Formular for npk fertilizer production

From a technical point of view, the important factor in the formulation design of extrusion granulation products in NPK fertilizer production line is the characteristics of materials. Next, we discuss another aspect of the influencing factors, that is, the influence of the type of raw materials on the formula.

1. Material compatibility

Theoretically, any proportion of NP or K base fertilizer can be prepared, and trace elements and even pesticides should be added if necessary. However, materials must be limited by compatibility. The substances in the formula shall not have chemical reaction in the process of fertilizer manufacturing, and occasional reaction shall not be allowed.

2. Effect of urea on formula

The international fertilizer center has done a lot of experiments on the effect of urea on the performance of compound fertilizer, although the report does not mention the same example as the product formula we are studying, and most experiments do not carry out granulation on extrusion. Yes, but its conclusion is still useful to us.

Because urea absorbs moisture easily, the critical relative humidity of NPK compound fertilizer decreases significantly. At the same time, the international fertilizer center also found that this effect is more serious when potassium chloride is used as the potassium source of compound fertilizer.

Due to the low critical relative humidity, urea based compound fertilizer is easy to absorb water, which blocks the screen, pipeline, chute, etc.
When the temperature increases, the critical relative humidity of urea based compound decreases rapidly.

The production capacity of the dryer must be determined by many factors. Some urea based NPK fertilizers begin to soften at 70 ℃. If the outlet temperature of the dryer is higher than this temperature, the fertilizer particles will be too soft, the granulation process will be out of control (the particles are too large), and the internal scabs will form. Drying causes difficulties in screening and transportation.

In the same report, the international fertilizer center also tested other aspects of urea, such as water absorption, moisture permeability, water holding capacity, particle integrity, fluidity and agglomeration. The result is negative, which will have an adverse effect.

In short, the formula design test and production of extrusion granulation products in compound fertilizer production line show that the use of urea in compound fertilizer will encounter great trouble, not only because it affects the storage and transportation performance of products, but also because it also has a certain impact on the production process.

Granulation Equipment for Fertilizer Production Maintenance

Organic fertilizer is an indispensable raw material in today’s agricultural production. Organic fertilizer granulator converts materials into organic fertilizer and then processed into particles, which can help customers better package and use. Let’s talk about the steps and equipment needed in the production process of organic fertilizer.

Steps and equipment required for making organic fertilizer:

1. Ground strip stacker, crawler tipper, or material fermentation tank, trough thrower
2. Evenly sprinkle microbial agent, turn over the pile for fermentation, heat, smell, decompose and kill bacteria
3. Ferment for 15-20 days. According to different temperatures and times, use the dumper to improve the fermentation speed.

4. Complete fermentation, decomposition and out of the tank (ground type, direct stacking with forklift)
5. Coarse and fine screening with screening machine (the screened powdery fertilizer can be sold directly)
6. The screened large pieces are crushed by the crusher and returned to the screening machine.

7. Mix the required trace elements with a premixer,
8. Granulate with fertilizer granulator.
9. Enter the dryer and cooler for drying and cooling.

10. Automatic packaging machine for sale

Maintenance method of organic fertilizer granulator:

1. Start preheating and replace grease.
2. Replace the gear oil.
3. Reasonable maintenance, full and reasonable maintenance is very necessary.

4. Replacement of vulnerable parts. Vulnerable parts are the main working parts of the new organic fertilizer granulator.
5. Humanized production. The humanized culture and humanized operation of the equipment is a warm measure to ensure the normal operation of the machine.

Introduce the steps and equipment required for making organic fertilizer and the maintenance knowledge of the equipment. Hope to help you.

What is organic fertilizer and npk fertilizer?

Any material applied to the soil or sprayed on the ground of crops, which can directly or indirectly supply nutrients to crops, increase crop yield, improve product quality or soil properties, and make the soil fertile, is called fertilizer. Fertilizers that directly provide essential nutrients for crops are called direct fertilizers, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, trace element fertilizer and compound fertilizer.

Other fertilizers, mainly used to improve the physical, chemical and biological properties of the soil, so as to improve the growth conditions of crops, are called indirect fertilizers, such as lime, gypsum and bacterial fertilizers.

According to chemical composition, fertilizers can be divided into organic fertilizer and chemical fertilizer. Today I will introduce the basic information of organic fertilizer and chemical fertilizer.

Organic fertilizer is a kind of natural fertilizer which is used in rural areas, such as animal and plant residues or human and animal manure, and applied in situ or planted directly. It is also called farmyard manure.
What is chemical fertilizer? How to make chemical fertilizer by your own? Go to https://www.fertilizer-plants.com/compound-fertilizer-production-line/ for more.

In a narrow sense, chemical fertilizer refers to chemical fertilizer; In a broad sense, chemical fertilizer refers to all inorganic fertilizers and slow effect fertilizers produced in industry. Therefore, some people only call nitrogen fertilizer, but it is not comprehensive to call chemical fertilizer. Fertilizer is the general term of nitrogen, phosphorus, potassium and compound fertilizer.

In chemical fertilizer, the fertilizer containing two or more main nutrients such as nitrogen, phosphorus and potassium is called compound fertilizer. Therefore, NPK compound fertilizer is a kind of chemical fertilizer.
Our factory mainly produces organic fertilizer production and NPK fertilizer production equipment, such as dumper, mixer, crusher, granulator, etc.
