Sometimes even higher, the moisture content of dry particles has become an important link in fertilizer production.

In the drying process of fertilizer manufacturing process, it is very important to pay attention to the drying method. The fertilizer produced by the compound fertilizer equipment is full dry fertilizer. So how does compound fertilizer equipment produce dry fertilizer? What are the methods?

1. Mechanical dewatering method: mechanical dewatering method is to pressurize materials and then extrude some water. Common methods include pressing, sedimentation, filtration, centrifugation, etc. Mechanical dehydration is only used for the initial dehydration of raw materials. This method is not suitable for the production of particles.

Therefore, the moisture content of materials after mechanical dehydration is still high, generally 40-60%. However, mechanical dehydration is the most economical method, which is most suitable for the dehydration of poultry and animal feces.

2. Heating and drying method of compound fertilizer dryer: This is what we often call drum dryer drying method. It uses heat energy to enter the dryer barrel, and the temperature in the barrel reaches about 150 degrees. According to different materials, the temperature can be adjusted to evaporate the water in the materials.

A certain amount of heat energy is required to remove the water in the materials. This method usually uses air to dry the material. The air is preheated and sent to the dryer to transfer heat to the material, so that the water in the material evaporates to form water vapor, which is brought out of the dryer with the air.

The material can be heated and dried to remove the combined water in the material, so as to achieve the water content required by the product or raw material. This method can be applied to a variety of industries, and it is also one of the simplest methods to meet the requirements.

3. Chemical dehumidification method: this method uses hygroscopic agent to remove a small amount of moisture in gas, liquid and solid materials. Due to the limited dehumidification capacity of hygroscopic agent, it is now only used to remove trace moisture in materials. Therefore, this method is rarely used in production.

Innovational Technology for NPK Plant

1、 The granulation methods of domestic NPK fertilizer production line mainly include disc granulation, steam drum granulation, spray granulation, tower melting granulation, acid neutralization granulation and ammoniation drum granulation.

In addition to the disc granulator, the fertilizer granulator is mainly suitable for the production of large-scale compound fertilizer. The investment of relevant equipment is large, the construction time is long, the energy consumption is high, the production cost is high, and there are certain environmental pollution problems.

20t per hour drum granulation plant layout
20t per hour drum granulation plant layout

The extrusion granulation plant for producing multi-element potassium magnesium sulfate fertilizer has the advantages of small floor area, short process flow, convenient equipment operation, less construction investment and short construction period. Therefore, the compound fertilizer production line technology project is a short, flat and fast construction project, which has a certain popularization and application value in small compound fertilizer equipment production enterprises.

2. The traditional compound fertilizer production line adopts slurry method or humidified granulation method, which needs to introduce particles before granulation. In the process of fertilizer manufacturing, a large amount of energy is consumed in the drying of water, resulting in a large amount of waste gas and wastewater, Waste residue pollutes the environment.

Extrusion granulation of compound fertilizer production line is to extrude materials by external force. The granulation process does not need steam, which can save boiler construction investment and coal production cost. The compound fertilizer production line does not introduce water and has no drying process in the whole production process, which eliminates the large and expensive dryer in the traditional compound fertilizer production line equipment, and can be dried with fuel and drying equipment.

Therefore, the process of this compound fertilizer production line meets the needs of today’s energy-saving society.

3. In the traditional nitrogen, phosphorus and potassium fertilizer production line, hot blast stove and preheated air are used to dry the materials in the production process. Burning coal in hot blast stove will produce a certain amount of sulfur dioxide gas and pollute the atmosphere.

There is no need to burn fertilizer in the whole production process. Coal not only saves energy, but also does not produce sulfur dioxide gas. The traditional compound fertilizer production line will produce a large amount of dust and wastewater in the process of material crushing, mixing, drying, cooling and screening, which belongs to the process of cleaner production.

4. The fertilizer is less affected by the external environment (such as temperature and humidity) in the production process, with great operation flexibility and flexible process formula.

5. The compound fertilizer production line has high pelletizing rate, low moisture content, high particle strength, less system return and less caking in the production process, which has good economic benefits.

7 detailed process to make compound fertilizer

Process design description of NPK fertilizer production line:
1. Batch processing:
Electronic batching or disc batching.
2. Crushing process:
The mixed fertilizer proportioned according to the design requirements is sent to the raw material crusher for raw material crushing. The purpose is to crush various raw materials to a certain fineness. Basically, the particle size of raw materials is less than 1mm, which is conducive to the material in the granulator. Roll inside to meet the standard ball.

20t per hour drum granulation plant layout
20t per hour drum granulation plant layout

3. Granulation process:
The crushed mixture is conveyed to the fertilizer granulator through the conveyor. The liquid phase provided by the slurry or water in the extrusion granulator makes use of the centrifugal force brought by the rotation of the fertilizer granulator to turn the material into organic fertilizer. At present, it is better to use the disc granulator to produce organic fertilizer. The granulation rate of disc granulator can reach more than 90%, but the table output is low.
4. Drying process:
The granular materials are transported to the rotary three drum dryer through the conveyor. The hot blast stove is set at the inlet of the dryer to provide heat for the drying of materials in the dryer and evaporate the water in the formed materials into water. The steam is introduced into the dust collection chamber through the fan to remove dust. After the material enters the dryer, the liquid phase of the material is high and the ball strength is low. In order to ensure the sphericity of the material, we used it in the design of the dryer.
5. Cooling process:
The moisture content of materials after drying generally can not meet the water content requirements of organic fertilizer. Cooling in the cooler is very important for the NPK fertilizer manufacturing process.
6. Screening process:
The cooled organic fertilizer still has a certain temperature. After the organic fertilizer material enters the screening machine, the organic fertilizer material is roughly classified, and the screened fine powder is directly returned to the granulator for granulation. After screening, the screened coarse material is crushed by the return chain crusher, and then returned to the granulator for re granulation. The finished product is directly sent to the silo of the packaging scale. On the other hand, compound fertilizer materials are also used for screening projects. Cooling engineering plays a certain role in reducing temperature and preventing material caking.
7. Packaging process:
The coated finished organic fertilizer enters the silo of the packaging scale, automatically counts according to the set quantity, then puts it into the packaging bag, and then through the automatic sewing system, the sewn compound fertilizer can be stacked in the silo. Warehouse. In principle, the height of each stack shall not exceed 8 bags and the height shall not exceed 10 bags. The ground must be damp proof.

Nutrients in Organic Fertilizer Products

In the current process of agricultural production, we all advocate the application of organic fertilizer, but many farmers reflect that the nutrient loss of organic fertilizer is very serious, and they don’t know how to prevent and control it. Why? Organic fertilizer nutrients so powerful? Today, let’s look at the causes of nutrient loss.

How to make organic fertilizer with high qulaity? GO to https://organicfertilizerplants.com/organic-fertilizer-production-process/

1、 Prevent nutrient loss caused by gas volatilization

In the process of decomposition, nitrogen in organic fertilizer will be converted into ammonia, resulting in volatilization loss. Therefore, when it decomposes, it must be covered with plastic film without damage. It should not be piled up for too long and be used as soon as possible after maturity.

Bio Fertilizer Plant Design
Bio Fertilizer Plant Design

Therefore, we suggest that in the fermentation process, we can use the turnover machine to turn over, increase the ventilation and oxygen, promote the proliferation of microorganisms, so as to improve the fermentation speed. Our factory produces different types of composter for customers to choose.

2、 Prevent nutrient loss caused by chemical reaction

Human waste and ashes are an example. Many vegetable farmers still put some ash in human manure to prevent flies or odor. Plant ash is rich in potassium carbonate and alkaline in pH. Human excreta is acidic organic fertilizer, so the two meet, acid-base neutralization, nutrient loss. Therefore, human manure and ash should be separated from each other in composting and fertilization to avoid single, single and disposable use. Ash should not be poured into organic fertilizer to prevent ash from being drenched by rain. In addition to the examples of human manure and grass ash, we should also learn more about the chemical reactions between different materials to prevent nutrient loss.

3、 Prevent leakage and nutrient loss

For example, rice husk, duck dung, cow dung, and so on, ordinary people will water on the dunghill to make it easier to rot, but often nutrients will seep into the water because there is no anti leakage measures. Leakage and loss. Therefore, whether it is used in the pit or flat on the ground, it must be covered with plastic film to prevent nutrients from leaking with water. Therefore, water must be adequate. The water needed for organic fertilizer fermentation is generally 45% – 60% to avoid material inclusion. It is better to drop water loosely. How to turn these types of materials into organic fertilizer? Go to https://organicfertilizerplants.com/

In order to increase the nutrients of organic fertilizer and produce high-quality organic fertilizer, we must avoid these phenomena when we produce organic fertilizer.

Processing technology of sulfur coated urea in NPK fertilizer production line

Urea particles are heated by a heater and then coated with a sulfur-containing outer film. After urea coating, it is sent to powder machine by large angle belt conveyor. The powder machine sprays particles to seal the cracks of the coating and reduce the biodegradation of the sulfur coating. Two series of machines are used to ensure the quality of fertilizer. The coating of NPK fertilizer production line on the outer layer of urea ensures the slow release of fertilizer efficiency.

The outer envelope provides a physical barrier for urea, so that urea is slowly permeated by water and decomposed by microorganism. In the soil environment, urea gradually diffuses through the envelope, and releases nutrients slowly through the envelope cracks and the structure formed naturally on the envelope surface.

Fertilizer Coating Process

Coated fertilizer is a kind of NPK compound fertilizer widely used in agricultural production. It is popular with farmers for its low cost and high fertilizer efficiency. When NPK chemical fertilizer production line produces compound fertilizer, the treatment of coating machine is increased, which greatly improves the influence of fertilizer on crops.

The controlled release time of coating controlled release fertilizer is long, and the fertilization effect can be as long as 2 months to 1 year. NPK coated fertilizer can promote root growth, make crops mature early, solve the problem of crop fertilizer shortage caused by severe drought, and create favorable conditions for high yield of various crops.

NPK coated fertilizers can be used in the production of many crops. The output of rice, wheat, peanuts, corn, cotton, tobacco, vegetables, fruit trees, flowers, lawns and other crops increased significantly.

How to process NPK fertilizer production line

In the process of coating fertilizer, NPK fertilizer production line uses various nutrients, such as blood acid as coating layer, and the fertilizer is coated by coating machine. The coating can greatly reduce the loss of fertilizer and soil fixation, and greatly improve the utilization rate of fertilizer. The proportion of NPK and its trace elements in coated fertilizer processed by NPK fertilizer production line is determined according to crop demand and different soil conditions.

When we use NPK fertilizer production line to process coated fertilizer, we can produce special or general coated compound fertilizer for crops. This special NPK compound fertilizer has high fertilizer efficiency.

The application amount should be reduced according to the specific situation of crops and soil. The time interval of fertilization should be determined according to the length of controlled release cycle.

Therefore, when farmers use coated compound fertilizer, the production cost will be reduced.

How to make organic compost fertilizer at industrial scale?

Composting process is to reduce moisture and decomposition odor through decomposition and fermentation, so that manure can be used. Organic fertilizer equipment for composting livestock manure, not only can eliminate odor, but also can be used in agricultural production, provide nutrients for crops, and greatly improve crop income.

Compost fermentation, temperature rise, make it harmless. The feces of livestock and poultry contain pathogenic bacteria, parasite eggs and weed seeds. Compost is treated by organic fertilizer equipment system, and harmful substances are destroyed by the rise of fermentation temperature. During the composting process, the temperature of the fermentation product continuously rises to 70 ° C, which is enough to kill pathogens and parasites.

Compost fermentation requires oxygen for microbial activities. We can use composting turning machines with organic composting equipment to mix materials, increase material air and increase the gap between fermented materials.

Composting turning machine

Just by treating these composts, organic fertilizer equipment can be used in farmland. The composting process of organic fertilizer equipment is very simple, mainly screening and crushing process. The compost is sent to the hopper, and the screening material of drum screen is crushed by the chain crusher, which is the finished composting product.

Urea fertilizer coating

With the continuous improvement of agricultural science and technology, the promotion of high-yield varieties, the improvement of land re cultivation index, the vigorous development of economic crops, flowers and urban greening. The phenomenon of crop growth and soil nutrient ecological balance is becoming more and more serious, and the phenomenon of crop sulfur deficiency is becoming more and more serious.

Sulfur urea has become a popular fertilizer product in the market. It is coated with sulfur and other trace elements on the outside of urea by coater and pulverizer, so that the nutrients of fertilizer are released slowly. It is different from the technology of rotary drum granulator of compound fertilizer.

Why should sulfur coated urea fertilizer be used

1. sulfur coated urea can improve the utilization of fertilizer, similar to the granular fertilizer made by disc granulator, and can control the release rate of fertilizer nutrients. Especially, the utilization rate of nitrogen fertilizer can be greatly improved, the efficiency of fertilizer can be nearly doubled, and the agricultural investment can be greatly reduced and the environment can be protected.
2. increase crop yield greatly. The application of different soil and crop has a good effect on the yield.
3. the sulfur coated urea fertilizer can improve the quality of the crop products.
4. fertilizer can be used as soil conditioner, and the effect of the treatment of saline alkali land is good.
5. reduce labor input.

The application of sulfur coated urea fertilizer at one time can meet the needs of different growth stages of crops. With the high cost and shortage of modern agricultural labor cost, the application of sulfur coated urea in some crops also shows its characteristics.

For example, planting sugarcane, because the cane grows for months, it is not easy to mechanized fertilization after the crown is closed. In the early stage of self-growth, single fertilization can meet the needs of crops and is welcomed by sugarcane farmers. Strawberries grown in plastic mulch are also easy to apply nitrogen, so 70 percent of California’s strawberry growers use sulfur coated waste.

We provide a complete production line of sulfur coated urea, as well as the chemical fertilizer production equipment such as disc granulator, drum granulator, double roller granulator, coating machine, packaging machine and so on.

How to make granules fertilizer with pan granulation machine?

Organic-inorganic compound fertilizer is a compound fertilizer that integrates organic matter and inorganic fertilizer. Organic-inorganic compound fertilizer has various components, which can not only provide crop nutrients, but also improve soil biological activity and soil fertility, so it is widely used in cash crops.

Organic matter is an important component in organic-inorganic compound fertilizer, and its content directly determines the actual effect of bio-organic compound fertilizer. Therefore, the granulation process of organic-inorganic compound fertilizer production line is particularly important. The organic fertilizer disc granulation production line can realize the complete treatment of organic-inorganic compound fertilizer.

For the pan granulator, the addition of organic matter is also the key to granulation. Want to know how does the granulator make fertilizer granules by wet granulation method, welcome to https://www.fertilizermachinesale.com/pan-granulation-process/

Disc Pelletizer for Small Scale Cow Farm Manure Granualtion
According to the actual situation, several kinds of materials with abundant raw materials, low price and convenient processing can be selected as the raw materials of the pan granulator.

Organic fertilizer: chicken manure, pig manure, peat, plant ash, etc.
Inorganic fertilizers: urea, ammonium sulfate, superphosphate, calcium magnesium phosphate, potassium sulfate, potassium chloride, etc.

Organic compound fertilizer disc granulator

Organic fertilizer has strong water absorption and looseness, and its water content, fineness and other factors have a greater impact on granulation. Therefore, organic matter plays an important role in the production of disc granulators. On the premise of keeping the compound fertilizer and other inorganic nutrients unchanged, increasing the input of organic matter is an important way to improve the quality of biological compound fertilizer.

However, organic matter has strong dispersibility and has a greater impact on granulation. The organic content is too high, which is not conducive to the production of the pan granulator.

Experiments show that in the production line of organic fertilizer disc granulation, the amount of organic matter is about 25%-35%, and a better granulation effect can be obtained. The process of organic fertilizer disc granulation production line is suitable for the production of granular organic-inorganic compound fertilizer.

How to buy quality produced compound fertilizer products?

High quality compound fertilizer is produced by fertilizer granulator and other equipment. However, with the rise of social price, some bad businessmen use some inferior fertilizer as compound fertilizer to reduce the cost.

The formula is reasonable, targeted, rich in nutrition, sufficient in content and safe to use.
2. Reasonable selection of compound fertilizer according to local soil conditions
Fertilizer is divided into acid and alkali, soil is also divided into alkaline. For example, in saline alkali soil, we should choose nitrogen acid compound fertilizer (ammonium nitrate), which can not only supply the nutrients needed by crops, but also reduce the alkalinity of soil. At the same time, the adverse effects on crops are avoided.
3. The ratio of input and output must be calculated when selecting compound fertilizer
In order to select compound fertilizer, the ratio of input and output must be calculated and the compound fertilizer should be selected at a reasonable price. As the key problem of increasing agricultural production and income is to reduce agricultural costs, it is very important to choose fertilizers with good quality and reasonable price, otherwise there will be no return.
