In September 2024, a Nigerian customer asked through the website: How much does the 300tons/day bio NPK fertilizer production cost on sale at YUSHUNXIN? At the same time, what are the processes for producing bio NPK fertilizer granules? What equipment and related services does YUSHUNXIN configure for this production line? In the end, the transaction price of the 300tons/day bio NPK fertilizer production line was about $450,000. The following are the details of our communication.

The Algerian customer’s bio NPK fertilizer factory works 10 hours a day. Therefore, we planned a 15 ton/hour NPK biofertilizer production line for them. In the end, the Nigerian customer purchased the production line for about $450,000. The NPK bio fertilizer production cost is generally related to the output and the form of the bio NPK fertilizer. Of course, you can purchase it according to your actual conditions. YUSHUNXIN is the source factory and can formulate a bifertilizer manufacturing plan for you at the most favorable price.

At the same time, the customer asked how to quickly make bio NPK fertilizer granules. Generally speaking, there are two processes for granulating bio NPK fertilizer: dry granulation and wet granulation. Dry granulation technology uses a roller compactor granulator. It is granulated by double roller extrusion. Although this can save costs such as drying and cooling, the production capacity is limited and cannot meet the customer’s production of 300 tons per day. Therefore, we recommended wet granulation technology to the customer – using liquids such as water or steam to agglomerate powdered NPK fertilizer raw materials into balls. NPK drum granulator is a good choice.

First, use a dynamic batching machine to proportion the N, P, K and organic waste in a suitable proportion. Then use a double-shaft horizontal mixer to mix them evenly. Since the customer chose wet granulation of bio NPK fertilizer and the capacity is 300 tons per day, we advise a rotary drum pelletizer. It can achieve continuous production and the granulation rate can reach more than 90%. At the same time, in order to maintain the stability of the bio NPK fertilizer granules, you also need drum dryer and cooling equipment. Next, use a packaging machine to complete the final process for sale. The double-bucket automatic packaging machine is suitable for 300 tons of bio NPK fertilizer production per day.
