The npk production line is used to mix single N, P, K fertilizers to make granular fertilizers. Currently, in the NPK fertilizer industry, there are 2 processing methods for NPK fertilizers. The first is to turn the powdered fertilizer into NPK fertilizer granules. Another method is to mix the prepared single nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer granules.
•raw material. Crushing raw materials into fine powder is the first step in producing NPK fertilizers. If you buy the npk fertilizer production line with granulator, you can use cheaper powdered nitrogen fertilizer, phosphorus fertilizer and potash fertilizer. Here are 3 types of fertilizer shredders with different capacities, suitable for your compound fertilizer plant. They are new vertical crushers, chain crushers and cage crushers.
• Mixing powdered materials. After crushing, the raw materials can be stirred evenly with a fertilizer mixer. The prepared material can be sent to the granulation process. In addition, if you want to continuously produce NPK, you can use an automatic batching machine.
• Granulation process. Because the quality of the fertilizer granulator will affect the quality of nitrogen, phosphorus and potassium fertilizers. Therefore, you need to choose the right pelletizer for your plants. While this is an important step in the NPK fertilizer production line, it is not the last.
• Dry and cool. In order to reduce fertilizer moisture and increase the intensity of nitrogen, phosphorus and potassium fertilizers, it is necessary to use fertilizer dryers and coolers to process fertilizers.
•filter. When you have completed the above steps, there may be some particles that do not meet the packaging standards. Therefore, you should use a sieve to screen out undersized or oversized fertilizer particles.
•Package. This is the final step in the NPK fertilizer production process. After packaging, the commercial nitrogen, phosphorus and potassium fertilizers can be sold.
