Potassium sulfate is suitable for chlorine-free crops and can improve crop yield and quality. Potassium nitrate not only provides potassium for crops, but also provides nitrogen. It is an important raw material for the production of compound fertilizer. It is a physiological neutral fertilizer.

Npk fertilizer production process mainly includes feeder, disc mixer, chain crusher, double roller press granulator, drum dryer, drum cooler, drum screen machine, finished product warehouse, automatic packaging machine, belt conveyor, dust settling chamber, heat exchanger.

The use of npk production line granulation, extrusion granulation is the world's most feasible granulated potash fertilizer manufacturing method. At present, the world's most advanced extrusion granulation technology is roll extrusion granulation, which has the characteristics of low energy consumption, low investment and no need to add adhesives, large size range of applicable raw materials, wide range of capacity, and good economic benefits.

Granular potash fertilizer has great market demand and broad development and utilization prospects. Granular potash fertilizer has good physical properties, no dust during loading and unloading, long-term storage without clumping, easy to spread when fertilizing, but also can play a grade release effect, improve the utilization rate of fertilizer, its production to meet the needs of the market.
