With the rapid development of pollution-free food, green food and organic food, the production of refined commercial organic fertilizer and organic-inorganic compound fertilizer from agricultural wastes such as livestock and poultry manure has become the development direction of organic fertilizer. Livestock and poultry manure as fertilizer can not only solve the problem of waste disposal, but also improve and fertilize the soil. Taking the fertilizer granulation production line with an annual output of 10,000 tons as an example, which raw materials and production equipment are needed for the production of organic fertilizer and special fertilizer.
Raw material processed in organic fertilizer production line
Compost raw materials: livestock manure: calculated by 2000 adult pigs, the daily output of pig manure is about 16 tons, with an annual output of about 5760 tons.
Supplementary materials: straw, mushroom residue, sawdust, forest humus, peat, weathered coal, etc. 4000 tons per year.
Addible inorganic fertilizers: nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer.
Fertilizer plants first need fermentation sites, storage plants, production and processing workshops and other production sites.
Basic equipment: crusher, mixer, compost turning machine, drum screener, fertilizer granulator (disc granulator, drum granulator, new type organic fertilizer granulator, flat die granulator, etc.), automatic packaging machine, loader feeding hopper. The specific fertilizer equipment needs to be determined according to the fertilizer field and production process.
