Organic fertilizer refers to a type of fertilizer made from animal and plant residues or feces as the main raw material, through fermentation, maturation, granulation and other processes. It has the advantages of improving soil, increasing soil fertility, improving crop yield and quality, and reducing fertilizer pollution. With the demand for green development in agriculture, the market demand for organic fertilizers is increasing day by day, but at the same time, it also faces problems such as insufficient raw material supply, high costs, and uneven quality. In order to solve these problems, some enterprises and institutions have invested in the construction of organic fertilizer production lines, adopting advanced technology and equipment to achieve large-scale, standardized, and automated production of organic fertilizers.

     The organic fertilizer production line mainly includes fermentation turntables, high humidity material crushers, drum screening machines, flat mold granulators, cooling dryers, finished product coating machines, automatic packaging machines, etc. Among them, the fermentation turning machine is a key equipment for harmless treatment and decomposition transformation of raw materials, which can effectively kill bacteria and insect eggs, increase organic matter content and activity; Flat mold granulator is an important equipment for turning decomposed raw materials into granules, which can improve the yield and density of finished products, facilitate transportation and application; The drum screening machine and high humidity material crusher are necessary equipment for screening and crushing particles, which can ensure the uniformity and stability of the product.
