NPK Fertilizer Production Line

NPK fertilizer is a kind of complex blending fertilizer which mainly contains any of elements of Nitrogen, Phosphorus or and Potassium. Those three elements are primary nutrients that the plants and crops need. For lack of the above nutrients, optimum environment for plant growth can not be reached. Under such circumstance, Tongda has npk fertilizer production line for sale to keep abreast of the customers’ requirements.

With the different techniques, there provides two npk fertilizer production systems for selection, one is the bulk blending fertilizer production line and the other is npk fertilizer granulating process. The former is to mix the N, NP or NPK fertilizer with other fertilizer like urea together by using batching machine, BB fertilizer mixer, coating machine and packer while the latter make fertilizer powder into pellets with a crucial process of granulation. Without doubts, we will provide those above with preferential price and high quality. And next, Tongda npk fertilizer production line is to be introduced.

Available process on how to make npk fertilizer by using Tongda npk fertilizer making machinery

There are two ways to make npk fertilizer production through our machines, one for npk fertilizer granulating line and the other for BB fertilizer production system.

NPK fertilizer granulating line goes on the following steps

  • Crushing process: For the sake of the occasion that the npk fertilizer begins at the powder or finished powdery fertilizer, there needs to processing the materials into powder. As a case in point, the material will be grinded into powder caused by high speed rotary and continuous impact of the material itself and of the internal surface of the machine. When the powder reaches your requirements, it will flow out from the discharge outlet. Thus, as for this step, cage crusher as well as chain crusher are suggestions for you.
  • Mixing process: If the material is powder in essence, you can use the double shafts horizontal mixer or single shaft mixer after batching. And the main purpose is to make all kinds of powder evenly so as to confirm nutrients in a regular ratio when granulating.
  • Pelletizing process: With the dry granulation process, double roller extrusion pellet machine demands the water content of the material within 5% to 10%. It is in this way that the process will discharge without three wastes (waste gas, waste water and waste residue) because of its no need in cooling and drying. If you worship perfection, you can put polishing machine which can make all the pellets same not only in size but also in shape. If the water content is beyond the scope, disc granulator is another recommendation.
  • Screening process: If there are unqualified pellets, the filter of our rotary screen machine will alter them out and make them go back to granulator to pellet again through conveyor. `
  • Coating process: There is rotary coating machine for you to avoid block prevention during storage and transportation in the process of npk fertilizer production.

NPK fertilizer blending line entails such steps as batching, mixing and coating, if you put BB fertilizer mixer into use.

How does Tongda fertilizer production systems balance different npk fertilizer components technically?

NPK fertilizer production is based on fertilizer which is mainly comprised of three elements– N, P and K and it has a special percentage of them. Then, how to balance them? Our automatic batching machine will help you solve the problem. The machine includes two parts: feeder and electric belt conveyor. If you want to produce npk fertilizer in a ratio of 19 – 19 -19, you can feed the material into the hopper and then set the value through automatic control box and finally, you can get materials with the required composition. In this way, you can achieve a simpler production process than manual weighing.

New and cheap methods of producing better npk fertilizer

We have cheap machines for npk fertilizer granulation and adopt wet and dry granulation methods in the process of npk fertilizer pelletization.

For one thing, when you produce bulk blending fertilizer, BB fertilizer mixer can help you save the area and simplify the fertilizer production process. Namely, what you need to do is just to batch the finished fertilizer into the BB fertilizer mixing machine and coat the qualified pellets. That is to say, you can save the area and cost for granulator and have a fast production for npk fertilizer with such a machine.

For another, from the view of granulation process, we adopt the dry granulation steps and wet granulation method. As mentioned above, our double roller extrusion granulator produce fertilizer through extruder technology and dry granulation steps (water content in about 10%). In this way, fertilizer manufacturers need not to be cautious of pollution and relevant adhesive. As for wet granulation steps, both rotary barrel and pan granulator can be applied. The material whose water content ranges from 25% to 30% is to be processed by these two units. With small investment but high efficiency and large production capacity, rotary drum granulating machine is a better choice. Furthermore, disc granulator specializes in powder management and it has the ability to change all kinds of the powder into pellets perfectly.

NPK calculation for fertilizer production

Fertilizer production requires seriously about the calculation about each kind of material and its moisture and so on.

At the beginning of fertiliser processing, producer batch your N,P,K fertilizer powders at proper ratio accurately. And here Tongda provides you fertilizer batching machine with high accuracy and working efficiency. It is suitable for you to batch your powdery materials with three or more hoppers.

Then, the most precise calculation about the granules can give for you by using our rotary screener. With slant angle and three different types of mesh size and three discharge holes, it can screen granules for three times, first for the smallest granular and powder, second for qualified and standard pellets and third for the biggest granules. Next, in case of meeting the fertilizer standards, we have rotary cooling and drying drum for you to remove the water of granules and reduce its high temperature.

At last, for large scale fertilizer production plant, there is ton packing machine for you. While for the small plant, single and/or double bucket packing scale are suitable for you.

What are the raw materials for production of npk fertilizer?

The raw materials for production of npk fertilizers involves two levels of fertilizers, the primary fertilizer and the secondary fertilizer. The first level is common seen fertilizers which are extracted from the N, P and K. Since different plants are scarce of different kinds of nutrients, the component of Nitrogen, Phosphorus and Potassium varies. The secondary level takes the nutrients of Ca and S as representations. Mixing them into nitrogen fertilizer, phosphorus fertilizer and/or potassium fertilizer when use the cage mixer, there will achieve a more fast-effective result.

Top 3 different types of npk fertilizers that most fertilizer plant manufacturers prefer to produce by using Tongda fertilizer production equipment
