In order to meet these requirements, extrusion granulation is now the method of choice for solid fertilizers by many foreign manufacturers. The extrusion granulation is to extrude the powdery or granular materials by a dry method to produce fertilizer granules meeting the requirements of users. The method comprises pressing solid material into block, crushing into granules (or extruding pasty material into short column with extruder), and granulating.

Present extrusion granulation forming device for fertilizer production has some shortcomings when using, at first, fertilizer need be dried after being extruded, but fertilizer granule only has one side directly to the heat source during the stoving, can make some fertilizer granules can't dry completely, thereby lead to the fertilizer granule of not drying to scatter again, and go out the hopper and collect the packing bag of fertilizer granule and fill the back, time space when changing the packing bag can lead to the fertilizer granule to drop and is polluted ground, in addition, because need inhale a large amount of air when the air heater is dried, can lead to dustproof filter layer need filter a large amount of dust debris, consequently, need often change, but dustproof filter screen changes comparatively trouble among the present extrusion granulation forming device for fertilizer production, waste time and energy, for this reason, we propose an extrusion granulation forming device for fertilizer production.
