At present, local fertilizer producing ways are: Extruding, Grain Cluster, Slurry. Extruding Ways due to the limits on appearance quality, grade and machine sowing fertilizer has been out of fashion. Slurry way because of complicated processing and too much investment only is used by few large enterprises, meanwhile Grain Cluster way due to simple processing, less investment is widely used whose main defects is that experience factor is very important during the production. Others, kind of raw material and ingredient has great effort on processing. Especially for high nitrogen urea-based rehabilitation (co-) mixed fertilizer, N/K type and some special ingredient fertilizer, production is too hard, and sometimes even could not be produced. Spraying granulation equipment made by Pengfei group has solved this problem, largely increased the granulating efficiency, enlarged the flexibility of operation, improved the appearance quality, increased the output, decreased power consumption and strengthened the products? Competition in the market.
