The equipment used in the npk fertilizer production line is similar to that of the BB fertilizer production line. However, npk fertilizer’s technology in the production of granular fertilizers can be divided into wet granulation and dry granulation. At this time, the equipment used is different. If you want to know more, please continue to look down. The production of npk fertilizer requires high technical requirements. Our company strictly controls the ingredients in the early stage. And it has professional equipment to measure at all times to ensure quality and quantity.

Therefore, as a manufacturer with many years of experience in producing fertilizer equipment, we will provide you with expected pre-sales service and assured after-sales guarantee.

What proportion of npk fertilizer can our plant provide for you ?

Our company can produce npk fertilizers in various proportions, and can also customize according to the needs of customers. Let’s take a look at the following information for details.

Npk fertilizer process technology

Most npk fertilizers are granular, but the manufacturing process is indeed different. Divided into dry granulation and wet granulation.

There are not many equipment used in dry granulation. The first thing is to pretreat the raw materials. If the material is too large, you can buy a fertilizer crusher to crush it and then sieve it. Then you can mix according to customer needs. The double-roll extrusion granulator is suitable for dry granulation. Because it is dry granulation, you can directly package and put into the warehouse. The whole technological process is relatively simple and efficient.

The preliminary work of wet granulation is the same as that of dry granulation, which also requires raw material pretreatment and proportioning. The key is the step of granulation. Wet granulation is suitable for drum granulator and disc granulator. You can choose according to their needs. The moisture content of wet granulation is 45%-50%, but the moisture in bags is required to be below 25%, so a dryer is essential. A small amount of exhaust gas will be discharged during the drying process. In order to avoid pollution, you need to configure a dust collector purify the air. Once dried it is ready to cool and pack.

Cost of setting up a npk fertilizer plant

If it is to be made into powdered fertilizer, then the required equipment is on the powdered fertilizer production line. Such as fertilizer pulverizers, batching bins, manure mixers and packaging machines. It seems that the cost of powdered fertilizer is relatively low. If making it into granular fertilizer, it is related to the granulation production line equipment. The equipment in the early stage is also a manure crusher, a batching bin, and a fertilizer mixer, followed by a granulator, a dryer, a dust collector, and a cooler. In this way, it seems that the cost of producing granular npk fertilizer production line is a little higher. After comparing them, there will be advantages and disadvantages, but for fertilizer manufacturers, the benefits of granular fertilizers will be greater. Therefore, we recommend you to produce granular npk fertilizers, of course the most important thing is according to your needs.

Npk fertilizer production line layout

Customers generally have a lot of concerns about the choice of equipment. Our company will provide very reasonable pre-sales services to help customers plan and layout the fertilizer production site. So that the cost can be saved to the greatest extent.Our company will assign engineers to visit the site and give design drawings.

Plan the placement of equipment according to the size of your site, such as fertilizer crushers, granulators and packaging machines are small in size, so you can adjust the position at any time according to other equipment during planning. Larger equipment such as manure dryers and coolers should be placed after planning to avoid repeated movement.
