Special fertilizer production equipment
2010
The utility model relates to special fertilizer production equipment which is mainly used for the production of organic granulated fertilizer and organic-inorganic mixed granulated fertilizer, and comprises a first mixer (1), a stirrer (2), a stack-turning machine (4), a conveyor (6), a first dryer (8), a coarse pulverizer (13), a first screening machine (14), a fine pulverizer (15), an ingredient conveying system (16), a second mixer (17) and a packer (19). During the entire production process, the drying temperature and the drying humidity are controlled between 60 and 70 degrees and between 30% and 35% respectively to ensure the survival of most microbes, thereby guaranteeing the effectiveness of bio-fertilizer. The special fine pulverizer can carry out pulverization when the water content of fertilizer is between 30% and 40%, thereby increasing the production efficiency tenfolds and greatly improving the effectiveness of fertilizer pulverization. Pulverized fertilizer granules are no larger than 1mm in size.
