When making the urea-based compound fertilizer, you should mix urea with materials like TSP, MOP, DAP in a certain proportion. Then you apply the blending or the agglomeration and granulation method to produce the urea-based compound fertilizer pellets. Thus, you should set the granular production line of urea based compound fertilizer. The compound fertilizer equipment produced by SX can make the urea based compound fertilizer with the above two ways. What’s more, you can make 17-17-17, 24-10-6, 28-17-0 or other urea-based compound fertilizers through using SX fertilizer equipment. You can know the detailed information about urea based compound fertilizer production process and the machine selection from the following. We can also provide you with the case about designing the urea based compound fertilizer production line.

Why Do So Many People Set Up The Urea Based Compound Fertilizer Production Line?

The urea-based compound fertilizer produced with fertilizer has the advantages of high utilization rate and high economic benefit. It is precisely because of these two advantages that more and more fertilizer manufacturers have begun to produce urea-based compound fertilizers. You can learn more detailed information about the advantages from the followings.

In terms of the fertilizer utilization rate, when using the urea fertilizer alone, there will be some problems like like volatile and hydrolyze easily problems due to high solubility. These problem can reduce the urea utilization rate to 30%-40%. However, practical experiments have proved that when blending a variety of nutrients evenly in proportion by the fertilizer mixing machine, you will produce high-quality urea-based compound fertilizer. By being applied such compound fertilizer, the yield of crops is about 15% higher than that of using single nutrient fertilizer. Therefore, the urea based compound fertilizer has improved the fertilizer utilization rate.

In the fertilizer sales market all over the world, the urea fertilizer has a lower price. Therefore, when using the urea as the based fertilizer of the compound fertilizer, you will get 25% higher economic benefit than before.

From the mentioned above, you can make more benefits from producing the urea based compound fertilizer. while making the urea-based compound fertilizer. The followings will do a great help for you.

What Technology Can You Apply To While Setting Up The Urea Based Compound Fertilizer Production Line?

There are two methods you can apply to produce the urea-based compound fertilizer. One is the agglomerate granulation, and the other is blending method. The specific description are as follows.

Before granulation, you should crush the raw materials like urea, ammonium phosphate, potassium chloride and others by the crushing machine at first. Then, you can feed them into the granulation machine. With the help of steam or liquid, raw materials such as urea will gradually form granules under the mechanical action of the granulator. In order to ensure the strength of the fertilizer particles, you can add some granulation additives, such as formaldehyde, gypsum, etc. to improve the physical properties of the product. When there are magnesium elements in your urea based compound fertilizer formula, you should supplement magnesium hydroxide. You can also add the nitrification inhibitors, pesticides, and herbicides into the raw materials.

When you use the blending method to make urea-based compound fertilizer, you only need to evenly mix the basic fertilizer urea with other raw materials with similar particle size such as ammonium phosphate and potassium chloride. In this way, you can sell the compound fertilizer in bulk or in packaging.

Through comparing these two-production methods of the urea-based compound fertilizer, you can know that the blending method is simpler than the agglomeration and granulation. And when applying the blending method to make the urea based compound fertilizer, you can invest less than that of applying the agglomeration and granulation. However, the fertilizer particles produced by agglomeration and granulation will be not easy to stratified and more stable. Therefore, we recommend you choose the agglomeration method to make the urea based compound fertilizer. You can also provide us with your production yield and budget. We will recommend the suitable urea based compound fertilizer production line for you.

What Machines Will You Use Before Granulating The Urea Based Compound Fertilizer?

While applying the agglomeration granulation, there are four steps you should do at this stage. Moreover, you should buy the machines for steps of the crushing, screening,batching and mixing. The machine used in each step are as follows.

Vertical Type Crushing Machines from FPC Fertilizer Equipment Making Factory

Step1: Crushing Machine

While applying the agglomeration method, you should use the powder fertilizer as the raw materials. Therefore, you should use the fertilizer crushing machine to crush the urea, potassium chloride, ammonium phosphate and other materials to the powder with the diameter of less than 2.8mm. When you need to crush the raw materials, there are many types of the crushing machines in SX you can choose. We designed the urea crusher specially. While using the urea crushing machine, you can get the urea granules with the diameter of 0.3mm-0.5mm.

Step2: Screening Machine

After crushing, there must be some unqualified powders in the materials. You should use the screening machine to remove the substances. While screening, we recommend that you use the rotary screening machine produced by SX. You can sieve the 1-20 tons of the fertilizer per hour by using the SX rotary screening machine.

Step3: Automatic Batching System

When producing the high-nutrients urea-based compound fertilizer, you should accurately measure the amount of each raw material according to the production formula. In order to prorate the base fertilizer precisely, the automatic batching system is more suitable for you. There is the dynamic batching system in SX. By using the SX dynamic automatic batching system, you can batch the raw materials continuously. By this way, you can improve the urea based compound fertilizer production efficiency.

Step4: Mixing Machine

After the batching process, you should mix the raw materials completely to ensure the even distribution of nutrients. For the fertilizer mixing process, SX design many types of the mixer with the capacity of 1-20t/h. You can select the mixing machine based on your budget and urea based compound fertilizer production line yield.

The above four machines are that you need to use before granulation. There are different technical parameters of the production machines in SX. Once choosing SX, you will get multiple choice of the urea based compound fertilizer production equipment.

What Granulation Machine Can You Use For The Urea Based Compound Fertilizer Production Line?

While granulating the urea based compound fertilizer, we recommend you use the rotary drum granulation machine. For getting higher granulating efficiency, SX has improved the rotary drum granulating machine. You can know more about the technical parameters of SX rotary drum granulator from the following.

Rotary Drum Granulation Equipment Manufactured from FPC

In order to meet different needs of the customers, SX has designed the rotary drum granulation machines with different capacities. Generally speaking, you can get the rotary drum pellet making machine with the capacity of 1-30 t/h.

The rotary drum granulation machine made by SX is a kind of energy-efficiency production machine. For example, while using the SXZGZ-2080 rotary drum granulating machine with the capacity of 8-15 t/h, you will consume the energy of about 18 kw to produce the urea based compound fertilizer.

While designing the granulation machine, we consider the problem of land occupation area. Therefore, we try our best to reduce the land occupation area under the premise of ensuring high production. For example,there is a cylinder with the length of 8000mm and the diameter of 2000mm on the SXZGZ-2080 rotary drum granulating machine.

It is necessary to set the inclination angle when installing the rotary drum granulation machine. Such design can make the qualified granulated urea based compound fertilizer discharge from the granulator in time. In this way, the untreated powder fertilizer can be sent into the machine for granulation. The rotary drum pellet making machine produced by SX is inclined to the granule discharge port. The general tilt angle is 2-5°.

Because of the above advantages of SX rotary drum granulator, many fertilizer makes would like to deploy it. When granulating, the rotary drum fertilizer pellets making machine might be your best choice.

What Other Machines Do You Need After Granulation For Setting Up The Urea Based Compound Fertilizer Production Line?

To get the quality urea based compound fertilizer, you should still process the granulated fertilizer. There are still four processes you should know after granulation. You also need to deploy the machines for drying, coating, screening and packing. The detail descriptions are as follows.

  • After The Granulating, It Is The Drying Process.

After the granulating process, you will get the urea based compound fertilizer granules with the temperature of 60 ℃ and the moisture of 2.5%. In order to improve the strength of the fertilizer granules, you need to use the rotary drying machine to reduce the extra moisture.

Because the nitrogen element of compound fertilizer will start to hydrolyze at 60 degrees, and too high temperature will accelerate the formation of biuret which is harmful for the crops. The above two problems will lead to the destruction of nutrients in compound fertilizers. Therefore, you should control the drying temperature at the range of 60℃-70℃.

Because raw materials such as urea will undergo a hydrolysis reaction under conditions that contain a certain amount of moisture. And this reaction still occurs during storage. Such a reaction can cause the product to agglomerate. In order to avoid this situation, you need to reduce the moisture of the urea based compound fertilizer pellets to less than 2%.
