The process flow of the powdery organic fertilizer production line
: When the powdery organic fertilizer is produced, it mainly absorbs the floating dust floating in the air. In the harmless treatment of livestock and poultry manure, aerobic strip fermentation is generally used, that is, the general stack fermentation. When fermentation, it is necessary to avoid wind and rain to reduce organic matter. Therefore, before fermentation, a rain-proof shed and a pile of fermentation tanks must be built. The powdery organic fertilizer production line cannot add compound fertilizer elements, nor can it be changed into a npk fertilizer production line
The following content is an introduction to the process flow
1. The ratio of raw materials per ton: 500kg of cow manure + 300kg of pig manure + 50g of bacterial residue (cow manure, pig manure can also be replaced by other livestock and poultry manure) Accessories: when the humidity of livestock manure is high, you can add appropriate straw, rice Shells, cakes and other materials with lower moisture content can reduce the moisture content of the fermented materials.
2. Strip pile: According to the above raw material ratio, carry out strip pile as needed. The length of the pile is not limited, with a width of 2 meters and a height of about 1 meter. When stacking, the materials need to be evenly stacked layer by layer. According to the size of the amount of manure processed each time, choose the appropriate width of the turning and throwing machine. The following is a trough turning and polishing machine with a lifting type, which can adjust the height of the turning pile and shorten the anti-return speed at the same time.
3. Add strains: expand the strains and residues in a ratio of 1:5 (the purpose of this is to dilute the strains and spread them evenly. For example, use 1kg strains with 5kg wheat bran or rice husk powder. Row). Generally, 1Kg strain can ferment 10-20 tons of manure and straw. In the case of a large amount of fermentation, it can be evenly mixed with a double-shaft horizontal mixer, and then sprinkled on the surface of the pile according to the number of piles.
4. Pile-turning and fermentation: Use a trough-type pile-turning machine to turn and throw the pile. When the temperature rises above 55 degrees, the pile is turned over every 1-2 days, and after 10-15 days of fermentation at 55 degrees, the pile can be put away.
5. Crushing: The fermented materials cannot be directly sold as commodities, because the long-term stacking will cause agglomeration and other phenomena. This is, the remaining large-speed materials need to be finely crushed by a high-humidity material crusher, and powdered organic fertilizer is obtained after crushing (pre-fermentation, in order to accelerate the fermentation process, auxiliary materials can be added to the crusher for crushing). If the powdery organic fertilizer production line wants to produce fertilizer granules, an organic fertilizer granulator must be added for fertilizer granulation after crushing. Generally, the Double Roller Granulator
is chosen because the Double Roller Granulator is cheap, but it has a long life and creates a lot of economy.
6. Screening: In order to improve the appearance, the powdered organic fertilizer is re-screened to obtain a uniform powdered material before packaging. After operating according to the above steps, it will become pure powdery organic fertilizer after being sieved by the drum sifter.
7. Packaging: The powdered organic fertilizer can be directly stored in the warehouse and sold after being packaged by an automatic packaging scale.
After these steps, powdery organic fertilizer can be produced. Of course, powdery organic fertilizer that meets the standard must be made. It is also necessary to determine the organic matter composition of fermented manure and straw fertilizer, add nitrogen, phosphorus and potassium content, and also need Adjust the proportion of auxiliary materials such as straw to determine the various content formulas of organic fertilizer.
