How to deal with animal manure from large farms? One adult sheep can produce about 1.5kg of manure per day, 10,000 sheep can produce 15,000 tons of manure per day, and the annual output is 5,475 tons of sheep manure. This sheep manure can be sold as fertilizer.After 3 tons of sheep manure is dehydrated and fermented, it can be made into 2 tons of sheep manure as an auxiliary material for organic fertilizer. 5,475 tons of organic fertilizer can process about 2,488 tons of organic fertilizer, and can be equipped with a 5,000-ton organic fertilizer production line.
The 5,000-ton organic fertilizer production line can produce powder and granular fertilizers according to market demand. The machines included in the 5,000-ton organic fertilizer production line equipment include fermentation tumbling machine, semi-wet material crusher, mixer, disc granulator machine, screening machine, drum dryer, dryer, coating machine, etc. It can also be matched with a weighing packaging machine for automatic weighing and sealing packaging.

Among them, the fermentation process is very important. Only when the raw material is good, the organic fertilizer can pass the quality test. The following is a general fermentation process. Put pig manure, chicken manure, sheep manure and other agricultural manure into the fermentation tank for composting. In order to reduce the moisture content of the compost material, it is generally chosen to add a large amount of auxiliary materials with low moisture content, such as straw, hull and biogas residues. At this point, it is necessary to use a trench compost turner to mix these auxiliary materials with the manure compost. At the same time, as the decomposition continues, the temperature will continue to rise and the oxygen will continue to fall during the build-up. Therefore, it is necessary to promote oxygen, volatilize excess water, and take away excess heat. A pipe trench composting lathe can solve this problem very well.
After the fermentation is completed, the harmless treatment of manure is basically completed, but in order to improve the quality of crops as an organic fertilizer, crushing, mixing (adding nitrogen, phosphorus, potassium), organic fertilizer granulator machine, etc.
