Production device of organic fertilizer

The utility model relates to a production device of organic fertilizer, which is mainly used for producing organic granulated fertilizer and organic-inorganic mixed granulated fertilizer. The device comprises a first mixing machine (1), a stirring machine (2), a turning polishing machine (4), a conveying machine (6), a first drying machine (8), a coarse crushing machine (13), a first screening machine (14), a fine crushing machine (15), an ingredient conveying system (16), a second mixing machine (17), a first packaging machine (19), a granulating machine (21), a second drying machine (23), a cooling machine (28), a second screening machine (33), a second packaging machine (35), a third packaging machine (38) and a fourth packaging machine (41). The drying temperature during the whole production process is controlled at 60-70 DEG C, and the drying humidity is controlled at 30%-35%, thereby enabling the vast majority of microorganisms to survive and realizing obvious biological fertilizer effect. With the use of the special fine crushing machine, the crushing can be carried out under the water content of 30%-40% in the fertilizer, the production efficiency can be improved by 10 times, the crushing quality of the fertilizer can be greatly improved, and the particles of the crushed fertilizer can be controlled at 1mm and below.
