Working Principle of Shunxin Fertilizer Drying Equipment

Fertilizer dryer is a kind of equipment specially used to dry the moisture in fertilizer. Moreover, it is widely of use in the production process of organic fertilizer, compound fertilizer and mineral fertilizer. Furthermore, the fertilizer dryer uses hot air to evaporate and remove the moisture in the fertilizer, thereby reducing the moisture content of the fertilizer, improving the storage stability of the fertilizer, and making it easier to transport and use. Then, the following is the working principle of fertilizer dryer:

Design of Rotary Drum Dryer

Design of Rotary Drum Dryer

Fertilizer dryers often have a heating system, such as a combustion furnace, to generate hot air. And, heating systems can use a variety of fuels such as natural gas, coal, and biomass fuel to heat the air.

Wet fertilizer is sent into the dryer through a conveyor belt or other conveying equipment. At the same time, the heated hot air is sent into the inside of the dryer. In general, hot air is input from one end of the dryer and conducts heat exchange with the materials.

Typically, Fertilizer dryers usually take the form of a rotary drum. In the cylinder, the materials are thrown up and spread out. Thus, it increases the contact area with hot air and promotes the heat exchange process. The cylinder is usually placed slightly tilted, and the material moves from the high end to the low end of the cylinder under the action of gravity. During the process, the material fully exchanges heat with the hot air and the moisture is evaporated.

The hot air that takes away the moisture from the dryer, and the dust and fine particles are of reduction through the dust removal system to ensure that the emissions meet the standards. Then, the dried fertilizer is discharged from the outlet of the dryer and sent to the next process or storage area through conveying equipment.

Through the above process, the fertilizer dryer can effectively reduce the moisture content in the fertilizer, improve its quality and facilitate storage and transportation. Besides, the design and operating parameters of the fertilizer dryer (such as drying temperature, cylinder speed, hot air flow, etc.) need to be adjusted according to the specific fertilizer type and required drying degree to achieve the best drying effect.

What are the necessary supporting equipment for a drying machine?

The efficiency and performance of a dryer depend largely on its necessary supporting equipment, especially the heating source. When using a dryer to process materials, natural gas combustion furnaces and hot air furnaces are two common heating devices that provide the necessary heat energy for the drying process.

  • 【Natural Gas Burner】 The natural gas burner is a heating device that uses natural gas as fuel. Moreover, it is mainly of use for fertilizer drying in the fertilizer production process, and can also be as a heat source for drying other raw materials. Then, natural gas burners widely occur in fertilizer production due to their high efficiency, clean combustion and easy operation.

    • Working principle: It generate heat by burning natural gas. And, the combustion chamber mixes natural gas with air and ignites it, producing a large amount of heat energy. Also, the heat exchange device transfers this heat energy to the flowing air or other media, and the hot air generated subsequently dries the materials in the dryer.

  • 【Hot Blast Furnace】Hot blast furnaces are widely of use in the production of fertilizers. Moreover, they can use natural gas, coal, biomass, electricity and other energy sources as fuel. Yushunxin hot blast furnace is lined with manganese steel plates on the outside and refractory bricks on the inside, making it easy for users to hoist, install and use at any time. What’s more, we can customize different models according to customer requirements.

    • Working principle: A hot blast stove heats air or other gases by burning fuel (such as coal, oil, natural gas, etc.) to generate hot blast. Also, hot air stove contains a combustion chamber where it burns fuel to generate heat. Then, it transfers this heat to the air through a heat exchanger. And finally, it delivers the heated air to the dryer to dry the material.

How to improve fertilizer quality in the subsequent process after drying?

The efficiency and performance of a dryer depend largely on its necessary supporting equipment, especially the heating source. When using a dryer to process materials, natural gas combustion furnaces and hot air furnaces are two common heating devices that provide the necessary heat energy for the drying process.

Other Auxiliary Equipment

Since the temperature of the dried fertilizer is high, it needs to be of cooling down by a cooler to prevent the fertilizer from getting wet and clumping. In addition, cooling also helps improve fertilizer storage stability. Coolers usually use a rotary structure and work similarly to dryers, but cold air is blown in here.

The drying and cooling fertilizer may have particles of different sizes, and screening can be of use to separate the fertilizer into different grades and remove particles that are too small and too large. For this step, you can use screening equipment such as vibrating screens or trommel screens.

For certain types of fertilizers (such as controlled-release fertilizers), a coating machine can be of use to add a shell to the fertilizer granules after cooling and screening. This shell can improve the nutrient release efficiency of fertilizers, reduce nutrient loss, improve fertilizer efficiency. And, it improves the physical properties of fertilizer particles, such as moisture resistance and pressure resistance.

According to market demand, fertilizers are of package into bags or bags of different specifications. High-quality packaging can not only better protect fertilizers and prevent moisture, agglomeration and other problems, but also help improve the market competitiveness of products. Thus, an automatic packaging machine can effectively improve packaging efficiency and accuracy.

Lastly, the separated gas will enter the dust collector through the pipeline for purification treatment. Then, the purified gas will be discharged into the atmosphere to meet environmental protection requirements.

Fertilizer dryers play an indispensable role in mineral fertilizer production. During the production process of mineral fertilizers (such as nitrogen fertilizers, phosphate fertilizers, potassium fertilizers, etc.), the water content is often too high, which not only affects the storage and transportation of fertilizers, but may also affect its application effect. Therefore, proper drying is an important step to ensure fertilizer quality and efficiency.
