NOVELTY - Producing special fertilizer, comprises mixing raw materials of the fertilizer in a mixer to obtain a mixture, adjusting the water content of the mixture to 60-65%, blending the mixture, stacking, fermenting, turning and throwing the fermented material, fermenting, stacking, post-composting, composting, transferring the composted material into a drying machine, drying, dedusting the air, pulverizing the dry mixture, sieving, pulverizing for a second time, adding the pulverized mixture into a second mixer, weighing materials in a specific ratio, mixing, packing the product and storing.    USE - The method is useful for producing special fertilizer.    ADVANTAGE - The method: utilizes special pulverizer to pulverize the fertilizer; enhances the production efficiency by 10 times; increases the pulverizing quality of the fertilizer; and controls the grain size of the pulverized fertilizer to less than or equal to 1mm.    DETAILED DESCRIPTION - Producing special fertilizer, comprises: (i) mixing the raw materials of the fertilizer in a specific ratio in a mixer to obtain a mixture, adjusting the water content of the mixture to 60-65%; (ii) adding into a blender and blending uniformly; (iii) stacking the mixture and fermenting; (iv) turning and throwing the fermented material by a turning machine, turning once in every 43-53 hours at 65-70 degrees C; (v) fermenting for 15-20 days for composting, post-composting after stacking for 15-20 days; (vi) transferring the composted material with a water content of 40-45% into a first drying machine, heating by a first hot air furnace at 60-70 degrees C to make the water content of the mixture to 30-35%, exhausting air of the first drying machine by a first draught fan and dedusting the air by a first deduster to make the exhausted air reach the emission standard; (vii) pulverizing the dry mixture by a primary pulverizer; (viii) sieving the primarily pulverized mixture by a first sieving machine, returning granules of larger size to the primary pulverizer to pulverize; (ix) secondarily pulverizing the smaller sized granules sieved by the secondary pulverizer for the granule size of the pulverized mixture to be less than 1 mm; and (x) adding the secondarily pulverized mixture into a second mixer, adding inorganic additives in a specific ratio, mounting an electronic scale on the second mixer, weighing materials in a specific ratio, mixing, packing the product and storing. An INDEPENDENT CLAIM is also included for a device for producing the special fertilizer, comprising a first mixer (1), the blender, the turning machine (4), a conveyor (6), the first drying machine (8), the primary pulverizer (13), the first sieving machine, the secondary pulverizer, an ingredient conveying system, a second mixer and a packing machine. The outlet of the first mixer is connected with the blender. The turning machine is arranged after the blender. The conveyor is arranged after the turning machine. The outlet of the conveyor is connected with the inlet of the first drying machine. The first drying machine is heated by a first hot air furnace whose upper part is connected with a first air suction pipe. The outlet of the first air suction pipe is connected with the first deduster. The first deduster is connected with the first draught fan. The first draught fan is connected with a smoke barrel. The outlet of the first drying machine is connected with the inlet of the primary pulverizer. The outlet of the primary pulverizer is connected with the inlet of the first sieving machine. The thick material outlet of the first sieving machine is connected with the inlet of the primary pulverizer. The thin material outlet of the first sieving machine is connected with the inlet of the secondary pulverizer. The outlet of the secondary pulverizer is connected with the inlet of the second blender. The inlet of the second blender is connected with the ingredient conveying system. The outlet of the second blender is connected with the packing machine. The second blender is provided with an electronic scale.
