Why use NPK fertilizer press granulator compared to other granulation methods
Date:2020/11/02
Because the NPK fertilizer roller press granulator eliminates the drying process, and the returned material after granulation accounts for about 35% of the total feed, the proportion is low. Therefore, the fertilizer extrusion granulation process is simple and the investment is low.
According to IFDC (International Fertilizer Development Center) has carried out detailed research, it is proved that NPK fertilizer extrusion granulator is better than steam granulation, chemical granulation or slurry granulation for a new fertilizer equipment in developing countries. For a NPK fertilizer production equipment with an annual output of 120000 tons, the investment of steam granulation is 19.5% higher than that of extrusion granulation, while the investment of chemical granulation or slurry granulation is 88.8%. In terms of production cost (for 15-15-15) formula, steam granulation is 3% higher and chemical or slurry granulation is 12% higher.
