Technological process and equipment of NPK fertilizer production line
The process flow of NPK fertilizer production line can be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle grading, finished product coating and finished product packaging.
The NPK fertilizer production line process of rotary drum granulator includes raw material batching machine, fertilizer mixer machine, crusher, rotary drum granulator, particle dryer, particle cooler, coating machine for finished product, and quantitative packaging machine for finished product.
NPK production line has less investment and good economic benefits. The process layout of the complete set of equipment is compact, scientific and reasonable. Energy saving, no waste discharge, stable operation, reliable operation, convenient maintenance. Wide adaptability of raw materials, suitable for compound fertilizer, medicine, chemical industry, feed and other raw materials granulation, product granulation rate is high. It can produce various concentrations and types of compound fertilizer (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetized fertilizer, etc.). In particular, the granulation of rare earth and ammonium bicarbonate series compound fertilizer has filled the domestic blank.
