L'engrais NPK est un engrais composé dont les principaux ingrédients comprennent l'azote, phosphore et potassium. Ces trois éléments sont des nutriments indispensables à la croissance des plantes. Ce type d'engrais composé est largement utilisé dans la production agricole car il contribue à améliorer le rendement et la qualité des cultures en fournissant une variété de nutriments importants nécessaires à la croissance des plantes.. Actuellement, il existe deux méthodes de traitement des engrais NPK dans l'industrie des engrais NPK. La première consiste à convertir les matières premières d’engrais en poudre en particules d’engrais NPK., et l'autre consiste à mélanger l'azote unique préparé, engrais phosphaté, et particules d'engrais potassiques. Concernant ces deux méthodes de production d’engrais NPK, Shunxin Machinery a conçu un équipement d'engrais NPK pour les fabricants d'engrais. Si vous souhaitez construire une ligne complète de production d'engrais NPK, alors Shunxin Machinery Company peut répondre à vos besoins. Ici vous pouvez trouver tout ce que vous voulez.

2 Types of NPK fertilizer production line

NPK Powder fertilizer production line

NPK powdered fertilizer production line mainly includes crushing equipment, mixing equipment, screening equipment, packaging equipment, etc..

The specific steps as follows:

First, it is advisable for you to prepare the raw NPK materials in advance, and then the raw materials are sent to the crushing equipment for thoroughly crushed into particles. After crushing, a screening machine is put to use to screen out large pieces of fertilizer. Subsequently, the powder fertilizer is then mixed evenly to achieve a balance of various elements. Enfin, the qualified particles will go through another screening process, and later they are ready for packaging. After packaging, you need to examine the quality of the finished NPK fertilizer powder, then the qualified NPK fertilizer can for sale.

NPK pellet fertilizer production line

NPK granular fertilizer production line includes more equipment and processes than powder production line, such as a feeder, granulation equipment, dryer, cooler, screening machine and packaging machine.

The specific steps as follows:

To begin with, the raw materials need to be mixed evenly to facilitate subsequent granulation. After preparing the raw materials, the crushing equipment can crush the NPK raw material into smaller particles. Then you will use a granulator to make the powdery raw materials into granules, and the mixed raw materials are granulated in the granulator. Afterwards, since the water content of the granulated pellets is too high, so there should have drying machine to dry out water moisture to improve the storage stability and ease of use of the fertilizer. The cooler is always an equipment that cooperate with the dryer, and is usually used to cool the fertilizer after drying. Enfin, you can package the granulated pellets for sale.

What is the key equipment in the NPK fertilizer production line?

NPK fertilizer granulation equipment is an important component in the NPK fertilizer production line. It is mainly used to convert NPK powder fertilizer into granules for easy use and transportation. Donc, if you have needs for NPK fertilizer granulation, then we have the following 2 types of Shunxin granulators for you to choose from:

Machine de granulation à tambour rotatif à vendre

Granulateur d'engrais à tambour rotatif est l'un des équipements clés dans la production d'engrais composés, which is suitable for larger scale NPK fertilizer plant and with an output of 1-30t/h . This is a commonly used and mature granulation equipment. It adds materials into a rotating cylinder and relies on the centrifugal force to form pellets. De plus, à travers une certaine quantité d'eau ou de vapeur pour ajuster l'humidité dans le cylindre, provoquant une réaction chimique suffisante des matières premières. Simultanément, à l'aide de la rotation du cylindre, making the material particles extruded and formed into balls. It has the advantages of high productivity and low energy consumption. En outre, it adopts the agglomeration wet granulation method, which makes the NPK pellets more uniform and round.

Disk granulating machine for sale

There is an inclined disc inside the granulateur à disque. The NPK fertilizer granules are made through the rotation of the disc and the humidity of the materials. The disk pelletizer is a common granulator, and it adopts wet granulation method. Through the rotating disk surface, the NPK material powder is pelletized under the action of centrifugal force, friction and gravity under certain humidity conditions. It not only has a simple structure and flexible operation, mais a également un taux de granulation élevé de plus de 93%. Pour cette raison, it is known as one of the first choices of many NPK compound fertilizer manufacturers because of its high efficiency.

What Are Suitable Raw materials for Manufacturing of NPK Fertilizer?

The raw materials of NPK fertilizers are mainly derived from natural resources and industrial by-products, including the following types:

Nitrogen fertilizer(N): urea, ammonium sulfate, ammonium nitrate, ammonium chloride, calcium nitrate, etc.. Among them, urea is the most commonly used nitrogen fertilizer raw material because of its high nitrogen content and good solubility.
Phosphorus fertilizer(P.): Mainly superphosphate, heavy superphosphate, calcium magnesium phosphate fertilizer, etc.. Another important phosphorus source is calcium dihydrogen sulfate, which can be directly used as a fertilizer raw material or can be converted into Phosphates are used
Potassium fertilizer(K): Potash minerals are the main source of potassium fertilizers, such as potassium chloride and potassium sulfate. En outre, there are some industrial by-products containing potassium that can also be used in fertilizer production, such as fireweed ash.

5 Advantages of NPK compound fertilizer granulation production line

【High efficiency】It meets the needs of large scale production, making the production efficiency much higher than traditional fertilizer production methods.
【Stable quality】Controlling and adjusting the production process can achieve stable product quality. Compared with manual or small-scale production, the compound fertilizer particles are uniform in size and the active ingredients are in a balanced manner.
【Réduire la pollution de l'environnement】Typiquement, during the production process, you can treat emissions with professional equipment to avoid direct emissions causing environmental pollution.
【Cost savings】Through automated control, the NPK compound fertilizer granulation production line can reduce labor costs and energy consumption, and reduce production costs.
【Easy to store and transport】The granulated compound fertilizer is plump and firm, easy to store and transport, and is conducive to market sales.
