How to get NPK granules coated?

Processing sulfur coated urea in 15 t / h NPK fertilizer production line
Sulfur coated urea is a kind of coated slow release nitrogen fertilizer. In the process of NPK fertilizer production line, spherical urea is coated with a layer of molten sulfur to improve the physical properties of urea.

Sulfur coated urea is increasing in agricultural applications. With the increase of high concentration fertilizer application rate, the application amount of sulfur-containing super phosphate was relatively reduced, and the crop yield increased. The amount of desulfurization in soil increases, and the area of sulfur deficient land is expanding at home and abroad.

Therefore, the application of sulfur coated urea can not only improve the utilization rate of nitrogen, but also supplement the sulfur in soil.

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.

How to make fertilizer granules by extruding method?

Flat granulator is a kind of processing machinery in fertilizer plants. It is an extrusion fertilizer granulator, which is commonly used for fertilizer granulation.

The organic fertilizer production line of flat mold granulator has the characteristics of simple process, low equipment price and low power consumption, which is easy to use and maintain. The granulator can be used for granulation of organic fertilizer, compound fertilizer, feed and other materials. It has a wide range of material adaptability and many functions.

Application method of extruding fertilizer granulator flat die granulator

1. Before use, check whether the parts of the flat die granulator are tightened, whether the rotating parts are flexible, whether there is lubricant in the bearing, and whether the fertilizer granulator should be placed on a stable and stable ground. To check the power and voltage, the switch must be in the on position.

2. Check whether the clearance between the roller and the plate of the flat die granulator is kept at about 0.50 mm to prevent direct contact and abnormal wear. Select good mold aperture: select small mold when pressing small organic fertilizer; select large mold when pressing large organic fertilizer. During the operation of the organic fertilizer production line, attention should be paid to the site cleaning, and metal mixing into the powder and machine is strictly prohibited.

3. Start the flat mold granulator, check the granulation condition, check whether the surface of fertilizer particles is smooth and whether the temperature rise of particles is normal. By adjusting the bolts at both ends of the roller, the machine discharges normally.

3% of the material contained in the mold to prevent the mold from being corroded after the next time the mold is filled with oil.

Granular VS Powder Fertilizer

Fertilizer granulation is the key technology of organic fertilizer processing, and the quality of granulation directly affects the quality of final fertilizer. Organic fertilizer is suitable for green plants and animals, which is the key to carbon containing chemicals in the soil layer.

According to the processing route of organic fertilizer production line, organic fertilizer contains not only harmful substances, but also a lot of favorable substances.

Why granulation is needed in the production of organic fertilizer? Organic fertilizer equipment manufacturers analyzed the advantages of organic fertilizer and powder fertilizer.

1. It is very important to master the particle size distribution of fertilizer for the storage and transportation of chemical fertilizer. Granular fertilizer has good performance, and powder fertilizer is not easy to store. Fertilizer granules have good transport characteristics.

2. Low water soluble fertilizers are generally made into small particles to ensure that they melt reasonably and rapidly in the soil layer and are digested and absorbed by green plants.

3. Fertilizer granulation improves the production process of agriculture and animal husbandry. The fertilizer granule has the function of slow releasing fertilizer, which is convenient not to be blown away by the wind.
4. Some inorganic components can be added to the organic fertilizer production line and granulated by the fertilizer granulator according to the formula to improve the fertility of the organic fertilizer. However, powdered fertilizers and inorganic components can easily absorb water and form blocky materials.

How to make npk fertilizer granules?

With the continuous development of science and technology, the demand for agricultural fertilizer is higher and higher. For different crops, different regions and soils, the demand for fertilizer is different. In order to meet the actual needs of crop growth, in NPK fertilizer production line, fertilizer production enterprises should try to plant soil, apply fertilizer, prepare special fertilizer, adopt professional NPK fertilizer production process to produce compound fertilizer with multiple nutrients.

Roller granulator is widely used in NPK fertilizer production line. This kind of fertilizer granulator plays an important role in the production of compound fertilizer. The roller press granulator uses physical extrusion to produce elliptical particles. The roller granulator has greatly promoted the development of extrusion granulation of compound fertilizer and the extrusion granulation process of NPK fertilizer production line.

Production of compound fertilizer granules by rolling granulator
The characteristics of raw materials have an important influence on the granulation effect of roller granulator. The roller granulator can be used for granulation production of ammonium carbide, ammonium chloride, ammonium sulfate, vegetables, ammonium nitrate, magnesium sulfate, magnesium silicate, zinc sulfate, etc., as well as the granulation of NK compound fertilizers such as organic fertilizer and biological fertilizer.

On the other hand, the temperature of raw materials has a great influence on extrusion. In the extrusion process, the friction between the particles will generate heat and increase the material temperature. Generally speaking, the increase of temperature is conducive to the smooth completion of the extrusion process and the strength of the plate. However, too high temperature will also bring adverse effects, especially in the processing of urea based fertilizer materials, too high temperature will make the material adhere to the coil.

The roller granulator designed by Zhengzhou SX fertilizer equipment manufacturer adopts normal temperature extrusion granulation process, which can better maintain the characteristics of raw materials without affecting fertilizer efficiency. In order to avoid fertilizer bonding roller, the roll body of roller granulator was refined with a kind of anti-corrosion, wear-resistant, impact resistant and durable metal.
